I’ve had a fibroadmena removed nearly 2 years ago and have recently found another lump. They gave me mammogram and ultrasound as they couldn’t find lump while examining me. During ultrasound they found another cyst but wanted to drain it as it looked different. She then told me they needed to do a core biopsy as it was not a cyst. The fluid looked clear when I saw the syringe. Dr told me it was 8mm and not to worry as it was so small. But I’m extremely worried as I got mammogram,ultrasound , fna and cnb. I know Dr said not to worry but am worried cos of the fna was not a cyst. What could of shown up on the fna to get a cnb
