I had gripping pains prior to being diagnosed as well as while waiting on surgery. I had it once since surgery and they did an ultrasound that didn't show any issues. I had one implant due to a childhood issue and had it leak, the second one was "recalled" because it could cause lymphoma. Now, I read that they say they all can cause cancer. When I asked to have mine removed while they were doing the mastectomy on the other side, my dr said that I made a good call because I had cells that had the potential of turning to cancer.
