The present invention relates to a radioactive or non-radioactive chitosan-chelate hydrogel and a preparing method therefor, and a composition for cancer treatment and embolotherapy containing the same as an active ingredient. The chitosan-chelate hydrogel prepared in a size of 100-300 ㎛ according to the present invention can be used for embolotherapy for cancer tissues by shutting off the blood flow toward tumor tissues to block the supply of oxygen and nutrients to the tumor tissues, and especially, the radionuclide-labeled chitosan-chelate hydrogel, through direct labeling of a radionuclide or immersion in a drug at the time of forming a hydrogel, has excellent labeling efficiency and labeling stability of the radionuclide, thereby minimizing free radionuclides, and is expected to have both a therapeutic effect by the nucleotide and a therapeutic effect by the drug, thereby improving the therapeutic effect of lesions.
