Living with Metastatic Breast Cancer

Read our blog, Looking Back Helps Me See the Progress I’ve Made Against Metastatic Breast Cancer.

This section discusses metastatic breast cancer treatment and care.

Metastatic breast cancer (also called stage IV or advanced breast cancer) is not a specific type of breast cancer. It’s the most advanced stage of breast cancer.

Metastatic breast cancer is breast cancer that has spread beyond the breast and nearby lymph nodes to other parts of the body (most often the bones, lungs, liver or brain).

A diagnosis of metastatic breast cancer is devastating. It’s normal to feel overwhelmed and scared. You’re not alone though. It’s estimated there were more than 168,000 women living with metastatic breast cancer in the U.S. in 2020 [1].

It may be helpful to talk with others who have metastatic breast cancer. We have resources for finding a support group (in-person, online and telephone).

Signs and Symptoms of Metastasis

Metastasis is most often found when people report symptoms, such as bone pain, to their health care providers. Based on the symptoms, tests may be done to check if the breast cancer has returned and spread to other organs (metastasized).

Although metastatic breast cancer cannot be cured today, it can be treated. Treatment focuses on extending life and maintaining quality of life. As treatment continues to improve, so does survival.


Emerging Areas in Treatment

Many new drugs to treat metastatic breast cancer are under study.


Clinical Trials

Clinical trials offer the chance to try new treatments and possibly benefit from them. 


Managing Side Effects and Supportive Care

There are many ways to manage side effects caused by metastatic breast cancer treatment and the cancer itself.


Bone Metastases

The bones are one of the most common sites of breast cancer metastases. Bone metastases can damage your bones. Medications to strengthen and protect your bones reduce this damage.


Managing Pain

Controlling pain is a standard part of treatment for metastatic breast cancer. Many methods of pain control are available.


Quality of Life

Quality of life describes your overall well-being. Your emotional and physical health as well as concerns about financial issues can affect your quality of life.



Counseling (either one-on-one or in a group setting) can help improve your mental well-being and quality of life.


Support for Family and Loved Ones

Emotional support is important for those who love and care for someone with metastatic breast cancer.



It’s common to get depressed when living with metastatic breast cancer. Let your health care providers know how you are feeling emotionally. Depression can (and needs to) be treated.


Hospice and End-Of-Life Care

At some point, treatment for metastatic breast cancer may be stopped. This can happen when treatment stops showing any benefit or when it greatly affects quality of life. Reducing symptoms then becomes the focus of care.

Hospice can make this later stage of care as comfortable as possible.
