Smartphone apps claiming to diagnose deadly melanoma cancers wrongly dismissed almost one in three suspicious moles, warn researchers.
The inaccurate feedback could result in life-threatening delays in visiting the doctor and getting treatment, they say.
A new study found three out of four apps set up to check a user’s photos of skin lesions was giving misleading results.
They diagnosed 30 per cent or more melanomas as ‘unconcerning’, when they are the deadliest of skin cancers.
The study comes amid the growing popularity of smartphone apps designed to give health advice.
Malignant melanoma is the most serious type of skin cancer, with more than 11,700 Britons diagnosed each year and 2,300 people dying.
