Breast Cancer

Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

What is Breast Cancer?

Breast cancer is the most common cancer in the United Kingdom. Every year 48,000 new cases are diagnosed there. Of these, 80% are over 50 but younger women, and in rare cases, men, can also get breast cancer. Breast cancer is the leading cause of death for women aged 34 to 54.
