Hi @amanda88, Sometimes cancer markers do not accurately reflect what is going on in terms of the disease. Has you mother's oncologist relied on them before? I know mine aren't really reflective of what is going on and my oncologist relies on PET and CT scans even though I still get CA153 blood tests. Unfortunately, my guess is that your mum's oncologist will rely on the CT scans (rather than the cancer markers) and may what to change treatments either now or soon. I hope this is not the case. Good luck. Cheers Lisa
