Tumors are a genetic disorder, but are not inherited. It is a new organism formed by that the cell gene is changed under the action of carcinogenic factor, and loses the normal regulation and control of its growth, so that it can result in the abnormal proliferation of monoclonality. This neoplasm often forms localized lumps and is thus named. According to the biological characteristics of tumors and the difference of harmfulness to organisms, tumors can be divided into two major types, namely benign tumors and malignant tumors. The former has slow growth, clear boundary with surrounding tissues, no transfer and little harm to human health. The latter grows rapidly, can be transferred to other parts of the body, can also produce harmful substances, damage normal organ structures, cause organism dysfunction and threaten life. There is a fundamental distinction between neoplastic and non-neoplastic hyperplasia: the non-tumor hyperplasia is required for the living of the organism, the hyperplastic tissue can be differentiated and matured, and the structure and the function of the original normal tissue can be recovered, and the hyperplasia can not be continued to a certain extent. The normal cells are transformed into tumor cells, have abnormal shapes, metabolism and functions, lose the capacity of differentiation and maturation to different degrees, grow vigorously and have relative autonomy, and can grow continuously even if no tumorigenic factors exist later.
