What are the early symptoms of lung cancer? What causes lung cancer?

The early symptoms of lung cancer are atypical and easily overlooked. Cough is one of the early symptoms of lung cancer, which is characterized by paroxysmal irritating choking, unclean feeling, generally no sputum or only a small amount of white foam sputum, and purulent sputum may appear when secondary infection occurs. If there is no improvement after 2 weeks of anti-inflammatory treatment, we should be alert to the possibility of lung cancer. Or the nature of cough has changed on the basis of the original chronic cough, even accompanied by "tracheal sound" and "shortness of breath", which should be paid attention to. Another warning sign of lung cancer is intermittent repeated small amount of blood sputum, or bloodshot sputum. In addition, there are symptoms such as chest pain, chest tightness and fever. When these symptoms appear, patients should go to the hospital for examination as soon as possible. Chest CT has a good ability to distinguish most lung diseases. Further diagnosis requires bronchoscopy, puncture, biopsy and thoracotomy according to the lesions and patients' conditions to find out the pathological types of cancer cells.

At present, smoking is the main cause of lung cancer. If you smoke less, you will stay away from lung cancer.
