This book tries to answer what, how, and why of the malignant mass questions from the perspectives of the Chinese herbal remedies. This book has collected as much as possible all information relate to malignant mass, such as symptoms, signs, and carcinogenic risk factors. There are analyses of information to find out main pathogens, location and storage, main pathogenesis and location (initiate attack), characteristics and definition of malignant mass. This book considers that the all kinds of malignant mass are caused by a few main pathogens. The main pathogens' property are excess dry heat, malignant dry heat, and malignant mass dry heat. The main pathogens' materials are the excess dry heat particles, malignant dry heat particles, and malignant mass dry heat particles. The body has several production bases for all levels of dry heat pathogens. The malignant dry heat has two ways or two types which form the malignant mass - one is gradually and chronically, another one is acute and suddenly. The Chinese herbal remedies and formulas cannot directly deal with the malignant dry heat and malignant mass dry heat. But, Chinese herbal remedies and formulas are able to deal with the excess dry heat. The excess dry heat is the foundation of the malignant dry heat and malignant mass dry heat. When the excess dry heat is in the deficiency condition, the malignant dry heat will transfer power to support the excess dry heat, and the malignant dry heat will be in the deficiency condition. When the malignant dry heat is in the deficiency condition, the malignant mass dry heat will transfer power to support the malignant dry heat; the malignant mass dry heat will be in the deficiency condition. When the malignant mass dry heat is in the deficiency condition, the solid malignant mass will transfer power to support malignant mass dry heat; the malignant mass will be in the deficiency condition. When the malignant mass is in the deficiency condition, the malignant mass will lose power and materials; that means mass size will be reduced and shrunk. The Chinese herbal remedies and formulas can reduce the excess dry heat to deal with the malignant mass. The malignant mass is not created in one day. It is a chronic condition with acute flare up situation. In order to deal with the malignant mass, one must deal with the quantity of the excess dry heat in order to change the quality of the malignant dry heat.
