This is a benign, firm, rubbery growth that occurs in the breast. It usually occurs during the ages from late teens to the thirties, but can occur later. There is no connection between a fibroadenoma of the breast and a fibroid tumor of the uterus.

Fibroadenomas of the breast are usually single. Having one fibroadenoma does not mean that you will have other fibroadenomas, although it is possible.

Fibroadenomas have no relationship to breast cancer other than the fact that we have to biopsy the fibroadenoma to make sure that it is not cancer. Fibroadenomas do not cause cancer or turn into cancer. We often don't know that a lump is a fibroadenoma until after it is biopsied. 

All women should perform a monthly Breast Self Exam (BSE). Having a benign fibroadenoma does not change this. Any changes or new lumps should be brought to the attention of a physician.
