CA724 is a tumor.

CA724 is a tumor marker commonly used in clinic, CA724 has reference significance in the diagnosis of early gastric cancer and other digestive tract tumors. CA724 is a tumor-associated antigen, but not a tumor-specific antigen, so CA724 is only used as a reference index for tumor diagnosis, and there is no clear regulation at this stage. If CA724 is significantly elevated, it needs to be further combined with endoscopy, imaging and pathology to assist in the diagnosis of tumor.
