What is Breast Cancer?

Breast cancer is cancer arising in breast tissue. Cancer is simply a group of abnormal cells that have abnormal growth patterns.
Although breast cancer is primarily a disease of women, about 1% of breast cancers occur in men.

In 2005, the American Cancer Society estimated that 212,930 new cases of breast cancer would be diagnosed in the United States.

When the cancer is at it's worst state, a doctor may have no choice but to perform a mastectomy, removal of the breast(s).
