A noncancerous breast tumor that most often occurs in young women.


Reproductive hormones may cause fibroadenomas.


A fibroadenoma can be firm, smooth, or rubbery, with a well-defined shape. It's painless and moves easily when touched. Although healthy breast tissue often feels lumpy, a new lump or change in the breasts should be looked at by a doctor.


Treatment may include monitoring for changes in the size or feel, a biopsy to evaluate it, or surgery to remove it.
