I have ca 19-9 and ca 15-3 checked as well. Actually, ca 125 was only checked a couple of times initially. The second time, after chemo, ca 125 returned to a normal range and so was never rechecked. I don't know why. But ca 19-9 skyrocketed a few months after chemo and keeps on climbing. Ca 15-3 remains out of bounds too. No one has explained why this is happening, so I've done the research and see that 19-9 especially is also a marker for endometrial cancer. It is usually associated with pancreatic cancer, which I do not, as far as I know, have.
Hope this helps
