You are welcome. Please follow your instinct. An ultrasound is so easy and a safe way to pick up on abnormality. Make sure when you get the results from your GP that he reads through it all an not just the top bit. If at any stage of the report the words FNA comes up then insist you want an FNA (Fine Needle Biopsy). My cyst was ultrasound tested and the results say benign cyst but patient could have FNA if she wanted. My GP never read that last bit, he only said "just benign cyst", 12 months later it turned out is was a very aggressive cancer that by then had spread to my lymph nodes. If I had known there was a test like an FNA I would have opted to have it. You need to take charge sometimes and read the results and educate yourself on terminology etc so you know what they are talking about. An ultrasound is super easy and quick and the most reliable test to check what is going on in your breasts. Keep us posted how you go. Good luck x
