There are no strategies for complete prevention of central lung cancer. Smoking less, reducing air pollution, and controlling lung infections can help reduce the probability of developing the disease. At present, the causative factors for the development of central lung cancer, as well as all lung cancers of other sites, are not completely clear, and therefore there is no definite strategy for preventing the development of lung cancer. Smoking, air pollution, and long-term lung infections are causative factors in the development of lung cancer, but the exact pathogenesis is not particularly clear. However, cessation of smoking, improvement of air quality, and control of lung infections can reduce the probability of developing lung cancer, but they cannot completely prevent the occurrence of lung cancer. People with high risk factors for lung cancer should be screened for lung cancer, and early detection and treatment are the best treatment measures for lung cancer.
