In Chinese medicine, the basis for the progressive development of carcinoma can be explained in modern terms as the imbalance of the internal environment and microenvironment, which can be summarized as the imbalance of yin and yang from the perspective of Chinese medicine. 1. qi-depressed state: abnormal operation of qi, stagnation or rebellion is the most basic pathological state that leads to the development of carcinoma. 2. In the early stage of cancer, there is a long period of stagnation of qi. 2. Qi deficiency: According to Chinese medicine, weakness of qi and blood will lead to all kinds of diseases, especially the deficiency of qi, which is often one of the main pathological bases of cancer. 3. Dampness obstruction: Dampness is wetness, and qi deficiency and qi depression often lead to abnormal metabolism of fluid in the body, resulting in dampness stagnation and dampness obstruction. In ancient times, it is said that “dampness and turbidity produce all kinds of diseases”, and clinical practice also shows that the effect of tumor treatment and prevention of metastasis and recurrence can be significantly improved by using dampness and phlegm-transforming drugs. 4. The existence of cancer tumor and the treatment measures such as chemotherapy and radiotherapy for cancer tumor will aggravate the blood stasis, thus forming a vicious cycle of knot. These are the main causes of tumors according to Chinese medicine.
