Selfies for melanoma detection
A US based study using self photographes and Apple software is trying to see if this can be used to detect melanoma early. A paper in the British Journal of Dermatology by Peter Soyer et al showed that selfies of patient- identified suspicious moles with a cheap smartphone dermoscope was feasible.
In the end though, what really matters is people looking out for new and funny moles and easy access to a trained, capable dermoscopist. I am currently working on a presentation about mole monitoring and will post a summary here. Based on what I have been able to learn, there is a lot to be said for selfie mole mapping and 3 monthly review by a friend or relative, with easy access to an expert opinion in the event of a new or changing mole.
