What Is Breast Cancer?

Breast cancer occurs when abnormal cells grow out-of-control in one or both breasts. They can invade nearby tissues and form a mass, called a malignant tumor. The cancer cells can spread (metastasize) to the lymph nodes and other parts of the body.

Breast cancer is many women's worst fear. But experts have made great progress in treating cancer. If it is found early, breast cancer can often be successfully treated, and it is not always necessary to remove the breast.
