CA242 is a tumor marker, not enough to play a role in confirming the diagnosis, when it is greater than 20kU/L consider the possibility of cancer.
At present, CA242 is often recognized as a better tumor marker for judging pancreatic cancer and colon cancer, and its reference value is <20kU/L. However, tumor markers have limitations in confirming the diagnosis of cancer, and its elevated value cannot confirm the diagnosis, and CA242 is especially susceptible to the influence of liver function.
CA242 can be seen in pancreatic cancer, colon cancer, gastric cancer, etc., but benign obstructive jaundice and impaired liver function can often appear false positive results, if you need to confirm the diagnosis, you should also improve the relevant imaging and pathological examination, etc., and actively cooperate with the treatment after the confirmation of the diagnosis.
