Fibroadenoma

Fibroadenomas are common benign breast tumors that may often be too small to feel by hand, yet some may grow to be several inches in diameter. Fibroadenomas are made up of both glandular and stromal (connective) tissues and occur in women ages 20 to 30. The tumors tend to be round and may often feel like a marble within the breast. Fibroadenomas are usually diagnosed by fine needle aspiration or core needle biopsy.

Fibroadenomas often shrink or stop growing without any treatment. If the fibroadenoma increases in size, it usually needs to be surgically removed. Removing the fibroadenoma typically includes removal of some of the surrounding breast tissue. Surgery may cause some scarring that can be seen on future mammograms. In some cases, multiple fibroadenomas are identified.
