Cancer is a condition that results when abnormal cells grow out of control. Anyone can get cancer at any age, but women are at special risk for certain types of cancer.
• Breast – Although it may seem that breast cancer is a gender-specific condition, both men and women can get breast cancer. In women, the cancer usually forms in the ducts or tubes that carry milk to the nipple as well as in the glands that make milk. Aside from skin cancer, breast cancer is the most common cancer in women in the U.S. and it is the second highest cause of cancer deaths among women.
When cancer forms in the breast, it typically creates a tumor that may be felt through the breast tissue. A mammogram can “see” these lumps, sometimes even before they can be felt. Regular breast exams can provide early detection.
