Dear retrocath, I am so sorry to hear your news. I was also rediagnosed 6 1/2 years after I thought all was well. But breast cancer came back and went to a spot on my backbone. I also had had regular tests (ultrasounds and mammograms), and they showed no problem. It is so scary and frustrating. When did the cancer start spreading and how would we know without a regular scan? You are on my heart and mind.
