Fibroadenoma of breast

Description

A benign tumour of the breast characterised by the presence of stromal and epithelial elements. It presents as a painless, solitary, slow growing, firm, and mobile mass. It is the most common benign breast lesion. It usually occurs in women of childbearing age. The majority of fibroadenomas do not recur after complete excision. A slightly increased risk of developing cancer within fibroadenomas or in the breast tissue of patients previously treated for fibroadenomas has been reported.
