Lung cancer is the leading cause of cancer‐related death worldwide. In China, the incidence of lung cancer has grown rapidly, resulting in a large social and economic burden. Several researchers have devoted their studies to lung cancer and have demonstrated that there are many risk factors for lung cancer in China, including tobacco use, environmental pollution, food, genetics, and chronic obstructive pulmonary disease. However, the lung cancer incidence is still growing rapidly in China, and there is an even higher incidence among the younger generation. One explanation may be the triple‐neglect situation, in which medical policies that neglect prevention, diagnosis, and supportive care have increased patients' mortality and reduced their quality of life. Therefore, it is necessary to enhance the efficiency of prevention and early diagnosis not only by focusing more attention on treatment but also by drawing more attention to supportive care for patients with lung cancer.

Numerous investigators have devoted their research to lung cancer and have demonstrated that China has the highest number of risk factors worldwide, including tobacco use, environmental pollution, food, genetics, and chronic obstructive pulmonary disease. In addition, the incidence of lung cancer is still growing rapidly, and it is greater in the younger generation.
