Definition:

Fibroadenoma of the breast is a benign (noncancerous) tumor.

Causes, incidence, and risk factors:

Fibroadenoma is the most common benign tumor of the breast and the most common breast tumor in women less than 30 years of age. Fibroadenomas are usually found as solitary lumps, but about 10-15% of women have multiple lumps that may affect both breasts.

Black women tend to develop fibroadenomas more frequently and at an earlier age than white women. The cause of fibroadenoma is not known.
