Floral,
I agree with japdip. It is really important to take care of yourself. The surgery is not that invasive and to really be sure it is a fibroadenoma they should biopsy it or remove it. Like Japdip said, the doctor could choose to watch it but you stated it is growing so it would be a good idea to get it removed. Your life is more important than being worried about surgery. If you have a good doctor, you will be in good hands. This is what these people are trained to do.
Take care.
I'm not sure why you think that you can't undergo another surgery to remove the Fibroadenoma; if and when surgery is recommended we really have no choice if we value our health. The only alternative treatment for Fibroadenoma is to just leave them alone which is often done; especially in younger women. I truly think you should try to change your attitude regarding procedures that may be necessary in the future. Regards .....
