Many tumor patients have to take traditional Chinese medicine for conditioning after surgery or before and after radiotherapy or chemotherapy. So what does traditional Chinese medicine do to the prognosis of tumor patients, is it like many patients have to take traditional Chinese medicine for one or two years? Tumors should be detected and treated early, and it is best to implement individualized treatment with Chinese and Western medicine. Chinese medicine emphasizes on “survival with tumor”. Chinese medicine focuses on adjusting the internal environment of tumor patients, increasing immunity, improving tolerance to surgery and radiotherapy, and reducing the toxic side effects of radiotherapy. For some patients who cannot receive radiotherapy or chemotherapy, it is more appropriate and beneficial to take traditional Chinese medicine treatment, such as old and weak liver patients, many of whom cannot stand the stimulation of radiotherapy and chemotherapy and are more willing to receive traditional Chinese medicine treatment. Especially for some older patients, the growth rate of tumor is relatively slow, and the effect of adjustment with Chinese medicine treatment is obvious than younger patients. Nowadays, many tumor patients are afraid of cancer metastasis and tend to be over-treated for insurance purposes, such as early stage breast cancer patients, where breast-conserving treatment is entirely possible. Chinese medicine treatment for tumors emphasizes on helping the righteous and eliminating the evil, and improving the quality of survival. Since Chinese medicine mainly adjusts the body function, the effect is relatively slow, while tumor is a systemic disease and is prone to metastasis or recurrence, so it needs to be taken for a long time. Some people only think that ginseng and ganoderma lucidum are good for tumor, but in fact, the effective Chinese medicines for tumor are not only tonic medicines such as astragalus, huai shan, wolfberry, cordyceps and bone marrow, but also those that activate blood stasis, clear heat and detoxify, resolve phlegm and disperse nodules. The key to the effectiveness of the treatment here lies in the rational grouping of prescriptions and the identification and treatment of evidence. Generally speaking, the course of taking Chinese medicine should be at least half a year, and it should be reviewed regularly at the hospital until the patient’s examination results are free of residual tumor and no clinical symptoms, then the dosage can be gradually reduced or even discontinued. Traditional Chinese medicine does not advocate strict taboo. Traditional Chinese medicine believes that tumor patients are more careful in their diet, and Prof. Wang Huijie advocates evidence-based food administration and does not advocate too strict taboo. For elderly patients, who are weak and have insufficient nutrition, it is not necessary to be too strict in avoiding food and it is appropriate to let nature take its course. The recurrence of tumor is not entirely caused by dietary reasons. Of course, some “hairy things” have a certain role in promoting the growth of tumor, such as roasted goose, dog meat, pond lice, eel, etc. It is better not to eat them. For example, in the north, it is not recommended for tumor patients to eat chicken, but Cantonese people especially like to eat chicken, and Chinese doctors think they can eat farm chicken. If the patient’s mouth is dry after radiotherapy, he should not eat dry and fried products, but light and moist products. Patients with poor gastrointestinal function should not eat food that is too cold. In terms of principle, it is necessary to choose foods that are good for health according to each person’s specific situation. In conclusion, tumor is a kind of consuming disease, and patients with good nutrition can survive longer than those with poor nutrition.
