A ‘sci-fi’ therapy to fight brain tumours (Relevant for GS Prelims and GS Mains Paper III)

Optune, a cap-like device that creates electric fields, improves survival
It sounds like science fiction, but a cap-like device that makes electric fields to fight cancer improved survival for people with deadly brain tumors. Patients cover their shaved scalp with strips of electrodes connected by wires to a small generator 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 is not an electric current or radiation, and they feel only mild heat

About the Optune
The Optune is used for adults with brain tumours and is used with chemo after surgery and radiation to try to keep these tumours from recurring.

How does it work?
It supposedly works by creating low-intensity, alternating electric fields that disrupt cell division.
