As you probably know, I live in Arizona, where you can get a sunburn just about any time of the year. You don't even have to be outside very long.
Sunscreen is a must, as too much sun exposure can lead to skin cancer, especially the dangerous melanoma. Without early detection and treatment, melanoma can be deadly.
That's why the a new screening system could save a lot of lives. It's the brainchild of George Zouridakis who is a professor of engineering technology at the University of Houston.
The screening system consists of a magnifying lens and special light - called a dermoscope - that slides over an iPhone camera, and the DermoScreen app. You simply take a picture of a suspicious mole or skin spot and the app can tell if it's cancer or not in a few seconds.
So far testing at the University of Texas MD Anderson Cancer Center shows that the apps is accurate 85 percent of the time. This is a better detection rate than most primary care physicians and nearly on par with dermatologists.
The hardware does cost $500, plus you need an iPhone. However, it could be invaluable for screenings in rural and undeveloped areas without access to a qualified doctor.
This isn't the first time smartphones are being used for medical purposes. Here are a bunch of apps that can help you diagnose illness, find a doctor, refill prescriptions and much more.
