Doctors have unveiled the world’s first adhesive band-aid that can cure cancer. The high-tech device contains a small light that combines with a chemical cream to kill skin cancer cells. A cream containing a harmless chemical is rubbed into the skin where it is absorbed by skin cancer cells, but not healthy tissue. Three hours later the LED in the band-aid automatically switches on a for pre-programmed duration, converting the chemical into a lethal drug. It kills the cancer, but minimizes collateral damage to healthy cells. The Ambulight band-aid has already been used on 50 patients with a success rate of up to 90%. It is less painful than surgery and leaves no scar.
