Novocure was founded to provide patients with a new cancer treatment based on using alternating electric fields, when applied at specific frequencies, can disrupt cancer cell division and cause cancer cell death. This innovative treatment, Tumor Treating Fields, is a completely different approach to cancer therapy. What are TTFields?TTFields are electric fields that exert physical forces to kill cancer cells via a variety of mechanisms.Electric fields have different effects on the human body depending on their frequency, leading to diverse applications in healthcare such as microwave ablation, deep brain stimulation, and pacemakers.
