Understanding Stage 4 Breast Cancer

Breast cancer develops in “stages,” from 0 (noninvasive) to 4 (advanced). Stage 4 breast cancer has either come back or spread to other parts of the body. Some common areas where breast cancer might spread include the bones, brain, liver, and lungs. Once it reaches stage 4, the cancer is considered to be incurable, although there are many treatment options available. Many women are now able to live with stage 4 breast cancer as a chronic condition.
