Traditional Chinese medicine is a medical and pharmaceutical system that reflects the Chinese nation's understanding of life, health, and diseases, with a long historical tradition and unique theories and technical methods. It plays an important role in the prevention and treatment of various diseases. During the National Cancer Prevention and Control Week this year, Professor Hou Wei, Director of the Department of Oncology of Guang'anmen Hospital, China Academy of Chinese Medical Sciences, said in an exclusive interview with Xinhuanet that TCM has unique advantages and important significance in the prevention and treatment of tumors at all stages of their occurrence and development. It is important to run through the "whole process" of tumor prevention and treatment, and the sooner the better. The latest national cancer registration data shows that there were approximately 4.06 million new cancer cases reported throughout the year, and cancer remains a major disease that endangers people's lives and health. The causes of cancer formation include various endogenous and exogenous factors, from individual genes to lifestyle to environment, which can all lead to the occurrence of cancer. For example, the environment in which tumors grow is also a key factor in tumor recurrence and metastasis. In recent years, experts at home and abroad have carried out a lot of research around the "tumor microenvironment". "Many cancers are caused by gene mutations. Some have developed effective targets, such as common lung cancer, breast cancer, lymphoma, etc. Targeted drugs have played a very good role; some tumors are caused by gene mutations, but no good therapeutic drugs have been found; others have no gene mutations, and no good therapeutic drugs have been found. Targeted drugs are prone to drug resistance problems, and drug resistance has been found for a year or even months 。” Hou Wei said that tumor intervention is a very complex process. Traditional Chinese and Western medicine are interconnected, both aimed at better helping patients recover their health. The core idea of traditional Chinese medicine in treating diseases is a holistic approach and dialectical treatment, which is not troubled by its molecular level variation and drug resistance. The main focus is to treat people with tumors, not just those on the body. Improving the "soil" environment for tumor growth is fundamental. This is similar to the theory of "seeds and soil", where "seeds" are cells with infinite proliferative ability generated by genetic factors and changes in the internal environment, namely tumor cells; The growth environment it is in is known as the 'soil'. To effectively prevent and treat tumors, it is necessary to remove "seeds" and improve the "soil" environment. Hou Wei stated that the key to treating tumors with traditional Chinese medicine is to "nourish the body and nourish the foundation", which achieves dynamic balance of the internal environment by comprehensively regulating the overall human body. So the traditional Chinese medicine treatment of tumor diseases is also a process of comprehensive treatment throughout the body. Traditional Chinese medicine has different treatment methods for each stage of tumor occurrence and development. In modern medicine, during the treatment of malignant tumors, surgery is performed to remove the focus, and tumor growth is controlled through radiotherapy and chemotherapy. This process has great damage and toxic side effects on human organ and tissues. Traditional Chinese medicine is widely used in tumor treatment, running through the "entire process" of tumor prevention and treatment, from preventing tumor occurrence, reducing the toxic and side effects of radiotherapy and chemotherapy, prolonging survival time, improving late stage patient symptoms, to improving quality of life. Moreover, traditional Chinese medicine is mostly natural drugs, many of which are substances of the same origin as medicine and food, with minimal side effects. These are important advantages of traditional Chinese medicine in preventing and treating tumors. Hou Wei said that in order to benefit more patients from the diagnosis and treatment of traditional Chinese medicine, the hospital's oncology department actively "goes global" and has established cooperative relationships with many national clinical research institutions, such as in 2007
