As defined by the National Cancer Institute benign breast disease is a common condition marked by benign (non-cancerous) changes in the breast tissue. These changes may include irregular lumps or cysts, breast discomfort, sensitive nipples, and itching. These symptoms may change throughout the menstrual cycle and usually stop after menopause. Benign breast disease is also known as fibrocystic breast disease or mammary dysplasia.
