Abstract: Use of phosphorus-based material in preparation of medicament for treating tumors. The phosphorus-based material is selected from a material which is convertible to produce phosphate ions in an acidic environment, and the phosphorus-based material can be converted by tumor cells phagocytosis to produce a large number of phosphate ions to change the intraceullar environment and extracellular environment, thereby inhibiting proliferation of tumor cells and inducing death of tumor cells. This process has no significant effect on normal cell activities. By applying the phosphorus-based material to the preparation of a medicament for treating tumor in a manner as mentioned above, the amplification and metastasis of tumor cells can be effectively inhibited, thereby the metastasis of the tumor cells and recurrence of the tumor can be prevented more effectively, improving the therapeutic effect of the tumor. The phosphorus-based material has little effect on normal cells and tissues in the course of treatment.
