The reason why non-small cell lung cancer antigen is high

Non-small cell lung cancer antigen (Cyfra21_1) is the most valuable serum tumor marker for non-small cell lung cancer, with a specificity of 87%. Non-small cell lung cancer antigen is particularly important for early diagnosis, efficacy observation, and prognosis monitoring of lung squamous cell carcinoma.

However, a high level of non-small cell lung cancer antigen does not mean anything. You should consult your attending physician for details.

Moreover, a high value may be affected by inflammation, so a detailed examination is still required. There are several main methods for lung cancer examination: 1. Chest fluoroscopy and radiography 2. Repeated examination of sputum for cancer cells can obtain positive results, which is of diagnostic value. 3. Bronchoscopy 4. For those with accurate lung puncture positioning, smear examination of the puncture material can generally obtain positive results, which is of diagnostic value. 5. Superficial lymph node puncture or biopsy.

If lung cancer is confirmed, timely treatment is required to inhibit the proliferation of cancer cells and control the metastasis of lung cancer cells in order to gain time for treatment.
