Doctors cured cancer in mice with a radioactive gel.

Indian and American scientists created a protein gel with atoms of radioactive iodine-131 and with its help they cured pancreatic cancer in laboratory rodents - the tumors disappeared in 80% of the animals. The new method combines elements of chemotherapy and radiotherapy, but is not so dangerous for healthy tissues. The gel was injected directly into the tumor. It was destroyed by beta radiation that arose after the decay of the nuclei of unstable iodine-131. Beta radiation does not penetrate as deeply as gamma rays, so doctors managed to achieve a point effect. Due to the special structure of the protein part of the gel, it was easily excreted from the body after the procedure.
