Non-invasive wearable device: A cap-like device that makes electric fields fight cancer has improved survival for the first time in more than a decade for people with deadly brain tumours, the final results of a large study suggest. The device, called Optune, is made by Novocure, based in Jersey and is sold in the U.S., Germany, Switzerland and Japan for adults with an aggressive cancer called glioblastoma multiforme. Patients cover their shaved scalp with strips of electrodes connected by wires to a small generator kept in a bag. They can wear a hat, go about their usual lives, and are supposed to use the device at least 18 hours a day. It supposedly works by creating low intensity, alternating electric fields that disrupt cell division, which makes the cells die. Picture shows Joyce Endresen wearing the device while at work in Aurora, Illinois, U.S., in March this year. She was diagnosed in December 2014 with glioblastoma. AP
