I had one about 3.5 years ago. I was referred to a breast surgeon (oncologist) and had it removed within a few weeks (maybe a month) of me finding it. It was a relatively simple out-patient procedure. He told me that fibroadenomas are generally harmless, but that hormones can make them grow OUT OF CONTROL -- especially during pregnancy -- so it was better to get it removed. It was also nice to get the lab test they did on it after it was removed which gave me a 100% comfirmation.
