Medicare pays for colorectal screening, but that federal insurance program is for people 65 and older, a long wait for the low-income 50-year-old with no insurance.
Enter the CDC's new free-screening project, the first major federal effort to target that population - and one that, if it works, might one day be expanded nationwide.
Participants in Suffolk County, N.Y., and Baltimore will receive colonoscopies, where doctors use a long, flexible tube to visually inspect the colon. In three other sites - St. Louis, Seattle/King County, Wash., and statewide in Nebraska - most participants will receive at-home fecal tests to detect hidden blood in the stool.
Colonoscopies are more expensive, $700 to $1,000, and require a day at the doctor's office and more intense preparation, but they're needed only once every 10 years. The fecal occult blood test is needed annually but is simpler to perform and much cheaper, $10 to $20.
Recent public education campaigns have largely focused on colonoscopies, such as when host Katie Couric underwent one on NBC's "Today" show. But for the average person, the fecal test is just as effective, so consumers need to understand they have a choice, says Nebraska program director Melissa Leypoldt.
Beyond price is how to reach those most at risk to tell them to get screened. It's not clear how well doctors urge colorectal screening, and those who need the message may not see a doctor regularly anyway.
"We have to make an impact somewhere outside of the doctor office," stresses Morehouse's Blumenthal, who is enlisting black ministers in his own CDC-funded research on ways to counter colorectal cancer's racial disparity.
A doctor's advice may be easier to shrug off than hearing how someone you respect professionally or socially fought this disease, adds William Murrain, a Morehouse colleague and health-care consultant from Conyers, Ga., who survived colorectal cancer in 2002 - and has since recruited dozens of members of his Rotary and scuba-diving clubs to get tested.
Murrain, now 61, had gotten an exam called a sigmoidoscopy two years earlier, but it only inspects the bottom portion of the colon for cancer, and thus missed his tumor.
"You don't tend to think it would affect you ... until somebody brings it home to you, says, 'I'm a cancer survivor.'"
