Standard treatment is 6 weeks of high-dose radiation along with a chemotherapy pill, and then additional chemotherapy until the tumor stops responding. With this new system, made by Novocure, 4 electrodes are placed on the surface of the patient’s shaved scalp to deliver low-intensity, electrical fields called tumor treatment fields (TTFs) to the tumor site. Tumor cells that are dividing and multiplying have unique shapes and electrical characteristics. These make them susceptible to damage when exposed to TTF, which then stops the tumor’s growth.
