Radioactive Drugs Strike Cancer with Precision

June 17, 2024

(Knowable Magazine) – Radiation therapy has come a long way since those early beginnings. The discovery of radium and other radioactive metals opened the doors to administering higher doses of radiation to target cancers located deeper within the body. The introduction of proton therapy later made it possible to precisely guide radiation beams to tumors, thus reducing damage to surrounding healthy tissues — a degree of accuracy that was further refined through improvements in medical physics, computer technologies and state-of-the-art imaging techniques.

But it wasn’t until the new millennium, with the arrival of targeted radiopharmaceuticals, that the field achieved a new level of molecular precision. These agents, akin to heat-seeking missiles programmed to hunt down cancer, journey through the bloodstream to deliver their radioactive warheads directly at the tumor site. (Read More)
