You can already use your smartphone to do things like hail a pimp ride home or order an artisan pizza, obviously the next step is cancer detection, right? Researchers at the University of Houston think they've created a smartphone app that can detect melanoma even better than your doctor. Called DermoScan, the app works by taking a photo of your odd-shaped mole, and then analyzing it to determine if it might be cancerous. Initial testing found that DermoScan was able to identify skin cancer roughly 85 percent of the time, making it just as effective as visiting a dermatologist and even better at diagnosing melanoma than the average primary care physician. Don't head over to the app store just yet. The app requires a special $500 magnifying glass to make the magic happen -- not exactly more cost effective than a trip to the old MD.
