In the initial stage of growth of tumor cells,tumor cell growth was exponential model.Because the lack of nutrient supply,peripheral vascular and other factors,tumor cells was deviated the exponential model in the late stage of growth.In this paper,we analysis the growth conditions of tumor cells in the two aspects which are the population and the vohume of tumor cells,and give ascending descending interval and the extreme point of the populations of tumor cells.The results of the analysis is consistent with the observations,and provide a strong theoretical basis for the clinical diagnosis of cancer patients.
