Lung cancer is a malignant tumor of the respiratory system. The symptoms of early lung cancer are very similar to those of respiratory diseases, which often lead to misdiagnosis. What are the common diagnostic methods for lung cancer ? Here are some common diagnostic methods for lung cancer.

In general, the common diagnosis methods for lung cancer are:

1. If you have persistent coughing for unknown reasons and repeated blood in your sputum, you should be alert, especially men over 40 years old.

2. Patients with chronic cough in the past, whose cough has changed recently, and those with repeated localized lung inflammation. This is the common basis for the diagnosis of lung cancer.

3. People who have been smoking for a long time, have chronic coughs, have a family history of cancer, and have a long-term contact history with certain harmful substances should be regarded as key subjects for regular examinations.

4. For some extrapulmonary manifestations such as cachexia, proliferative arthropathy and clubbing of fingers (toes), myasthenic syndrome, peripheral neuritis, dermatomyositis, acanthosis nigricans, etc., if the above conditions occur, attention should be paid to the diagnosis of lung cancer.

5. Patients with pulmonary tuberculosis who have not responded to anti-tuberculosis treatment or whose lesions have improved after treatment but new lesions have appeared should undergo further examination to confirm the diagnosis of lung cancer.

The above is a common diagnosis method for lung cancer. I believe everyone has some understanding of this. Once diagnosed with lung cancer, you must go to the hospital for treatment immediately to avoid missing the best time for treatment.
