At this stage, there are two difficulties in the treatment of lung cancer: first, there are many advanced patients and many occult metastases. The vast majority of patients have advanced lesions and multiple metastases throughout the body at the time of first diagnosis; the remaining patients are difficult to get an accurate disease stage before treatment; in other words, many patients have occult metastases, which are difficult to detect with all current examinations. Second, various treatments have limited efficacy but great side effects. Except for surgery, various commonly used treatments, including chemotherapy, radiotherapy, Chinese herbal medicine, biological immunity, etc., cannot achieve a radical effect; they work for certain patients at certain stages, but it is difficult to determine which patients may benefit from which stages before treatment, while the side effects of these treatments are certain and will certainly cause pain to patients. Surgery, although the most efficacious, has the narrowest scope of application, the highest risks and the greatest limitations. Lung cancer is in fact still an unconquered disease and treatment cannot be summarized by simple effective and ineffective, and many of its approaches are still under constant modification and improvement. There are two issues that must be emphasized in particular Firstly, the prevention and early diagnosis and treatment of cancer. The nation has adapted to the mode of seeing a doctor when there is a disease, not knowing that the prevention and early diagnosis and treatment of cancer are more important, and it is the fundamental part of curing cancer. I suggest to strengthen health investment appropriately, turn seeing a doctor into preventing a disease, and eliminate the possibility of cancer from the source and its deterioration. Secondly, treatment should be moderate and within the limits of one’s ability. Cancer treatment often comes at the cost of huge financial consumption, and its efficacy is often very disappointing, and patients may pour out their family money without seeing how much their lives can be extended. For families with good financial condition, it is necessary to invest; while for families with poor financial condition, it is enough to make the limited money in hand to maximize its effectiveness and achieve no regrets or regrets. Therefore symptomatic treatment is an optional way for the latter, stopping hemoptysis if there is hemoptysis and treating chest tightness if there is chest tightness, so that patients can alleviate their pain is the focus.
