Will CEA levels for lung cancer definitely increase?

1. CEA levels may not necessarily rise in lung cancer. If lung cancer is discovered, it is necessary to find out the severity of the disease as soon as possible and receive treatment in time to prevent the spread of cancer.

2. CEA is a tumor marker, mainly produced by cancer cells. Most lung cancer patients will have elevated CEA, because cancer cells will continue to proliferate in lung tissue and produce related tumor markers in the process of stimulating the body. Tumor marker examinations in the human body can be used to assess the risk of cancer, but cannot be used to diagnose cancer.

3. Some lung cancer patients may have normal CEA levels, so this test result is likely that the patient is able to remove the tumor markers themselves. After the tumor markers are produced, the relevant indicators may be at normal levels through testing. At the same time, if the lung cancer itself is not serious and is in the early stages of the disease, the tumor markers are relatively less produced and may not show an increase through the test.

4. Tumor markers are for reference only. If you want to diagnose lung cancer, you need to do a biopsy to make a judgment. Patients also need to maintain a good attitude and treat their condition according to the doctor's prescription.
