Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. The breasts may be described as "lumpy" or "doughy". Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. These are normal breast changes, not associated with cancer.

Risk factors include an early age at first menstrual period and either having children at a late age or not at all. It is not a disease but represents normal breast changes. Diagnosis involves ruling out breast cancer. Fibrocystic changes include fibroadenomas, fibrosis, and papillomas of the breast.

Management may involve education about the condition, using a well fitting bra, and pain medication, if needed. Occasionally danazol or tamoxifen may be used for pain. It is estimated that up to 60% of women are affected. Most commonly between the ages of 30 and 50 years.
