Breast Cancer – Treatment Options

In cancer care, doctors specializing in different areas of cancer treatment—such as surgery, radiation oncology, and medical oncology—work together to create a patient’s overall treatment plan that combines different types of treatments. This is called a multidisciplinary team. Cancer care teams include a variety of other health care professionals, such as physician assistants, oncology nurses, social workers, pharmacists, counselors, nutritionists, and others. For people older than 65, a geriatric oncologist or geriatrician may also be involved in care. Ask the doctor in charge of your treatment which health care professionals will be part of your treatment team and what they do. This can change over time as your health care needs change.

A treatment plan is a summary of your cancer and the planned cancer treatment. It is meant to give basic information about your medical history to any doctors who will care for you during your lifetime. Before treatment begins, ask your doctor for a copy of your treatment plan. 

The biology and behavior of breast cancer affects the treatment plan. Some tumors are smaller but grow quickly, while others are larger and grow slowly. Treatment options and recommendations are very personalized and depend on several factors, including:

Even though the breast cancer care team will specifically tailor the treatment for each patient and the breast cancer, there are some general steps for treating early-stage and locally advanced breast cancer.

For both DCIS and early-stage invasive breast cancer, doctors generally recommend surgery to remove the tumor. To make sure that the entire tumor is removed, the surgeon will also remove a small area of healthy tissue around the tumor, called a margin. Although the goal of surgery is to remove all of the visible cancer, microscopic cells can be left behind, either in the breast or elsewhere. In some situations, this means that another surgery could be needed to remove remaining cancer cells.

For larger cancers, or those that are growing more quickly, doctors may recommend systemic treatment with chemotherapy or hormonal therapy before surgery, called neoadjuvant therapy. There may be several benefits to having other treatments before surgery:

After surgery, the next step in managing early-stage breast cancer is to lower the risk of recurrence and to get rid of any remaining cancer cells. These cancer cells are undetectable but are believed to be responsible for a cancer recurrence as they can grow over time. Treatment given after surgery is called adjuvant therapy. Adjuvant therapies may include radiation therapy, chemotherapy, targeted therapy, and/or hormonal therapy (see below for more information on each of these treatments).

Whether adjuvant therapy is needed depends on the chance that any cancer cells remain in the breast or the body and the chance that a specific treatment will work to treat the cancer. Although adjuvant therapy lowers the risk of recurrence, it does not completely get rid of the risk.

Along with staging, other tools can help estimate prognosis and help you and your doctor make decisions about adjuvant therapy. This includes tests that can predict the risk of recurrence by testing your tumor tissue (such as Oncotype Dx™ or MammaPrint™). Such tests may also help your doctor better understand the risks from the cancer and whether chemotherapy will help reduce those risks.

When surgery to remove the cancer is not possible, it is called inoperable. The doctor will then recommend treating the cancer in other ways. Chemotherapy, targeted therapy, radiation therapy, and/or hormonal therapy may be given to shrink the cancer.

For recurrent cancer, treatment options depend on how the cancer was first treated and the characteristics of the cancer mentioned above, such as ER, PR, and HER2.

Descriptions of the common types of treatments used for early-stage and locally advanced breast cancer are listed below. Your care plan also includes treatment for symptoms and side effects, an important part of cancer care. Take time to learn about all of your treatment options and be sure to ask questions about things that are unclear. Talk with your doctor about the goals of each treatment and what you can expect while receiving the treatment. These types of talks are called “shared decision making.” Shared decision making is when you and your doctors work together to choose treatments that fit the goals of your care. Shared decision making is particularly important for breast cancer because there are different treatment options. It is also important to check with your health insurance company before any treatment begins to make sure it is covered.

People older than 65 may benefit from having a geriatric assessment before planning treatment. 


Surgery is the removal of the tumor and some surrounding healthy tissue during an operation. Surgery is also used to examine the nearby axillary lymph nodes, which are under the arm. A surgical oncologist is a doctor who specializes in treating cancer with surgery. 

Generally, the smaller the tumor, the more surgical options a patient has. The types of surgery include the following:

Lymph node removal and analysis

Cancer cells can be found in the axillary lymph nodes in some cancers. It is important to find out whether any of the lymph nodes near the breast contain cancer. This information is used to determine treatment and prognosis.

Sentinel lymph node biopsy. In a sentinel lymph node biopsy, the surgeon finds and removes a small number of lymph nodes from under the arm that receive lymph drainage from the breast. This procedure helps avoid removing multiple lymph nodes with an axillary lymph node dissection (see below) for patients whose sentinel lymph nodes are mostly free of cancer. The smaller lymph node procedure helps lower the risk of several possible side effects. Those side effects include swelling of the arm called lymphedema, the risk of numbness, as well as arm movement and range-of-motion problems with the shoulder, which are long-lasting issues that can severely affect a person’s quality of life.

The pathologist then examines these lymph nodes for cancer cells. To find the sentinel lymph node, the surgeon usually injects a dye and/or a radioactive tracer behind or around the nipple. The injection, which can cause some discomfort, lasts about 15 seconds. The dye or tracer travels to the lymph nodes, arriving at the sentinel node first. If dye is used, the surgeon can find the lymph node when it turns color. If a radioactive tracer is used, it will give off radiation which helps the surgeon find the lymph node.

If the sentinel lymph node is cancer-free, research has shown that it is likely that the remaining lymph nodes will also be free of cancer. This means that no more lymph nodes need to be removed. If only 1 or 2 sentinel lymph nodes have cancer and you plan to have a lumpectomy and radiation therapy to the entire breast, an axillary lymph node dissection may not be needed. 

Axillary lymph node dissection. In an axillary lymph node dissection, the surgeon removes many lymph nodes from under the arm. These are then examined for cancer cells by a pathologist. The actual number of lymph nodes removed varies from person to person. An axillary lymph node dissection may not be needed for all women with early-stage breast cancer with small amounts of cancer in the sentinel lymph nodes. Women having a lumpectomy and radiation therapy who have a smaller tumor and no more than 2 sentinel lymph nodes with cancer may avoid a full axillary lymph node dissection. This helps reduce the risk of side effects and does not decrease survival. If cancer is found in the sentinel lymph node, whether more surgery is needed to remove more lymph nodes depends on the specific situation.

Most people with invasive breast cancer will have either a sentinel lymph node biopsy or an axillary lymph node dissection. However, these procedures may be optional for some patients older than 65. This depends on how large the lymph nodes are, the tumor’s stage, and the person’s overall health.

A sentinel lymph node biopsy alone may not be done if there is obvious evidence of cancer in the lymph nodes before any surgery. In this situation, a full axillary lymph node dissection is preferred. Normally, the lymph nodes are not evaluated for patients with DCIS and no invasive cancer, since the risk of spread is very low. However, the surgeon may consider a sentinel lymph node biopsy for patients diagnosed with DCIS who choose to have or need a mastectomy. If some invasive cancer is found with DCIS during the mastectomy, which happens occasionally, the lymph nodes will then need to be evaluated. Once the breast tissue has been removed with a mastectomy, it is more difficult to find the sentinel lymph nodes since it is not as obvious where to inject the dye.

Reconstructive (plastic) surgery

Women who have a mastectomy may want to consider breast reconstruction. This is surgery to re-create a breast using either tissue taken from another part of the body or synthetic implants. Reconstruction is usually performed by a plastic surgeon. A woman may be able to have reconstruction at the same time as the mastectomy, called immediate reconstruction. She may also have it at some point in the future, called delayed reconstruction.

For patients having a lumpectomy, reconstruction may be done at the same time to improve the look of the breast and to match the breasts. This is called oncoplastic surgery. Many breast surgeons can do this without the help of a plastic surgeon. Surgery on the healthy breast may also be suggested so both breasts have a similar appearance.

The techniques discussed below are typically used to shape a new breast.

Implants. A breast implant uses saline-filled or silicone gel-filled forms to reshape the breast. The outside of a saline-filled implant is made up of silicone, and it is filled with sterile saline, which is salt water. Silicone gel-filled implants are filled with silicone instead of saline. They were thought to cause connective tissue disorders, but clear evidence of this has not been found. Before having permanent implants, a woman may temporarily have a tissue expander placed that will create the correct sized pocket for the implant. Talk with your doctor about the benefits and risks of silicone versus saline implants. The lifespan of an implant depends on the woman. However, some women never need to have them replaced. Other important factors to consider when choosing implants include:

Tissue flap procedures. These techniques use muscle and tissue from elsewhere in the body to reshape the breast. Tissue flap surgery may be done with a “pedicle flap,” which means tissue from the back or belly is moved to the chest without cutting the blood vessels. A “free flap” means the blood vessels are cut and the surgeon needs to attach the moved tissue to new blood vessels in the chest. There are several flap procedures:

The DIEP and gluteal free flap procedures are longer procedures and the recovery time is longer. However, the appearance of the breast may be preferred, especially when radiation therapy is part of the treatment plan.

Talk with your doctor for more information about reconstruction options. When considering a plastic surgeon, choose a doctor who has experience with a variety of reconstructive surgeries, including implants and flap procedures, and can discuss the pros and cons of each procedure.

External breast forms (prostheses)

An external breast prosthesis or artificial breast form provides an option for women who plan to delay or not have reconstructive surgery. These can be made of silicone or soft material, and fit into a mastectomy bra. Breast prostheses can be made to provide a good fit and natural appearance for each woman.

Summary of surgical options

To summarize, surgical treatment options include the following:

Women are encouraged to talk with their doctors about which surgical option is right for them. Also, talk with your health care team about the possible side effects from the specific surgery you will have.

More aggressive surgery, such as a mastectomy, is not always better and may cause more complications. The combination of lumpectomy and radiation therapy has a slightly higher risk of the cancer coming back in the same breast or the surrounding area. However, the long-term survival of women who choose lumpectomy is exactly the same as those who have a mastectomy. Even with a mastectomy, not all breast tissue can be removed and there is still a chance of recurrence.

Women with a very high risk of developing a new cancer in the other breast may consider a bilateral mastectomy, meaning both breasts are removed. This includes women with BRCA1 or BRCA2 gene mutations and women with cancer in both breasts. For women not at very high risk of developing a new cancer in the future, having a healthy breast removed in a bilateral mastectomy neither prevents cancer recurrence nor improves a woman’s survival. Although the risk of getting a new cancer in that breast will be lowered, surgery to remove the other breast does not reduce the risk of the original cancer coming back. And more extensive surgery may be linked with a greater risk of problems.

Radiation therapy

Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. There are several different types of radiation therapy:

Although the research results are encouraging, intra-operative radiation therapy and brachytherapy are not widely used. Where available, they may be options for a patient with a small tumor that has not spread to the lymph nodes. Learn more about the basics of radiation therapy.

A radiation therapy regimen, or schedule (see below), usually consists of a specific number of treatments given over a set period of time. Radiation therapy often helps lower the risk of recurrence in the breast. In fact, with modern surgery and radiation therapy, recurrence rates in the breast are now less than 5% in the 10 years after treatment, and survival is the same with lumpectomy or mastectomy. If there is cancer in the lymph nodes under the arm, radiation therapy may also be given to the same side of the neck or underarm near the breast or chest wall.

Radiation therapy may be given after or before surgery:

Very rarely, a small amount of the lung can be affected by the radiation therapy, causing pneumonitis, a radiation-related swelling of the lung tissue. This risk depends on the size of the area that received radiation therapy, and this tends to heal with time.

In the past, with older equipment and radiation therapy techniques, women who received treatment for breast cancer on the left side of the body had a small increase in the long-term risk of heart disease. Modern techniques are now able to spare the vast majority of the heart from the effects of radiation therapy.

Many types of radiation therapy may be available to you with different schedules (see below). Talk with your doctor about the advantages and disadvantages of each option.

Radiation therapy schedule

Radiation therapy is usually given daily for a set number of weeks.

After a lumpectomy. Radiation therapy after a lumpectomy is external-beam radiation therapy given Monday through Friday for 3 to 4 weeks if the cancer is not in the lymph nodes. If the cancer is in the lymph nodes, radiation therapy is given for 5 to 6 weeks. This often starts with radiation therapy to the whole breast, followed by a more focused treatment to where the tumor was located in the breast for the remaining treatments.

This focused part of the treatment, called a boost, is standard for women with invasive breast cancer to reduce the risk of a recurrence in the breast. Women with DCIS may also receive the boost. For women with a low risk of recurrence, the boost may be optional. It is important to discuss this treatment approach with your doctor.

After a mastectomy. For those who need radiation therapy after a mastectomy, it is usually given 5 days a week for 5 to 6 weeks. Radiation therapy can be given before or after reconstructive surgery.
Even shorter schedules have been studied and are in use in some centers, including accelerated partial breast radiation therapy (see below) for 5 days.

These shorter schedules may not be options for women who need radiation therapy after a mastectomy or radiation therapy to their lymph nodes. Also, longer schedules of radiation therapy may be needed for some women with very large breasts. More research is being done to find out whether younger patients or those who need radiation therapy after chemotherapy may be able to have these shorter radiation therapy schedules.

Partial breast irradiation. Partial breast irradiation (PBI) is radiation therapy that is given directly to the tumor area instead of the entire breast. It is more common after a lumpectomy. Targeting radiation directly to the tumor area usually shortens the amount of time that patients need to receive radiation therapy. However, only some patients may be able to have PBI. Although early results have been promising, PBI is still being studied. It is the subject of a large, nationwide clinical trial, and the results on the safety and effectiveness compared with standard radiation therapy are not yet ready. This study will help find out which patients are the most likely to benefit from PBI.

PBI can be done with standard external-beam radiation therapy that is focused on the area where tumor was removed and not on the entire breast. PBI may also be done with brachytherapy by using plastic catheters or a metal wand placed temporarily in the breast. Breast brachytherapy can involve short treatment times, ranging from 1 dose to 1 week. It can also be given as 1 dose in the operating room immediately after the tumor is removed. These forms of focused radiation therapy are currently used only for patients with a smaller, less-aggressive, and lymph node-negative tumor.

Intensity-modulated radiation therapy. Intensity-modulated radiation therapy (IMRT) is a more advanced way to give external-beam radiation therapy to the breast. The intensity of the radiation directed at the breast is varied to better target the tumor, spreading the radiation more evenly throughout the breast. The use of IMRT lessens the radiation dose and may decrease possible damage to nearby organs, such as the heart and lung, and the risks of some immediate side effects, such as peeling of the skin during treatment. This can be especially important for women with medium to large breasts who have a higher risk of side effects, such as peeling and burns, compared with women with smaller breasts. IMRT may also help to lessen the long-term effects on the breast tissue, such as hardness, swelling, or discoloration, that were common with older radiation techniques.

IMRT is not recommended for everyone. Talk with your radiation oncologist to learn more. Special insurance approval may also be needed for coverage for IMRT. It is important to check with your health insurance company before any treatment begins to make sure it is covered.

Proton therapy. Standard radiation therapy for breast cancer uses x-rays, also called photon therapy, to kill cancer cells. Proton therapy is a type of external-beam radiation therapy that uses protons rather than x-rays. At high energy, protons can destroy cancer cells. Protons have different physical properties that may allow the radiation therapy to be more targeted than photon therapy and potentially reduce the radiation dose. The therapy may also reduce the amount of radiation that goes near the heart. Researchers are studying the benefits of proton therapy versus photon therapy in a national clinical trial. Currently, proton therapy is an experimental treatment and may not be widely available or covered by health insurance.

Adjuvant radiation therapy concerns for older patients and/or those with a small tumor

Recent research studies have looked at the possibility of avoiding radiation therapy for women age 70 or older with an ER-positive, early-stage tumor (see Introduction), or for those women with a small tumor. Overall, these studies show that radiation therapy reduces the risk of breast cancer recurrence in the same breast, compared with no radiation therapy. However, radiation therapy does not lengthen women’s lives.

Guidelines from the National Comprehensive Cancer Network (NCCN) continue to recommend radiation therapy as the standard option after lumpectomy. However, they note that women with special situations or a low-risk tumor could reasonably choose not to have radiation therapy and use only systemic therapy (see below) after lumpectomy. This includes women age 70 or older and those with other medical conditions that could limit life expectancy within 5 years. People who choose this option must be willing to accept a modest increase in the risk of the cancer coming back in the breast.

Therapies using medication

Systemic therapy is the use of medication to destroy cancer cells. This type of medication is given through the bloodstream to reach cancer cells throughout the body. Systemic therapies are generally prescribed by a medical oncologist, a doctor who specializes in treating cancer with medication.

Common ways to give systemic therapies include an intravenous (IV) tube placed into a vein using a needle, an injection into a muscle or under the skin, or in a pill or capsule that is swallowed (orally).

The types of systemic therapies used for breast cancer include:

Each of these therapies are discussed below in more detail. A person may receive 1 type of systemic therapy at a time or a combination of systemic therapies given at the same time. They can also be given as part of a treatment plan that includes surgery and/or radiation therapy.

The medications used to treat cancer are continually being evaluated. Talking with your doctor is often the best way to learn about the medications prescribed for you, their purpose, and their potential side effects. It is also important to let your doctor know if you are taking any other prescription or over-the-counter medications or supplements. Herbs, supplements, and other drugs can interact with cancer medications. 


Chemotherapy is the use of drugs to destroy cancer cells, usually by keeping the cancer cells from growing, dividing, and making more cells. It may be given before surgery to shrink a large tumor, make surgery easier, and reduce the risk of recurrence, called neoadjuvant chemotherapy. It may also be given after surgery to reduce the risk of recurrence, called adjuvant chemotherapy.

A chemotherapy regimen, or schedule, usually consists of a combination of drugs given in a specific number of cycles over a set period of time. Chemotherapy may be given on many different schedules depending on what worked best in clinical trials for that specific type of regimen. It may be given once a week, once every 2 weeks, once every 3 weeks, or even once every 4 weeks. There are many types of chemotherapy used to treat breast cancer. Common drugs include:

A patient may receive 1 drug at a time or a combination of different drugs given at the same time. Research has shown that combinations of certain drugs are sometimes more effective than single drugs for adjuvant treatment. The following drugs or combinations of drugs may be used as adjuvant therapy for early-stage and locally advanced breast cancer:

Therapies that target the HER2 receptor may be given with chemotherapy for HER2-positive breast cancer (see Targeted therapy, below). An example is the antibody trastuzumab. Combination regimens for early-stage HER2-positive breast cancer may include:

The side effects of chemotherapy depend on the individual, the drug(s) used, and the schedule and dose used. These side effects can include fatigue, risk of infection, nausea and vomiting, hair loss, loss of appetite, diarrhea, constipation, numbness and tingling, early menopause, weight gain, and chemo-brain. These side effects can often be very successfully prevented or managed during treatment with supportive medications, and they usually go away after treatment is finished. Rarely, long-term side effects may occur, such as heart damage, permanent nerve damage, or secondary cancers such as leukemia and lymphoma. Many patients feel well during chemotherapy and are actively taking care of their families, working, and exercising during treatment, although each person’s experience can be different. Talk with your health care team about the possible side effects of your specific chemotherapy plan.

Hormonal therapy

Hormonal therapy, also called endocrine therapy, is an effective treatment for most tumors that test positive for either estrogen or progesterone receptors (called ER positive or PR positive). This type of tumor uses hormones to fuel its growth. Blocking the hormones can help prevent a cancer recurrence and death from breast cancer when used either by itself or after chemotherapy.

Hormonal therapy may be given before surgery to shrink a tumor, make surgery easier, and lower the risk of recurrence. This is called neoadjuvant hormonal therapy. It may also be given after surgery to reduce the risk of recurrence. This is called adjuvant hormonal therapy.

Types of hormonal therapy

Tamoxifen. Tamoxifen is a drug that blocks estrogen from binding to breast cancer cells. It is effective for lowering the risk of recurrence in the breast that had cancer, the risk of developing cancer in the other breast, and the risk of distant recurrence. Tamoxifen works well in women who have been through menopause and those who have not.

Tamoxifen is a pill that is taken daily by mouth. It is important to discuss any other medications or supplements you take with your doctor, as there are some that may interfere with tamoxifen. Common side effects of tamoxifen include hot flashes as well as vaginal dryness, discharge or bleeding. Very rare risks include a cancer of the lining of the uterus, cataracts, and blood clots. However, tamoxifen may improve bone health and cholesterol levels.

Aromatase inhibitors (AIs). AIs decrease the amount of estrogen made in tissues other than the ovaries in postmenopausal women by blocking the aromatase enzyme. This enzyme changes weak male hormones called androgens into estrogen when the ovaries have stopped making estrogen during menopause. These drugs include anastrozole (Arimidex), exemestane (Aromasin), and letrozole (Femara). All of the AIs are pills taken daily by mouth. Only women who have gone through menopause or who take medicines to stop the ovaries from making estrogen (see Ovarian suppression, below) can take AIs. Treatment with AIs, either as the first hormonal therapy taken or after treatment with tamoxifen, may be more effective than taking only tamoxifen to reduce the risk of recurrence in post-menopausal women.

The side effects of AIs may include muscle and joint pain, hot flashes, vaginal dryness, an increased risk of osteoporosis and broken bones, and increased cholesterol levels. Research shows that all AIs work equally well and have similar side effects. However, women who have undesirable side effects while taking an AI may have fewer side effects with a different AI for unclear reasons.

Women who have not gone through menopause and who are not getting shots to stop the ovaries from working (see below) should not take AIs, as they do not block the effects of estrogen made by the ovaries. Often, doctors will monitor blood estrogen levels in women whose menstrual cycles have recently stopped, or those whose periods stop with chemotherapy, to be sure that the ovaries are no longer producing estrogen.

Ovarian suppression or ablation. Ovarian suppression is the use of drugs to stop the ovaries from producing estrogen. Ovarian ablation is the use of surgery to remove the ovaries. These options may be used in addition to another type of hormonal therapy for women who have not been through menopause.

Hormonal therapy for women after menopause

Women who have gone through menopause and are prescribed hormonal therapy have several options:

In general, women with stage I cancer should expect to take hormonal therapy for 5 years. Women with stage II or III cancer may expect to take it for up to 10 years.

Hormonal therapy for premenopausal women

As noted above, premenopausal women should not take only AIs, as they will not work. Options for adjuvant hormonal therapy for premenopausal women include the following:

Tamoxifen for 5 years. Then, treatment is based on whether or not they have gone through menopause in those 5 years:

Ovarian suppression for 5 years along with additional hormonal therapy, such as tamoxifen or an AI, may be recommended in the following situations, depending on a woman’s age and risk of recurrence:

Ovarian suppression is not recommended in addition to another type of hormonal therapy in the following situations:

Targeted therapy

Targeted therapy is a treatment that targets the cancer’s specific genes, proteins, or the tissue environment that contributes to cancer growth and survival. These treatments are very focused and work differently than chemotherapy. This type of treatment blocks the growth and spread of cancer cells while limiting damage to healthy cells.

Not all tumors have the same targets. To find the most effective treatment, your doctor may run tests to identify the genes, proteins, and other factors in your tumor. In addition, research studies continue to find out more about specific molecular targets and new treatments directed at them. Learn more about the basics of targeted treatments.

The first approved targeted therapies for breast cancer were hormonal therapies. Then, HER2-targeted therapies were approved to treat HER2-positive breast cancer.

HER2-targeted therapy

Talk with your doctor about possible side effects of specific medications and how they can be managed.

Bone modifying drugs

Bone modifying drugs block bone destruction and help strengthen bone. They may be used to prevent cancer from recurring in the bone or to treat cancer that has spread to the bone. Certain types are also used in low doses to prevent and treat osteoporosis. Osteoporosis is the thinning of the bones.

There are 2 types of drugs that block bone destruction:

For people with breast cancer that has not spread, receiving bisphosphonates after breast cancer treatment may help to prevent a recurrence. ASCO recommends zoledronic acid (Reclast, Zometa) or clodronate (multiple brand names) as options to help prevent a bone recurrence for women who have been through menopause. Clodronate is only available outside of the United States. 

Other types of targeted therapy for breast cancer

You may have other targeted therapy options for breast cancer treatment, depending on several factors. Many of the following drugs are used for advanced or metastatic breast cancer.


Immunotherapy, also called biologic therapy, is designed to boost the body’s natural defenses to fight the cancer. It uses materials made either by the body or in a laboratory to improve, target, or restore immune system function.

Different types of immunotherapy can cause different side effects. Common side effects include skin reactions, flu-like symptoms, diarrhea, and weight changes. Talk with your doctor about possible side effects for the immunotherapy recommended for you. 

Systemic therapy concerns for older patients

Age should never be the only factor used to determine treatment options. Systemic treatments, such as chemotherapy, often work as well for older patients as younger patients. However, older patients may be more likely to have side effects that impact their quality of life.

For example, older patients may have a higher risk of developing heart problems from trastuzumab. This is more common for patients who already have heart disease and for those who receive certain combinations of chemotherapy.

It’s important for all patients to talk with their doctors about the systemic therapy options recommended, including the benefits and risks. They should also ask about potential side effects and how they can be managed.

Physical, emotional, and social effects of cancer

Cancer and its treatment cause physical symptoms and side effects, as well as emotional, social, and financial effects. Managing all of these effects is called palliative care or supportive care. It is an important part of your care that is included along with treatments intended to slow, stop, or eliminate the cancer.

Palliative care focuses on improving how you feel during treatment by managing symptoms and supporting patients and their families with other, non-medical needs. Any person, regardless of age or type and stage of cancer, may receive this type of care. And it often works best when it is started right after a cancer diagnosis. People who receive palliative care along with treatment for the cancer often have less severe symptoms, better quality of life, and report they are more satisfied with treatment.

Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, emotional and spiritual support, and other therapies. You may also receive palliative treatments similar to those meant to get rid of the cancer, such as chemotherapy, surgery, or radiation therapy

Research has shown that some integrative or complementary therapies may be helpful to manage symptoms and side effects. Integrative medicine is the combined use of medical treatment for the cancer along with complementary therapies, such as mind-body practices, natural products, and/or lifestyle changes. ASCO agrees with recommendations from the Society for Integrative Oncology on several complementary options to help manage side effects during and after breast cancer treatment. These include:

People may have concerns about if or how their treatment may affect their sexual health and their ability to have children in the future. People are encouraged to talk with the health care team about these topics prior to starting treatment.

Before treatment begins, talk with your doctor about the goals of each treatment in the treatment plan. You should also talk about the possible side effects of the specific treatment plan and palliative care options.

During treatment, your health care team may ask you to answer questions about your symptoms and side effects and to describe each problem. Be sure to tell the health care team if you are experiencing a problem. This helps the health care team treat any symptoms and side effects as quickly as possible. It can also help prevent more serious problems in the future.

Recurrent breast cancer

If the cancer returns after treatment for early-stage disease, it is called recurrent cancer. When breast cancer recurs, it may come back in the following parts of the body:

When breast cancer recurs, a new cycle of testing will begin again to learn as much as possible about the recurrence. Testing may include imaging tests, such as those discussed in the Diagnosis section. In addition, another biopsy may be needed to confirm the breast cancer recurrence and learn about the features of the cancer.

After this testing is done, you and your doctor will talk about the treatment options. The treatment plan may include the treatments described above such as surgery, radiation therapy, chemotherapy, targeted therapy, and hormonal therapy. They may be used in a different combination or given at a different pace. The treatment options for recurrent breast cancer depend on the following factors:

People with recurrent breast cancer often experience emotions such as disbelief or fear. You are encouraged to talk with the health care team about these feelings and ask about support services to help you cope. 

Treatment options for a local or regional breast cancer recurrence

A local or regional recurrence is often manageable and may be curable. The treatment options are explained below:

For women with a local recurrence in the breast after initial treatment with lumpectomy and adjuvant radiation therapy, the recommended treatment is usually a mastectomy. Usually the cancer is completely removed with this treatment.

For women with a local or regional recurrence in the chest wall after an initial mastectomy, surgical removal of the recurrence followed by radiation therapy to the chest wall and lymph nodes is the recommended treatment. However, if radiation therapy has already been given for the initial cancer, this may not be an option. Radiation therapy cannot usually be given at full dose to the same area more than once. Sometimes, systemic therapy is given before surgery to shrink the cancer and make it easier to remove.

Other treatments used to reduce the chance of a future distant recurrence include radiation therapy, chemotherapy, hormonal therapy, and targeted therapy. These are used depending on the tumor and the type of treatment previously received.

Whichever treatment plan you choose, palliative care will be important for relieving symptoms and side effects. Your doctor may suggest clinical trials that are studying new ways to treat this type of recurrent cancer.
