Is surgical removal necessary for fibroadenomas?

No: Fibroadenomas are the most common benign tumors of the breast. Diagnosis is usually made by sampling a piece of the lump obtained by needle biopsy. If the lump does not cause pain, is not very large, and is not growing, it is acceptable to watch these.

Rarely: Fibroadenomas are benign and by natural history will often regress over 10-15 years. diangosis can be established via core bx. Making them "go away" is generally reserved for symptomatic (palpable and/or tenderness which is usually cyclical). Minimally invasive options are generally preferred over surgical excision - image guided percutaneous vacuum assisted excision, cryoablation.
