Brain Tumor 'Helmet'

Battery-powered helmet may benefit patients with brain tumors.
Bloomberg News (6/5, Randall) reported that a "helmet, powered by a six-pound battery pack," may benefit patients with brain tumors, according to a study presented at the annual meeting of the American Society of Clinical Oncology. Researchers found that the helmet "helped patients with recurrent tumors live 7.8 months, compared with a median 6.1 months for patients given the best available chemotherapies or Roche AG's Avastin." Bloomberg added that "the electric fields resonate at a frequency designed to do no harm to healthy brain tissue."
