The spreading of the cancer metastasizes in the body when cancer cells either invade nearby healthy cells, penetrate into the circulatory or lymph system, migrate through circulation, lodge in capillaries, or when new small tumors grow.
African American women are less likely to develop breast cancer, but when they do, they are more likely to be diagnosed with a late-stage breast cancer such as metastatic breast cancer and have a decreased survival rate compared to white women. However, a new study finds the number of U.S. women living [longer] with the most advanced stage of breast cancer has been rising since the 1990s.
