Treatment using tumour therapy fields is based on the observation that rapidly changing electric fields disturb the cell division of brain tumours. It is an established, non-invasive procedure for the treatment of patients with glioblastoma.
In this method, several electrodes are applied to the scalp and connected to a therapy device. The system must then be worn as permanently as possible. As a rule, this therapy is used in addition to the standardised combined radiation chemotherapy. It can also be used in the event of tumour recurrence.
