As a particularly aggressive brain tumor, it almost goes without saying that glioblastomas are scary things.
Called the Optune, it s a wearable device that uses electrodes to send an AC electric field through the brain to attack tumor cells.
Depending on the patient, the technology slows the growth of tumors, stops them growing further, or even shrinks them.
Optune generates what are called tumor-treating fields, Dr. Eilon Kirson, manufacturer Novocure s chief science officer, told Digital Trends.
These are electric fields at an intermediate frequency range, which can be applied to the human body without interfering with neural activity or cardiac activity, and which don t generate any significant heat.
It s at a frequency where the fields penetrate the body, enter cancer cells, and then interfere with the highly choreographed process of the rapid cell division of these cells.
