What is the reason for CEA Determination

summary

Carcinoembryonic antigen (CEA) is a glycoprotein that can be produced by Dachang cancer tissue. As an antigen, the patient's cotton padded coat reflects a situation. Such a situation is called CEA. CEA mainly exists in the digestive system cancer originated from endoderm, and aipai antigen also exists in the digestive tract tissue of normal embryo. When there is information about this case, it can also be found in normal human serum The presence of trace CEA. In life, you may encounter the situation of high antigen, which needs our attention. Now let's understand the reasons for CEA Determination.

What is the reason for CEA Determination

Reason 1: liver disease experts point out that many people think that carcinoembryonic antigen is carcinoembryonic antigen of liver cancer. It is unscientific to be familiar with it. Carcinoembryonic antigen is carcinoembryonic antigen, not carcinoembryonic antigen of liver cancer. The specific index of liver cancer is called alpha fetoprotein. In fact, carcinoembryonic antigen has a normal reference value, as long as it is within the normal range, there is no problem.

Reason 2: the normal reference value of carcinoembryonic antigen is that the concentration of carcinoembryonic antigen in normal human body is less than 2.5ng/ml, and the concentration of carcinoembryonic antigen is more than 20ng / ml, which indicates that there is a tumor. Carcinoembryonic antigen elevation is mainly seen in stomach, intestine and other digestive tract tumor diseases. If the index is higher than this range in the re examination, we should pay attention to it.

The third reason: the reason of the increase of CEA is common in colorectal cancer, pancreatic cancer, gastric cancer, small cell lung cancer, breast cancer, medullary thyroid cancer and other such cancers. In addition, smoking, pregnancy, cardiovascular disease and diabetes may also cause the rise of CEA. Patients with elevated CEA must pay more attention to it.

matters needing attention

Carcinoembryonic antigen elevation must cause the patient's high attention, should go to the hospital in time to see a doctor, only in the hospital after the doctor's guidance and comprehensive examination, it is possible to guide the root cause, suit the medicine to the case, timely treatment, in addition, in ordinary life, also should pay attention to the healthy law of living habits, less smoking and drinking, do some good things for the body Love.
