Featured: Breast Anatomy Main Article

The breast, or mammary gland is made up of lobules, milk producing glands, and a system of ducts to transport milk. Both males and females have breasts. Abnormal enlargement of breasts in men is referred to as gynecomastia. In women, during pregnancy the breasts grow larger and produce milk. Common medical conditions that affect the breasts include breast cancer, breast lumps, fibrocystic changes and cysts, mastitis, and benign tumors (fibroadenomas).
