colon cancer: Cancer society officials acknowledge the shift to 45 could cause confusion for doctors and patients but felt strongly that they needed to act now, according to CTV. The advocacy group was influenced by its study, published last year, that found rising rates of colon cancer and deaths in people younger than 50. The American Cancer Society's advice puts it out of sync with guidelines from an influential government advisory group, which kept the age at 50 in an update two years ago. Experts aren't sure why there has been a 50 per cent increase in cases since 1994. The group endorses six kinds of screening exams, from inexpensive take-home stool tests performed every year to colonoscopies done every 10. The guidelines are for men and women ages 45 to 75 of average risk for colon cancer; recommendations are different for people with certain conditions, like Crohn's disease, or a family history of colon cancer.
