Blue Light Tool Can Detect Oral Cancer Cells

Canadian researchers have reported that a device that emits blue light can help to save the lives of patients suffering from oral cancer.

The handheld fluorescence visualisation tool allows surgeons to see cancer cells that can't be detected by conventional white light, helping doctors to only remove tissue that is cancerous.

Miriam Rosin, lead investigator of a study of the tool, developed at the BC Cancer Agency, said that this was the first time that it has been used surgically for oral cancer.

The device has already been used to detect lung, cervical and skin cancers.
