== Study Questions ==
* <spoiler text="At what age do fibroadenomas usually occur?">They occur at any age within the reproductive period of life, but they are somewhat more common before age 30.</spoiler>
* <spoiler text="Why do fibroadenomas cause problems in pre-menopausal women?">The epithelium of the fibroadenoma is responsive to hormones. Slight increases in size may occur during the late phases of each menstrual cycle, and pregnancy may stimulate growth and lactation. Postmenopausally, regression or calcification may result. There is also a slightly increased risk for development of breast carcinoma.</spoiler>
