High CA242 can be seen in malignant diseases such as pancreatic cancer and benign diseases such as gastritis, requiring further examination.
CA242, or cancer antigen 242, is a tumor screening marker currently used in clinical practice, and its normal reference value is <20 kU/L. High CA242 can be seen in malignant tumors of the digestive system, such as pancreatic, colon, and gastric cancers, as well as in ovarian, uterine, and lung cancers.
In addition to the above malignant tumors, CA242 can also be elevated in some non-malignant diseases such as gastritis, cholangitis, cholecystitis, pancreatitis or colitis.
Therefore, CA242 needs to be combined with the results of imaging and pathology to identify the specific cause. It is recommended to consult a doctor in time for standardized diagnosis and treatment.
