Fibrocystic breast disease, commonly called fibrocystic breasts or fibrocystic change, is a benign (noncancerous) condition in which a woman has painful lumps in her breasts. Fibrocystic breast disease isn’t dangerous, but it can be a bothersome condition because it can cause discomfort. The condition is common. Although it isn’t dangerous to have fibrocystic breasts, this condition can make the detection of breast cancer more challenging.
The exact cause of the condition is not known. Hormones made in the ovaries may make a woman's breasts feel swollen, lumpy, or painful before or during menstruation each month. Up to half of women have this condition at some time during their life. It is most common between the ages of 20 and 45. It is rare in women after menopause, unless they are taking estrogen.
Women who have no symptoms or only mild symptoms do not need treatment. Health provider may recommend the following self-care measures: • Take over-the-counter medicine, such as acetaminophen or ibuprofen for pain
The estimated figures for the prevalence of fibrocystic breast changes in women over lifetime vary widely, with estimates ranging from about 30 to 60 % over about 50 to 60 % to about 60 to 75% of all women.
