Google AI tool can help patients identify skin conditions

Google has unveiled a tool that uses artificial intelligence to help spot skin, hair and nail conditions, based on images uploaded by patients.

A trial of the "dermatology assist tool", unveiled at the tech giant's annual developer conference, Google IO, should launch later this year, it said.

The app has been awarded a CE mark for use as a medical tool in Europe.

A cancer expert said AI advances could enable doctors to provide more tailored treatment to patients.
