Combining with the results of modern research

this paper explored the effects of repeated exogenous pathogen on the course of disease for cancer patients

and demonstrated the correlation between exogenous pathogen and occurrence and development of tumors. It is suggested that the pathogenesis of exogenous pathogens to promote tumor metastasis is external pathogens entering inside and accumulation of stasis and toxin; external wind fleeing hither and thither

causing movement of internal pathogen. For treatment

dispelling and promoting can be applied to dispel the pathogens and the wind medicinals should be properly used.
