How to check lung tumor markers

These tumor markers can be used for lung tumor screening, which needs to be judged in combination with lung imaging examination. Generally, lung ct is one of the preferred examination methods. If blood tumor markers are significantly higher than normal, you should be alert to the possibility of lung cancer. If necessary, a needle biopsy or bronchoscopy of the lung tumor should be performed.
