Solitary lumps and cysts
Benign breast conditions also include several types of distinct, solitary lumps. Such lumps, which can appear at any time, may be large or small, soft or rubbery, fluid-filled or solid.
Cysts are fluid-filled sacs. They occur most often in women ages 35 to 50, and they often enlarge and become tender and painful just before the menstrual period. They are usually found in both breasts. Some cysts are so small they cannot be felt; rarely, cysts may be several inches across. Cysts are usually treated by observation or by fine needle aspiration. They show up clearly on ultrasound.
