Hello, I'm new here but was hoping someone could help me. I am 11 years out from stage 2 breast cancer and I finished 10 years of Tamoxifen in November. Two weeks ago I had my first round of bloodwork since finishing and my CA 27-29 was a 40. I've always been in the 20s and 30s but I've also always been on Tamoxifen. I retested this week and was even higher, at 44. My doctor wants me to go back in 2 weeks for bloodwork one more time and if it's still high he wants to order scans. I can't really even put into words the fear and despair I'm feeling right now, but I'm sure most of you can imagine. So my question is – has anyone had this happen to them, specifically after stopping Tamoxifen, and it NOT progressed to stage 4? I do have a history of ovarian cysts but my markers have always been in normal range.
