By comparing the 5-year survival rate of tumor patients in the United States, Japan, Britain and China, some people found that “the 5-year survival rate of tumor patients in the United States can reach 81%, and that of Japan and Britain can reach about 65%, while the 5-year survival rate of Chinese herbal medicine in China is only about 25%. Is it because Chinese doctors are not of high standard? No, the surgical level of Chinese doctors is first-class. Is it because China’s medical equipment and drugs are not advanced enough? More than that, a large number of medical equipment and drugs in China are imported and are internationally advanced.” Why is there such a big difference in the five-year survival rate of tumor patients between China and the United States? There is no way to find out whether the statistics are correct or not. But one thing that may be believable is the conclusion that the 5-year survival rate of tumors in China is not very high. Some people believe that the main reasons for the low 5-year survival rate of tumors in China are the misconceptions of clinicians and patients about tumor prevention and treatment in China, inappropriate and simple clinical treatment process as well as excessive abuse, indifferent concept of prevention of tumor recurrence and metastasis, weak anti-recurrence and metastasis treatment measures, and inappropriate use of drugs. Surgery, radiotherapy and chemotherapy, which are the three pillars of cancer treatment, cannot completely solve the problem of recurrence and metastasis at present. At present, in Europe and the United States, “personalized multidisciplinary comprehensive treatment” is commonly adopted in cancer treatment, that is, traditional surgery, radiotherapy and chemotherapy are complemented by minimally invasive ablation and intervention, which is more targeted and directly intervenes in solid tumors, destroying them through heat or chemical tissue coagulants, so that solid tumors can be shrunk and disappear more easily, and the probability of recurrence and metastasis is greatly reduced. The probability of recurrence and metastasis is greatly reduced. Especially for advanced and elderly cancer patients, minimally invasive ablation therapy is used to obtain maximum tumor reduction treatment first, and then supplemented with chemotherapy (drug-targeted), radiotherapy and bioimmunotherapy. As a result, a large percentage of American oncology patients achieve high quality survival with tumor and live beyond five years. It has been said that the best doctor should not only know how to treat, but also know the right time to treat in the right way, but also know when not to treat. This “no treatment” includes no treatment: the disease itself will heal naturally or is not a disease at all; no treatment: treatment will not help the cancer process and will only bring more suffering; and no treatment: the disease is beyond human ability. To be able to tell a patient that no treatment is necessary, the doctor must have a holistic understanding of the disease and must be very knowledgeable in medicine. To be able to tell a patient that no treatment is possible, the doctor must know the limits of medicine as well as acknowledge his or her own limits, which is very difficult. This is because the fundamental purpose of oncology treatment is: the process of getting a high quality of natural life. That is, to live as long as possible under high quality of life conditions to reach their natural life expectancy.
