Generalized breast lumpiness, also called fibrocystic breast changes or benign (noncancerous) breast disease, is a common breast condition. Generalized breast lumpiness tends to become more noticeable before a menstrual period and can often be felt in both breasts around the nipple and in the upper, outer part of the breasts.

Generalized breast lumpiness occurs most often in women ages 35 to 50. It usually disappears with menopause, when menstrual periods end. It may continue in women who are taking estrogen for hormone therapy.
