There was a time when cancer took away many splendid lives and people talked about it with fear. Is cancer really an incurable disease, is there really no cure, does it really mean death? In fact, cancer is not as hideous as imagined. After correctly understanding the known causes and treatments of cancer, cancer patients and their family members will surely build up their confidence in fighting cancer. The understanding of cancer in Chinese medicine and Western medicine] Chinese medicine considers that cancer is caused by external factors (six perversions) and internal factors (injury caused by emotion, diet, labor, etc.), resulting in the accumulation of pathological products such as qi stagnation, blood stasis, phlegm-dampness cohesion, poisonous heat, etc., which become cancerous tumors, and is a local reaction to the systemic disease. According to generations of medical practitioners, the most critical factor for the occurrence of tumor is that the body’s positive energy is not sufficient to resist the invasion of the six external influences. As the saying goes, “Where the evil comes together, its qi will be deficient” and “If the positive qi is deficient, it will become cancer”; secondly, the strength of the human body has a great relationship with the occurrence of tumor. As pointed out in the Emperor’s Classic of Internal Medicine, the human body is endowed with strength and flexibility, physical strength and weakness, and yin and yang attributes; in addition, the role of other acquired factors, such as dietary habits, mental and emotional states, and natural environmental influences, can directly or indirectly lead to the occurrence of cancer. Modern medical science believes that carcinogenesis is caused by carcinogenic substances that change the genetic information of cells and the structure of DNA in the nucleus, which activates the original oncogene and inactivates the oncogene, prompting normal cells to differentiate or transform into cancer cells. Cancer may be due to abnormal genetic performance, but it does not necessarily require structural changes of genes, thus cancer is possible to recover. The most distinctive feature of TCM is that it starts from a holistic approach, which is characterized by the “holistic concept” and “diagnosis and treatment”. The understanding of diseases in TCM mainly comes from the thorough observation of nature, social environment and the external reactions of human body, i.e., through looking, smelling, asking and cutting, and the comprehensive analysis of the collected data, in order to infer the changes of yin and yang of the body (internal pathology), predict the cold, heat and deficiency of the disease, so as to make a judgment on the symptoms of the disease. TCM requires comprehensive treatment of cancer under the guidance of TCM theory, discriminatory treatment, organic combination with modern medical technology, planned and rational application of various existing therapeutic means, maximizing the advantages of TCM holistic treatment, striving for the whole treatment of TCM in tumor, restoring the dynamic balance of the organism, with a view to improving the sensitivity of radiotherapy and chemotherapy, minimizing toxic side effects, anti-tumor metastasis and recurrence It aims to improve the quality of life of advanced cancer patients and prolong the survival period with tumor. Western medicine is a science of human body based on the development of modern natural science, which is mainly manifested in the anatomical understanding of human tissue structure, the study of pathophysiological changes in human tissues, the examination of etiology and pathogenesis in clinical practice, the objective manifestation of diseases and the pathological damage related to local tissues and organs, and the use of modern biology, physics, chemistry and other disciplines with various advanced technical means in the diagnosis and treatment of diseases. The Department of Medicine emphasizes the accurate characterization and localization of the disease, and the localization and treatment of the disease. We emphasize the accurate qualitative positioning of the disease, the consistency between local and overall, structure and function, connotation and extension, and the quantification of the relevant indicators of the disease as far as possible. In the treatment of cancer, emphasis is placed on minimizing the tumor load. The treatment mode of TCM and Western medicine for cancer treatment] Modern TCM has broken through the traditional framework and added the integrated treatment mode of combining Chinese and Western medicine on top of the classical treatment mode of identifying disease plus evidence. The combination of disease identification and evidence-based TCM treatment often refers to the addition of some anti-cancer herbs to the formula to enhance the efficacy based on the evidence-based treatment. Integrated treatment of Chinese and Western medicine means that surgery, radiotherapy and chemotherapy are applied simultaneously or successively. The application of Chinese herbal medicine at the same time or successively with chemotherapy can achieve the multi-win effect of improving the therapeutic effect, reducing the toxic side effects of treatment, improving the quality of survival and increasing the survival rate. The treatment mode of modern medicine is still mainly based on surgery, which is generally applicable to cases where the cancer is still limited to the primary site and regional lymph nodes in the early stage; radiotherapy is applicable to cases where the cancer is sensitive to radiation in the early and middle stages (such as nasopharyngeal cancer, vocal cord cancer, skin cancer, tongue cancer, breast cancer, spermatocellular carcinoma, Hodgkin’s disease, etc.) and the lesions are limited; chemotherapy is mainly used for the treatment of patients in the late stage, the adjuvant therapy of surgery or radiotherapy, and the adjuvant therapy of chemotherapy. Biological therapies are based on immunotherapy and are mainly used to improve the host’s immune response to cancer; to modify cancer to induce strong response; to promote differentiation, maturation and normalization of cancer cells; to reduce the adverse effects of radiotherapy and enhance the host’s tolerance; etc. Although both TCM and Western medicine have their own uniqueness in cancer treatment, the disadvantages of both sides are also obvious. Chinese medicine has insufficient understanding of disease microscopy, and some treatment methods cannot be found on scientific basis; while Western medicine overemphasizes the qualitative positioning of disease and ignores the overall response and dynamic changes of the body during the disease process. Therefore, the combination of Chinese and Western medicine has gradually surfaced and shown its superiority, forming a new clinical thinking based on “combination of disease identification and evidence identification”, “combination of macroscopic evidence identification and microscopic evidence identification” and human-oriented. In the process of clinical diagnosis and treatment of cancer, the combination of Chinese and Western medicine considers the human body and cancer changes as a whole, makes full use of various advanced technologies and methods of modern science, gives full play to the respective advantages of Chinese and Western medicine, and combines some microscopic indicators of modern research results on “evidence” to make a corresponding new diagnosis of evidence; combines local pathological changes and the overall response and dynamics of the human body in the process of disease. We combine the local pathological changes with the overall response and dynamic changes of the human body in the disease process. When the cancer needs to be eradicated and can be eradicated, we do not hesitate to eliminate it in a big way. When the cancer is tumor-free or the disease is stable, we will use Chinese and Western medicine to support the treatment, and/or supplement with intermittent anti-cancer treatment for a certain period of time until the recurrence rate of the cancer is reduced to a minimum. The feasibility and significance of “survival with tumor”] At present, it is believed that cancer is a local manifestation of systemic disease. Therefore, even if the tumor, which is the biggest superfluous organism in human body, is removed and the damage caused by tumor cells to the body is controlled, it does not mean that the disease is cured. However, this does not mean that tumor patients are deprived of the right to live. In fact, in clinical tumor regression, “survival with tumor” is common. In other words, sometimes the cancer cannot be completely eliminated, but it can coexist, which we often explain to patients in clinical practice as “living with tumor”. At this time, patients can imagine the tumor cells as a resilient enemy, a series of treatment has hit the enemy hard but still cannot destroy them in one go, what we can do is to trap them in their own bunker and cut off their food, always monitor their actions and stop them from growing. At the same time, the patient should constantly pay attention to improve their own resistance to the enemy, that is, their own immunity, when the enemy runs out of ammunition, the party will be wiped out. Of course, this process is long, some patients may live with tumor for the rest of their lives, but they can still enjoy their lives as healthy people as long as they have regular review and adhere to the “corrective” treatment. Chinese medicine has a tradition of “helping the righteous to remove the great accumulation”. We have many successful cases of patients who, for various reasons, did not have surgery or could not have surgery, and even cancer patients whose tumors could not be removed after the surgeon’s dissection. Many of them survived for a long time after their long-term supportive treatment by TCM. There was a pancreatic cancer patient whose tumor could not be resected after dissection and was pathologically diagnosed as hypofractionated adenocarcinoma. After a short period of low-dose chemotherapy and long-term Chinese herbal remedial treatment, he has been surviving with the tumor for 8 years until now. Therefore, it is possible to look at cancer as a chronic disease and reconceptualize the meaning of survival with tumor.
