What are the diagnostic methods for small cell lung cancer

Small cell lung cancer is a common cancer. Now more and more people are suffering from this disease. The probability of men suffering from small cell lung cancer is higher than that of women. It is not terrible to suffer from small cell lung cancer. At this time, you need to pay more attention to your diet, medication, and daily life. Small cell lung cancer is a lesion in the lungs. No matter what disease occurs in the lungs, I believe the patient will be very uncomfortable. Let us now understand the diagnosis method of small cell lung cancer.

Small cell lung cancer is highly malignant, has a short doubling time, and metastasizes early and widely. This type of tumor is very prone to recurrence, so early detection and treatment of this type of tumor is very important. There are many non-invasive examination methods currently, and the most commonly used is the test for the tumor marker CEA. Many patients may go to the hospital for examination, and the doctor will do this test for you. Do you know about CEA? Let's listen to the expert's explanation below.

What is CEA:

Carcinoembryonic antigen (CEA) is a glycoprotein with a MW of 150K-300KD, 45% protein, containing fucose, mannose, galactose and sialic acid. It is mainly found in the epithelial tissue of the fetal digestive tract, pancreas and liver. The CEA content in normal adult serum is extremely low, and it is clinically used to detect the CEA content in serum, which has auxiliary value for the diagnosis of cancer.

CEA test for small cell lung cancer diagnosis:

Analysis of the test results of carcinoembryonic antigen in patients with small cell lung cancer showed that there were statistically significant differences in the CEA positivity rates among patients with the same type of small cell lung cancer, and the CEA positivity rate in patients with extensive small cell lung cancer was significantly higher.

in conclusion:

The CEA test for small cell lung cancer has the advantages of high sensitivity, simple and non-invasive detection method, and can be used as an effective biological indicator for early diagnosis of CEA and post-treatment efficacy.

I believe that now that you know the diagnosis of small cell lung cancer, you should pay more attention to it. If you suffer from this disease, you should seek early treatment to avoid worsening of the disease.
