Electric fields device by Novocure shows promise in extending lung cancer survival.

Novocure's medical device, Optune, which creates electric fields in the lungs via wearable skin patches, extended the survival of patients with lung cancer in a clinical trial. The study achieved its primary goal and showed a survival benefit for patients with lung cancer that progressed following initial chemotherapy. However, doubts remain as the data doesn't fit the current medical practice for patients with lung cancer.
