It is a fundamental change in the concept of cancer treatment in modern medicine to allow cancer patients to “peacefully coexist” with cancer. Generally speaking, when cancer is in the stable stage, that is, when the tumor in human body stops growing or grows slowly, cancer patients and tumors can “peacefully coexist” and give up the original tactic of “war of annihilation” and fight a “tug-of-war” with cancer mainly to improve their own immunity. The tumor and the cancer patient can “peacefully coexist” and give up the original tactic of “war of annihilation” and fight a “tug-of-war” with the cancer mainly to improve their immunity. In most people’s mind, they think that the only way to recover from cancer is to have surgery to remove the tumor or use radiotherapy or chemotherapy to kill the cancer cells completely. It can be said that this is the hope of every cancer patient and family members. In fact, the treatment of cancer should be properly understood, and the treatment method should be determined according to the disease, not as simple as some people think. In early stage, surgery, radiotherapy or chemotherapy can be used. If the patient is in advanced stage and has metastasis, it is no longer suitable for surgery. If surgery is necessary, it will not only fail to achieve the treatment effect, but also increase the patient’s pain and reduce the quality of survival. Therefore, different symptomatic treatments should be applied to patients with advanced cancer to improve their symptoms and reduce their pain, so that they can “live peacefully” with cancer and improve their quality of life. Allowing cancer patients to “live peacefully” with cancer is a fundamental change in the concept of cancer treatment in modern medicine. Generally speaking, when cancer is in a stable stage, that is, when the tumor in human body stops growing or grows slowly, cancer patients and tumors can “peacefully coexist” and give up the original tactic of “war of annihilation” and fight a “tug-of-war” with cancer mainly to improve their own immunity. The “tug-of-war” with cancer is based on improving the immune system. Scientific research shows that the cancer-fighting ability in human body is huge, and if it is properly mobilized, its anti-cancer power will be tens of times higher than usual. What’s more, the immune balance of the body is regulated from within without any side effects. In this way, we do not have to kill cancer cells at the expense of normal cells, but let them “coexist peacefully” in the body, so that cancer can become a common chronic disease like diabetes and heart disease. For patients with mid- to late-stage cancer, their tolerance to various traumatic therapies is very poor, coupled with the slow growth of their cancer tumors, instead of killing the cancer, they suffer from it and even die faster. In recent years, I have shifted the focus of treatment from simply suppressing and killing cancer tumors to eliminating symptoms, improving quality of life, enhancing functional status, and extending life span, which has achieved obvious results. For patients who have lost the chance of radical treatment, the focus of treatment should be on how to mobilize patients’ own positive factors, inhibit the development of tumor, improve the pain caused by tumor, improve their quality of life, and promote their recovery on this basis. The idea of “Surviving with cancer, dancing with cancer” reveals the true meaning of treatment for middle and late stage malignant tumors from the root. In other words, human life can co-exist with and fight against tumor. The patient’s diet and living are the same as normal people, and the condition is stable and even gradually recovered, forming a situation that tumor and human being “coexist peacefully”. Chinese medicine treatment of tumor includes two aspects, namely local treatment for the cancer itself and overall treatment for the affected host. Local treatment can significantly reduce the tumor load in a short period of time and give the host a chance to recover, thus making it possible to eliminate the cancer eventually. However, local treatment alone cannot prevent the development of residual cancer foci as well as recurrence and metastasis in the future. Chinese medicine has its advantages in this regard. In addition to restoring all aspects of the host’s function, holistic treatment is also quite effective in preventing metastasis and recurrence of cancer. However, the local elimination of cancer tumor is not obvious enough by simple holistic treatment. Therefore, the combination of both local treatment and holistic treatment has the potential to significantly improve the quality of life and survival rate of cancer patients. Chinese medicine emphasizes holistic concept and evidence-based treatment. The characteristics and advantages of TCM in treating cancer and pre-cancerous lesions are mainly focused on three aspects: First, the diversity of treatment methods. Discriminatory treatment, treatment rules and prescriptions are the core elements of TCM tumor treatment, together with qigong, acupuncture and other means, which are more relevant to the clinical characteristics of complex and variable tumors and large differences in individual treatment responses. Secondly, it is rich in clinical experience. After more than 3,000 years, TCM tumor treatment has accumulated clinical experience with great reference value. Thirdly, the clinical efficacy is more accurate. This is mainly from the perspective of macroscopic overall regulation of TCM. TCM treatment for tumor can improve patients’ quality of survival, reduce pain, increase remission rate, prolong survival period, prevent tumor occurrence and delay tumor development, and for some patients there are unanticipated effects such as shrinking tumor mass and eliminating cancer cells. To sum up, the treatment of tumor by TCM is characterized by interrelated and holistic method of discernment and unification, which is unique in adjusting body functions, enhancing resistance, improving symptoms, alleviating pain, controlling tumor development and prolonging life.
