On Tumor Differentiation and Treatment by TCM

Tumor differentiation and treatment by TCM is discussed in this paper and the academic thought of "cancerous toxin" has been raised based on the clinical practice of determining etiologic factors based on differentiation and treating tumor by ways of dispelling poison， detoxifying and counteracting toxic substances. Tumor is considered to be the result of the disorder of qi transformation of zang-fu organs， with phlegm and toxicity stasis as the core of the pathogenesis. Thus， syndrome and disease differentiation should be complementary and the development of evil qi and vital qi， the connection between tumor and the diseases should be fully considered.

For example， relieving symptoms are of great importance and the recurrence and metastasis of tumor should be stopped and the most important thing is to nourish the vital qi.
