Fibroadenomas (fi-bro-ad-uh-NO-muhz) are solid, noncancerous tumors that often occur in women during their reproductive years. A fibroadenoma is a firm, smooth, rubbery or hard lump with a well-defined shape. It moves easily under your skin when touched and is usually painless. Fibroadenomas are more common among women in their 20s and 30s.
Fibroadenomas are one of the most common breast lumps in premenopausal women. Fibroadenomas range in size from less than 1 centimeter to several centimeters in diameter. They can get bigger during pregnancy and breast-feeding.
Treatment may include careful monitoring to detect changes in the size or feel of the fibroadenoma or surgery to remove it.
