Drinking Chinese medicine for a long period of time does not curb cancer recurrence, and usually does not lead to cancer recurrence. Cancer is malignant tumor, and cancer recurrence refers to the reappearance of malignant tumor locally, or the metastasis of lymph nodes or organs. The cause of cancer recurrence is due to the fact that the tumor cells have not been completely killed, and the treatments for recurrence are mainly based on chemotherapy, radiotherapy, surgery, targeted therapy, immunotherapy and so on. There is no evidence-based medical evidence for Chinese medicine to control cancer, and it is mostly used as an adjuvant therapy to regulate the recovery after anti-tumor treatment, and cannot solely rely on Chinese medicine to control tumor recurrence. The composition of Chinese medicines is complicated, the dosage is not exact, and the pharmacology and toxicology of many medicines have not yet been demonstrated by clinical medical tests. If Chinese medicines are taken for a long period of time, they may cause damages to the liver and kidney functions. However, in general, if long-term use of Chinese medicine is needed for the treatment of the disease, then long-term consumption of Chinese medicine is a process of treatment and conditioning of the body, so that the body of the cancer patient can be restored, and usually long-term consumption of Chinese medicine in this case will not lead to the recurrence of cancer. If there is any discomfort, it is necessary to use the medicine under the guidance of specialized doctors, and not to blindly use the medicine by oneself, so as not to cause adverse effects on the body.
