Breast cancer treatment

The goal of treating early and locally-advanced breast cancers (stages I, II and III) is to get rid of the cancer and keep it from coming back.

Treatment includes some combination of:

These treatments are designed to remove the cancer from the breast and destroy any cancer that might still be in the body.

Your breast cancer treatment plan

Your breast cancer treatment plan is based on both medical and personal choices.

Together, you and your health care provider make breast cancer treatment decisions. After you get a recommended treatment plan from your provider, take time to study your treatment options and make thoughtful, informed decisions. Each treatment option has risks and benefits to consider along with your own values and lifestyle.

Your treatment is tailored to:

  • Your specific breast cancer (the biology of the tumor)
  • The stage of the breast cancer
  • Your overall health, age and other medical issues
  • Your personal preferences

Because of the differences between tumors and between people, your treatment plan may differ from another’s, even though you both have breast cancer.

Breast cancer treatment can be divided into local and systemic therapy.

Local therapy

Local therapy removes the cancer from a limited (local) area, such as the breast, chest wall or lymph nodes in the underarm area.

It also helps ensure the cancer doesn’t come back in that area.

Local therapy involves surgery, with or without radiation therapy to the breast area.

Systemic therapy (adjuvant therapy)

The goal of systemic therapy is to get rid of cancer cells that may have spread from the breast to other parts of the body. These cells are too small to see on scans or to measure with lab tests.

Systemic therapy uses drug therapies that travel throughout the body to get rid of cancer cells. It includes chemotherapy, hormone therapy and targeted therapy.

Some drug therapies are given by vein (through an IV) and others are given in pill form.

Because systemic therapy is used in addition to (an adjunct to) breast surgery, these treatments are often called adjuvant therapy.

Learn about factors that affect treatment options.

Managing side effects (palliative care) and supportive care

Managing side effects and supportive care are important parts of breast cancer treatment. 

  • Palliative care aims to prevent or relieve side effects (such as pain or nausea).
  • Supportive care includes palliative care as well as care of your emotional, social, spiritual and practical needs.

How age affects your treatment plan

No matter your age, your treatment plan depends on many factors, such as tumor stage, tumor grade, hormone receptor status and HER2 status

Your overall health and other health conditions also play a role.

For example, if you have heart disease, some medications used to treat breast cancer can do more harm than good.

All of these things, as well as your age, are considered when planning your treatment.

Young women

Young women with breast cancer may have special concerns about early menopause and loss of fertility due to treatment.

Learn about these issues for young women with breast cancer.

Your health care team

Throughout your treatment and beyond, you will get care from many health care providers. 

Your health care team may include: 

  • Physicians involved in cancer treatment (oncologists, surgeons, radiation oncologists)
  • Physicians involved in other care for people with breast cancer (radiologistspathologists, genetic counselors and others)
  • Nurses
  • Dietitians
  • Social workers
  • Physical therapists
  • Palliative care or pain specialists
  • Patient navigators
  • Pharmacists
  • Other providers

These professionals may be involved in your care during diagnosis, treatment and recovery.

Learn about choosing a physician.

Staying organized

It may be helpful to use a notebook, 3-ring binder or other organizer to keep track of your breast cancer treatments and health care team.

You may want to include:

  • A directory of the names, addresses and contact information for your health care team
  • Insurance information
  • Medication lists
  • Pharmacy contact information
  • Other medical information
  • A calendar to help plan and keep track of appointments
  • Blank paper to write down questions and answers or to record any side effects you are having or other information for your health care team
  • Pockets to store materials  


The importance of following your breast cancer treatment plan

Completing your breast cancer treatment plan (called adherence or compliance) is very important. People who complete the full course of treatment have a higher chance of survival.

Sometimes completing your treatment plan may be hard, but there are things you can do to make it easier.

First, tell your health care provider right away if you have any side effects. Your provider may be able to help. Having fewer side effects can help you complete your treatment plan.

Sticking to your treatment plan can be very hard for long-term treatments, such as hormone therapy.

Planning ahead can help you juggle your treatment and daily life. For example, if you have trouble remembering to take your medicine, a daily pillbox or setting an alarm on your watch or mobile device (you may be able to download an app) may help [1].

Insurance issues and financial assistance

Insurance issues (such as what to do if a claim is denied) can be a major concern while you are being treated for breast cancer.

Paying for medications and other out-of-pocket expenses can also be a burden.

Learn about insurance and financial assistance programs.

Transportation, lodging, child care and elder care assistance

If you need help getting to and from treatments or if you (or your family) need a place to stay overnight while getting treatment, there are programs that can help.

There are also programs to help with the cost of child care and elder care while you are undergoing treatment.
