A high non-small cell lung cancer antigen is considered to be non-small cell lung cancer, but it does not necessarily mean that the patient is suffering from this disease, and further examination is needed to confirm the diagnosis. It may also be caused by inflammation in the body. High non-small cell antigen is a clinical value with no practical significance and is only an indicator of lung tumor. If it is persistently elevated, it is important to be alert to the possibility of lung cancer. Therefore, when the antigen of non-small cell lung cancer is detected to be high, it is recommended to go to the hospital for cancer screening to see if there is any abnormal problem, and only after lung cancer is confirmed can surgical treatment be performed. Early surgery can help lung cancer to a certain extent, but if lung cancer is in the middle or late stage, it needs to be treated by radiotherapy or chemotherapy, and surgery is basically unable to achieve good results.
