Breast Cancer

The Breast Cancer topic includes research on the causes, diagnosis, prevention, and treatment of cancers that originate in the tissues of the breast. Breast cancer happens when cells in the breast grow without control, creating a mass called a tumor that may spread elsewhere in the body. Breast cancer is one of the most common cancer diagnoses in the United States. Anyone with breasts can get breast cancer, but it’s most common in women aged 45 and older.
