Electrical Field Treats Brain Cancer

A device that specifically targets rapidly growing cancer cells with intermediate frequency electrical fields doubled the survival rates of patients with brain cancer, according to an article apperaring in PNAS. The device uses electrical fields to disrupt tumour growth by interfering with cell division of cancerous cells, causing them to stop proliferating and die off instead of dividing and growing. Healthy brain cells rarely divide and have different electrical properties than cancerous brain cells. This allows the device to target cancer cells without affecting the healthy cells. Essentially no device-related side effects were seen in the clinical trial — via Slashdot
