For normal people, ca242 is a test to determine whether a normal person has a tumor, mainly for pancreatic and colon cancers.
Ca242 reacts with a protein in cancer to confirm a diagnosis of disease, and is more sensitive and accurate than the traditional ca50, which has been eliminated because of errors in judgment in certain damaging diseases.
After the initial consideration of pancreatic cancer and colon cancer with ca242, imaging tests such as CT and colonoscopy should be performed to clarify the diagnosis and, if necessary, pathology to confirm the final diagnosis, and then treatment should be based on the combined results. Tumor treatment can also be understood by monitoring ca242 during disease treatment and after cure.
