is not dangerous in and of itself and surgery to remove it is optional, but you may want to have a follow-up ultrasound
to confirm that it is indeed a fibroadenoma and nothing more, particularly if it continues to grow.
Most fibroadenomas are left in situ and monitored by a doctor, or the patient in question. Some are treated by surgical excision. They are removed with a small margin of normal breast tissue if the preoperative clinical investigations are suggestive of the diagnosis. A small amount of normal tissue must be removed in case the lesion turns out to be a phyllodes tumour on microscopic examination.
Because needle biopsy is often a reliable diagnostic investigation, some doctors may decide not to operate to remove the lesion, and instead opt for clinical follow-up to serially observe the lesion over time using clinical examination and mammography
to determine the rate of growth, if any, of the lesion. A growth rate of less than sixteen percent per month in women under fifty years of age, and a growth rate of less than thirteen percent per month in women over fifty years of age have been published as safe growth rates for continued non-operative treatment and clinical observation.
Some fibroadenomas respond to treatment with ormeloxifene
Fibroadenomas have not been shown to recur following complete excision or transform into phyllodes tumours
following partial or incomplete excision.
