@heavyphil Actually, they do have a PSA-like test for pancreatic cancer - it’s called a CA19-9 blood test. The CA 19-9 test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in a sample of blood. CA 19-9 is a type of tumor marker. But, just as with PSA blood tests - elevated CA19-9 levels could be caused by many other things - so they don’t routinely offer it.

(I found out about it when my brother was diagnosed with pancreatic cancer. Normal levels are < 37 u/mL; his was 1,864 u/mL. I asked the doctor about that; he said that’s one marker for pancreatic cancer, and they also use it as a follow-up to gauge how treatments are going, and if there is a recurrence. I’m thinking…..that’s just like PSA testing.)

BTW, they also have a PSA-like test for ovarian cancer - it’s called the CA-125 blood test. Similarly, it measures levels of the CA 125 protein, primarily used to help diagnose, monitor treatment, or check for recurrence in ovarian cancer. (Comparable to how a PSA test measures levels of the PSA protein, primarily used to “help diagnose, monitor treatment, or check for recurrence” in prostate cancer.)

But, just like with a PSA test where many things can cause PSA to rise, many things can cause a CA125 to rise so, the test isn’t offered as a standard test.

If women asked for the CA125 test at about 45y/o (just as PSA tests are recommended for men starting at about 45y/o), there might be earlier detection of that cancer as well.

Amazing how much there is out there that we simply don’t hear about!
