Lung cancer can be diagnosed in a few years.

For lung cancer, if advanced lung cancer is not treated, the median survival time of advanced lung cancer may generally be about 6 to 8 months. With the continuous updating of treatment methods at the current stage, or the organic combination of various treatments, the effective median survival time of chemotherapy alone may be about 12 to 14 months. However, in recent years, with the performance of new treatment methods such as targeted therapy, biological therapy and immunotherapy, the median survival time of advanced lung cancer can reach as long as 30 months, which is obviously the result of medical technology progress in recent years. Of course, for the treatment of advanced lung cancer, it is also necessary to organically combine these treatment methods. It cannot be said that these treatment methods are abused. Sometimes, it is indeed possible to accelerate the death of patients, shorten the survival time of patients, or bring about a certain decline in the quality of life of patients. Therefore, it is recommended that patients receive regular treatment even if they are advanced lung cancer.
