Laser test that spots skin cancer with­out a biopsy

Daily Mail - - Good Health -

A NEW 60-sec­ond scan can de­tect skin cancer with­out a biopsy.

The de­vice checks for basal cell car­ci­noma (BCC), a com­mon type of skin cancer that ac­counts for 75 per cent of cases.

Cur­rently, der­ma­tol­o­gists ex­am­ine the skin by eye and per­form a nee­dle biopsy if nec­es­sary. The VivoSight scan­ner, re­cently ap­proved for use in Bri­tain, is held against the skin for less than a minute. It fires out beams of laser light and, based on how these bounce back, cre­ates an im­age.

A der­ma­tol­o­gist then ex­am­ines this for tell-tale signs of cancer. The scan­ner was able to di­ag­nose BCC in 48 per cent more cases than by eye, says re­search by the man­u­fac­tur­ers pub­lished in the Jour­nal of Clin­i­cal and Aes­thetic Der­ma­tol­ogy.
