Tumor Treating Fields (TTF) : New Breakthrough Technology to Treat Cancer

We know that Surgery, Chemotherapy and Radiation are the best-known methods for treating cancer. A new fourth tool called Tumor Treating Fields, uses electric fields to interrupt cancer cell division. Here is a great talk by Bill Doyle from Novocure at TEDMED …


  • Tumor Treating Fields uses externally placed transducer array attached to a field generator and create and artificial electric field in the cells.
  • It slows and reverses tumor cell proliferation by inhibiting mitosis, the process by which cells divide and replicate themselves.
  • TTF creates a low-intensity, alternating electric field within the tumor that exerts physical forces on electrically charged cellular components, preventing the normal mitotic process and causing cancer cell death prior to division.
