The transfer of tumor (tumor metastasis) is composed of a series of discrete biological processes, making tumor cells from the primary tumor to the remote parts of the process. Tumor cells invade surrounding tissue, tumor (invade) primary enters lymphatic fluid or blood, in the circulatory system, can survive and remain in it, then spilled from the vascular (extravasate) to form a solid tumor proliferation in new places. This process mainly involves the interaction of tumor cells and their surrounding environment and the regulation of many kinds of factors. This paper simply introduces the occurrence, development and classification of the tumor metastasis and some factors include body tyrosine kinase Abl (Abelson kinase) on the impact of the process
