I've read so much about the CA19-9 markers and still get confused about it. I heard that it could rise after starting chemo or being off it and then back on it…. Has it gone up more than one time?

No, just since finishing radiation/chemo pills. He was wiped out the first 2.5 weeks after rad/onc with a lot of fatigue and brain fog. It finally lifted and he's feeling good. Then, we got the new number, also from a different lab. See doc in a couple weeks and will repeat tests. Possibilities could be bad test, shedding, cancer.
