Kentucky's largest health system is contributing $100,000 to the Kentucky Cancer Foundation to support colon cancer screenings. KentuckyOne Health said yesterday the gift will support screenings for low-income, uninsured Kentuckians between ages 50 and 64. Crit Luallen, a cancer foundation board member, says more screenings will save lives. Luallen is a colon cancer survivor. Kentucky has the nation's second-highest rate of colon cancer. The Centers for Disease Control and Prevention says the five-year survival rate for colon cancer is 90 percent when found and treated early. Over the past two years, Gov. Steve Beshear and state lawmakers committed $1 million through June 2014 to 10 health departments to expand colon cancer screening services for Kentuckians at risk. Beshear challenged the cancer foundation to raise matching funds for the program.
