Definitely get a biopsy. I am 32yo and had a so called fibroadenoma too. Even after my surgeon removed it, he said he was confident that is what it was. Mine was not irregular and was encapsulated. Unfortunately, he was wrong. I have no family hx or risk factors, besides birth control use. So, I was completely blown away. Luckily, it was caught early. Most of the time, fibroadenomas are benign. You should get it removed though and get a biopsy just in case. Don't take a chance.
Good luck and hoping for B9 results!!! Read More At : ...
