Causes of high level of lung cancer embryonic antigen

summary

Lung cancer is a kind of terrible malignant tumor. Now more and more middle-aged and old people will suffer from lung cancer. The early treatment effect of lung cancer is better. My uncle was diagnosed with lung cancer some time ago. I'd like to share with you the reasons for the high level of lung cancer antigen.

Causes of high level of lung cancer embryonic antigen

First, carcinoembryonic antigen (CEA) is a component produced by normal embryonic tissue. It generally disappears after birth, or only exists in a very small amount. When the cells become cancerous, the expression of these antigens can increase significantly.

Second: high CEA is not necessarily lung cancer. The normal value of CEA is 0-5ng / ml, which means that CEA is on the high side. Carcinoembryonic antigen can only be used as a reference for the diagnosis of lung cancer. The definite diagnosis of lung cancer should be combined with imaging examination.

Third: when CEA is more than 20ng / ml, most of them indicate digestive tract tumor, so it is not clear that it is lung cancer at this time. In addition, smoking, pregnancy and cardiovascular disease, diabetes, non-specific colitis and other diseases.

matters needing attention

Pay attention to rest, ensure sleep, strengthen exercise to enhance physical fitness. Light, soft and easy to digest diet, avoid spicy, cold, greasy food and alcoholic products, quit smoking. Your CEA is in the normal range. Don't worry. Pay attention to health and check regularly.
