Most breast lumps are benign (non-cancerous), as in fibroadenoma, a
condition that mostly affects women under age 30. Fibrocystic
breast changes occur in more than 60% of all women. Fibrocystic
breast cysts change in size with the menstrual cycle, whereas a
lump from fibroadenoma does not. While most breast lumps are
benign, it is important to identify those that are not. See your
health care provider if a lump is new, persistent, growing, hard,
immobile, or causing skin deformities.
