What is the normal value of CEA

summary

Carcinoembryonic antigen is a tumor marker, therefore, in the corresponding examination of people's body, we should pay more attention to the normal value range of carcinoembryonic antigen. Here we will understand the normal value of carcinoembryonic antigen.

What is the normal value of CEA

Firstly, CEA is a kind of proteoglycan complex in colon cancer, normal embryo intestine, pancreas and liver. It can be widely found in the digestive system cancer originated from endoderm, in the digestive tract tissue of normal embryo, and in the serum of normal people.

Secondly, carcinoembryonic antigen (CEA) is an auxiliary diagnostic index for gastrointestinal tumors. Normal value ≤ 5ng / ml, CEA was initially found in colon cancer and fetal intestinal tissue, so it was named carcinoembryonic antigen.

Finally, the increase of CEA is common in colorectal cancer, pancreatic cancer, gastric cancer, small cell lung cancer, breast cancer, medullary thyroid cancer and so on. However, the high level of carcinoembryonic antigen often appears in other diseases. Therefore, carcinoembryonic antigen has a certain value in the diagnosis of tumors.

matters needing attention

In the normal range of carcinoembryonic antigen have a general understanding, we should pay attention to eat more anti-cancer food in weekdays.
