Startup lets doctors classify skin conditions with the snap of a picture

At the age of 22, when Susan Conover wanted to get a strange-looking mole checked out, she was told it would take three months to see a dermatologist. When the mole was finally removed and biopsied, doctors determined it was cancerous. At the time, no one could be sure the cancer hadn't spread to other parts of her body -- the difference between stage 2 and stage 3 or 4 melanoma. Thankfully, the mole ended up being confined to one spot. But the experience launched Conover into the world of skin diseases and dermatology.
