In September 2008, Master Wu, who lives in Jiangning District, was diagnosed with stomach cancer. After surgery, he underwent chemotherapy, during which he could not bear the pain of chemotherapy, and started to try Chinese medicine treatment in the interval, which greatly reduced the toxic side effects of chemotherapy, such as vomiting and nausea. After the experts rationally selected Chinese medicine according to his condition, he had a comprehensive checkup once every 3 months on average. So far, his condition is very stable and all the examination indicators are normal. At present, the advantages of Chinese medicine in assisting cancer treatment mainly include the following six points: First, it has a strong overall concept. Although tumors grow locally in the body, they are actually local manifestations of a systemic disease. Chinese medicine starts from the overall concept and implements evidence-based treatment, which plays an important role in improving both the local discomfort symptoms and the general condition of patients. Secondly, it can make up for the insufficiency of surgical treatment, radiotherapy and chemotherapy. The use of TCM for postoperative treatment of tumor and cancer can prevent recurrence and metastasis. Thirdly, TCM treatment can not only smoothly help patients to complete the course of radiotherapy and chemotherapy, but also significantly reduce the toxicity and increase the effect. Fourthly, it does not affect the labor force. While the local condition of cancer patients improves, their general condition also improves, and they are even able to perform their daily work. Fifth, the side effects are small. There is no side effect of myelosuppression, and there is no serious effect on the digestive tract. Sixthly, it is economically cheaper, which is affordable to the majority of patients and convenient to take. In addition, in the Chinese medicine treatment of malignant tumors of various treatment rules, “poison to fight poison” method has been valued by successive generations of doctors, this point should be rationally viewed by patients. The method of “attacking poison with poison” aims at eliminating evils and attacking cancer, thus it is adapted to cancer patients with “accumulation of firmness and solidity of qi”. Commonly used medicines include animal drugs: toadstools, speckled fibers, snake venom, shougong, scorpions, centipedes, soft-shelled turtle worms, leeches, etc.; plant drugs: raw half-summer, raw southern star, Crow’s gall, Croton, Garcinia Cambogia, etc.; Minerals: Arsenic, Arsenic, Andrographis, Light powder, etc. While killing tumor cells, these medicines also have certain damage to normal cells, so in the case that the positive qi has not been exhausted and can be attacked again, the toxicity can be borrowed to fight against cancer. However, if the positive qi of the tumor patient has been damaged, its treatment cannot be fierce attack, and attention must be paid to carefully grasp the dose and stop. It is common for some patients to blindly believe in the so-called secret formula composed of a large number of toxic drugs and take them for a long time without the guidance of physicians. This is not only not conducive to the treatment of primary tumor, but also may cause serious damage to the patient’s body. Therefore, Chinese medicine treatment for tumor patients should be adjusted according to the existing treatment plan under the guidance of regular doctors, and should never listen to some anti-cancer prescriptions, lest it will bring unimaginable consequences.
