Advocacy group urges Canada to lower starting age for colorectal-cancer screening

Canada should lower the starting age for colorectal-cancer screening to 45 from 50 because rates of the disease are rising among younger patients, according to a prominent cancer advocacy group. Colorectal Cancer Canada will unveil a campaign Tuesday calling on provinces and territories to promote and provide stool tests to people beginning five years earlier than is the practice today, after similar advice from the United States and Australia.
