Nowadays, once people find out they have a tumor, they often think of surgery, chemotherapy, radiotherapy, etc., and use all means to deal with the tumor to “kill” all cancer cells. However, people are also paying a heavy price for their rashness and recklessness. Many patients with mid- to late-stage tumors not only fail to prolong their lives after over-treatment, but also spend their remaining days in great pain, and many of them even walk into the hospital and carry themselves out of the hospital without realizing that they are not dying from tumors until the last moment of their lives. At the same time, in order to save the life, some patients’ families are willing to spend all their money, and finally the patients leave with a sense of guilt, leaving a heavy financial burden to their loved ones. At the same time, we should also see that there are thousands of tumor patients in the clinic, and many “cancer stars” emerged, who can’t say that there is no more cancer in their body, maybe the examination suggests that there is still tumor in their body, but it is very stable for many years and no obvious progress. At the same time, their quality of life and survival is very good and they are living happily! Can we say that this is not a great success? As mentioned earlier, in 2006, WHO has started to change the concept of defining malignant tumor as a chronic disease that can be treated, controlled and even cured like hypertension and diabetes mellitus. If diabetes can survive with the disease and hypertension can be controlled by taking medicine every day, why can’t tumor patients survive with the disease? In recent years, with medical advances, people have been able to monitor prostate cancer early by testing for PSA, and as a result, considerably more patients have been operated on. However, a report was published in the United States not long ago, stating that for patients with early stage prostate cancer, the five-year survival rate is the same for those treated and those not treated. It is a very important direction for future TCM cancer research to let patients with advanced tumors “survive with tumors”. The Chinese Academy of Engineering and the President of the Chinese Medical Association, Zhong Nanshan, said while citing the different treatment concepts of Chinese and Western medicine for tumors, “Western medicine used to simply kill the tumor, and finally found that the tumor was gone and the person died; Chinese medicine does not directly destroy the tumor, but proposes to ‘attack the evil with the good’ and ‘co-exist with the tumor’. Chinese medicine does not destroy the tumor directly, but proposes to ‘attack the evil with the good’ and ‘co-exist with the tumor’ to improve the patient’s quality of life and prolong life. Now the whole world’s treatment philosophy for tumors is also changing to this aspect”. In recent years, the starting point of developing anti-tumor drugs has also undergone an obvious change, from the previous enthusiasm to reduce cancer cells to inhibit the growth of cancer cells, among which the targeted drugs in medical oncology have emerged, through precise targeted therapy, accurately acting on cancer cells, blocking tumor growth channels, inhibiting the proliferation of cancer cells, reducing the damage to the body, allowing patients to stabilize their condition without affecting the quality of life. It allows patients to stabilize their disease for a longer period of time without affecting their quality of life, and live as many patients with chronic diseases, achieving survival with tumor. Therefore, if it is impossible to remove tumor, we might as well treat it as a friend that we must accept, study, analyze and master its rules, and find ways to live in harmony with it to achieve long-term coexistence. Therefore, the treatment of tumor is not a duel of “either you die or I die”, and long-term coexistence with tumor is also a strategy. The theoretical basis of modern medical treatment is direct “confrontation”, which is the inhibition and interruption of life phenomena, such as bacterial infection, we should use antibiotics to “sterilize”, and tumor, we should try to “eradicate”. For example, if you have a bacterial infection, you should use antibiotics to “sterilize” it, and if you have a tumor, you should try to “eradicate” it. However, in Chinese medicine, the emphasis is on “harmony between yin and yang” and “harmony between heaven and man”, and the same bacterial infection does not emphasize on elimination, but on control and restoration of harmony with man. Clinical research also confirms that bacteria and our body co-exist and depend on each other. If broad-spectrum antibiotics are used indiscriminately, it will bring new problems due to dysbiosis. Since tumor is a concomitant product of aging, if it cannot be avoided, then why not learn from the wisdom of our ancestors, “you live and I live”, so that “all things nurture and do not harm each other”, “and all things float and sink in the door of growth “.
