About the Disease

What is Metastatic Breast Cancer

Understanding The Disease

Breast cancer is described in different stages. The stages are determined by the size of the tumor and if it has spread to a certain number of lymph nodes or other areas of the body.

Metastatic breast cancer, also known as stage IV breast cancer, can be any size and occurs when cancer has spread outside the breast and nearby lymph nodes to other parts of the body, such as the lungs, bones, liver, or brain.

There is currently no cure for metastatic breast cancer, but there are treatments that can shrink the cancer or slow its progress for some time.
