i had a thin needle aspiration biopsy on breast...surgeon said if it comes back negative i will need to get a differnt type of biopsy
It sounds like your surgeon strongly suspects you have a cancerous tumor and was hoping to get a conclusive diagnosis from the least invasive form of biopsy. However, the fine needle biopsy only sampled a tiny bit of tissue, and the surgeon is concerned that it may have missed cancer cells. Probably the next biopsy would be a surgical biopsy that would take either the entire tumor or a large portion of it. If that one comes back negative, you can breathe a huge sigh of relief. And if it is cancer, you can move quickly to treatment.
