Both Bayer and Merck have been working on destroying tumors without damaging the surrounding tissue for decades. Bayer even bought a company to help and they still can't do it without damaging the surrounding tissue. The are shooting for an acceptable amount of damage! What acceptable damage? Maybe they should buy RDGL. Here is your proof:
explains Dr. Alan Cuthbertson, Head of Thorium Research at Bayer in Oslo, Norway. He and his team were part of Algeta ASA, a company that was acquired by Bayer in 2013. These specialists in the use of alpha particle-emittting radionuclides in radiotherapy are working on a means of transporting thorium directly to the tumor where the radioisotope first accumulates and then decays, releasing the alpha particles. “The radiation then destroys cancer cells without damaging the surrounding healthy tissue too severely,” explains the Bayer chemist.
