Scientists at Warwick University devise new way to detect skin cancer

Scientists at the University of Warwick have created a new way to detect skin cancer, using so called Terahertz (THz) waves, the BBC said in a new report published on its website.

According to specialists, THz waves fall between infrared (used in remote controls) and microwaves on the electromagnetic spectrum. They can be used in scans to map the extent of tumours more accurately.

“In skin cancers, the amount of water in the skin is different when compared to the healthy skin around it,” said Prof Emma MacPherson, adding that “In theory you could use a THz wave producing machine to map very accurately the extent of any skin cancer.”
