31 Days, 31 Things You Didn't Know About Breast Cancer

The term benign breast disease is used to describe a number of benign (non-cancerous) conditions that can affect the breast. Some of the most common benign breast conditions are hyperplasia, cysts, fibroadenomas, and calcifications. Some cause discomfort or pain and require treatment, while others are of little concern and need no medical attention. While benign breast conditions are not cancer, certain types do increase the risk of breast cancer.
