ST. LOUIS (KMOX) - The answer to your risk of getting a major disease could be found in the palm of your hand.

Washington University researchers, led by Dr. Graham Colditz, have developed a free iPad app that offers a quick risk assessment for six major diseases.

“Heart disease, stroke, diabetes, lung cancer, colon cancer, and - for women - breast cancer, for men – prostate cancer,” Colditz said.

Following the risk assessment, based on a series of questions, the app then offers tips for how to lower your disease risk.

“It really works simply by entering a short set of answers to questions on smoking, weight, height, activity and diet,” Colditz explained. “And, from that set of questions, it estimates future risk of these diseases.”

You can get the app, called Zuum, on iTunes.
