This page has a brief amount of info about breast fibroid adenomas, or fibroadenomas: Hmmm, after reading a couple dozen pages on the web, it's starting to seem like I should call the surgeon back and ask for a needle biopsy after all. It's always the bad stuff that's posted on the web, eh?
But I'm still not losing sleep over it. In any event, I already have a 3-month followup appointment. Also standard procedure from my previous experiences.
