Basic Information About Breast Cancer

Cancer is a disease in which cells in the body grow out of control. Except for skin cancer, breast cancer is the most common cancer in women in the United States. Deaths from breast cancer have declined over time, but remain the second leading cause of cancer death among women overall and the leading cause of cancer death among Hispanic women.

Each year in the United States, about 245,000 cases of breast cancer are diagnosed in women and about 2,200 in men. About 41,000 women and 460 men in the U.S. die each year from breast cancer. Over the last decade, the rate of getting breast cancer has not changed for women overall, but the rate has increased for black women and Asian and Pacific Islander women. Black women have a higher rate of death from breast cancer than white women.
