Left lobe cancer symptoms?

1. Cough: it is the first common symptom of lung cancer, especially the central type. Cough of lung cancer is characterized by choking, no sputum or only a small amount of white foam like sticky sputum. If it grows near the common bronchus or protuberance, the choking cough is more severe, and antitussive drugs are not easy to control. The tumor grows on the small bronchial mucosa and may have no or little cough. Cough of lung cancer is often covered by chronic bronchitis or cigarette cough. If the nature or regularity of cough suddenly changes, we should be alert to the possibility of lung cancer.

2. Hemoptysis or hemoptysis sputum: hemoptysis is a common symptom of lung cancer, mainly growing in the bronchial mucosa of the tumor surface ulceration and bleeding, common in central lung cancer. It is characterized by intermittent small amount of blood sputum, blood more than sputum, and fresh, massive hemoptysis is rare. The duration of hemoptysis varies from one to several days, which can disappear without treatment. The elderly can be up to several months. Although it is difficult to stop bleeding after treatment, it is mainly caused by central necrosis, dissolution and bleeding of peripheral lung cancer.

3. Fever: many patients find lung cancer only because of recurrent fever, self-made cold or bronchitis. Another half of the patients are diagnosed with bronchial infection or segmental pneumonia first. After treatment, the symptoms are improved, but the focus absorption is not complete, or it appears repeatedly, and the diagnosis is clear only after comprehensive examination. The causes of fever are bronchial obstruction, retention of inflammatory excreta and infection; The other is cancerous fever, which is caused by the release of pyrogen by the tumor itself, or by the stimulation of the body temperature center by metabolites. The former is effective by anti infection treatment, while the latter needs indomethacin and corticosteroids to reduce fever.
