Among various types of lung cancer, the occurrence of squamous cell carcinoma and small cell lung cancer is closely related to smoking. Some patients with lung adenocarcinoma are also heavy smokers. These patients with lung adenocarcinoma have the following characteristics: The proportion of sensitive gene mutations in genetic testing is very small, and the more difficult KRAS mutations are more difficult, resulting in poor targeted therapy effects, and immunotherapy effects in some patients are also unsatisfactory. The result is poor treatment effect and short survival time.
It is never too late to quit smoking. One more cigarette will bring more poison to the body.
