Here is an article about a smartphone app and program that may, after more testing, be used as an early screen for pancreatic cancer. As the article mentions, by the time one usually finds out one has pancreatic cancer, it's too late to do much in treatment. Research indicates we have about a 1.6 % chance of getting pancreatic cancer, and with an estimated 64,000 living with it in the U.S.
A good use of a smartphone app, it seems to me. Hope further testing confirms early results.
