Not to scare you, but I was misdiagnosed with a lactating adenoma just before my last pregnancy and it turned out to be Stage III breast cancer and I was 8 weeks pregnant.
With that said, yours might indeed be a fibroadenoma, but the only definitive way to tell is to do a biopsy and soon. That will be the only way to alleviate any fears you might have.
I hope that you have just a fibroadenoma and nothing more. If you have something more, feel free to contact me. Been there, done that. Got my babies and life is still good.
Good Luck!

Dear ani, A fibroadenoma is a benign growth. Fibrooadenomas are distinct on a mammogram or ultrasound and when aspirated - no fluid comes out. As long as the doctor is sure it is a fibroadenoma, there is no need to remove the lump. In 50% of the cases fibroadenomas will go away on their own within 5 years. In others, the life of a fibroadenoma is about 15 years. In teenagers - the tendency is not to remove fibroadenomas. In middle age women, the tendency is to remove the fibroadenomas to be sure they are, in fact, fibroadenomas.
