Doctors will today unveil the world's first sticking plaster that can cure cancer.
The high-tech device contains a small light that combines with a chemical cream to kill skin cancer cells.
The Ambulight plaster has already been used on 50 patients with a success rate of up to 90 percent. It is less painful than surgery and leaves no scar.
Muriel Lowe, who had two treatments a week apart, described the result as "fantastic."
"I have a skin condition that means normal surgery would scar me," she said.
"The doctor told me that cosmetically this would be much better. The treatment is called photodynamic therapy."
A cream containing a harmless chemical is rubbed into the skin where it is absorbed by skin cancer cells, but not healthy tissue.
