A fine needle biopsy is often not good enough and I had to have a biopsy piece removed under local anaesthetic while the doctor used an ultrasound to pinpoint the exact spots to take it from. The biopsy apparatus can be injected then a spring loaded thing nips a bit off and its done. I had to concentrate not to move and they would warn me when the noise of the thing was going to go off but gosh its hard not to jump. Yes it left some horrific bruises which also made a swelling I had to get the surgeon to check on a week later as it had formed a clot in there. Wait for the pathology to come back before you make your final decision on what surgery to have. It might still be nothing yet. :)
