Alternating electric field therapy, sometimes called tumor treating fields, or TTFields, is a type of electromagnetic field therapy using low-intensity electrical fields to treat cancer.
A TTF-generating device called Optune is manufactured by the company, Novocure. Optune is approved in the United States and Europe for the treatment of newly diagnosed and recurrent glioblastoma multiforme, or GBM, and is undergoing clinical trials for several other tumor types.
What is Optune?
Optune is a wearable and portable, FDA-approved device that has been shown in clinical trials to safely deliver continuous therapy to the area of your brain where your GBM tumor is located.
Optune delivers therapy through 4 adhesive patches, called transducer arrays. These transducer arrays are applied to your scalp and are connected to the device and battery.
