I had a large cyst on left breast aspirated, I was then told I had thickening on right breast and possibly calcification, I went back 1 week later and had 2 core biopsies done, had 2 markers put in,  all came back clear and it was just fibrous tissue, but wanted to do a vacuum core biopsy, 4th Jan, talk about take forever and uncomfortable to the point it was painful. The biopsy took out a marker which they replaced, 3/4 times the needle went in which was the thickness of a pen. I was told I'd be bruised again, my breast went from red, purple, black brown green and yellow, 3 months on I still have a shadow bruise on part of my breast and a dip, where the biopsies where taken, I occasionally get pain in the breast, results where all fine and clear, but it worries me why I keep getting sharp pains, no lumps, going from my breast into before my armpit.
