Researchers have developed a non-invasive technique that allows clinicians to accurately detect various forms of skin cancer.

The current clinical "gold standard" non-invasive technique, called dermoscopy, is a highly subjective method. But by using what's called Raman spectroscopy, investigators found that could be detected with an accuracy of 91% and non-melanoma skin cancers could be detected with accuracy between 73% and 85%.

"The non-invasive and label-free nature of Raman spectroscopy enables the application in various medical fields. The method could be applied through an endoscope in order to reach internal organs. Besides the detection of , applications to detect cancer of the urinary bladder, esophagus or cervix have been shown," said Dr. Johannes Schleusener, co-author of the Experimental Dermatology article.
