It is possible for cholestasis to lead to elevated carcinoembryonic antigen.
Carcinoembryonic antigen, a polyglycoprotein complex, is a broad-spectrum tumor marker that can be elevated in a variety of malignant tumors, such as pancreatic, colorectal, gastric, and breast cancers. Its sensitivity and specificity are relatively low.
In addition to malignant tumors, carcinoembryonic antigen can be elevated in many other benign diseases, such as pancreatitis, colitis, bronchial asthma, and liver disease. Cholestasis can cause liver cell damage and may also lead to elevated carcinoembryonic antigen.
Carcinoembryonic antigen, as a tumor marker, only plays an auxiliary role in the diagnosis of malignant tumors, and needs to be combined with imaging manifestations, pathological examinations and other comprehensive judgments. Elevated carcinoembryonic antigen alone can not diagnose malignant tumors, and its elevated level can also be seen in benign diseases. Therefore, it is suggested that patients should not worry too much and go to the hospital as soon as possible to have their conditions evaluated by a professional doctor to decide the next treatment plan.
