Why Optune exists
Optune delivers Tumor Treating Fields (TTFields) therapy, a treatment that uses electric fields to disrupt cancer cells, offered as an option for GBM. For patients researching what else can be done, it represents a different kind of mechanism: attacking tumor cells with fields rather than with drugs alone, within the electric fields and thermotherapy category.
