Colorectal cancer screening should start at age 45, organization says
Global News
Colorectal Cancer Canada has recommended provinces and territories commit to lowering the routine colorectal cancer screening age for average-risk Canadians from 50 years of age.
Colorectal Cancer Canada is recommending provinces and territories should “commit to lowering the routine colorectal cancer screening age to 45 for average-risk Canadians.”
Thursday’s press release argues that lowering the screening age from 50 is “a change experts say is urgently needed to reflect rising rates of the disease among younger adults.”
An American Cancer Society research letter released in January also highlighted that colorectal cancer is now “the leading cause of cancer-related death among individuals under the age of 50 in the United States.”
This trend is mirrored in Canada with incidence rates steadily increasing among adults aged 45 to 49.
The Canadian Cancer Society reported in November that colorectal cancer was expected to be the fourth most commonly diagnosed cancer in Canada in 2025, and the third leading cause of death from cancer in both men and women.
The report estimated that 26,400 people in Canada will be diagnosed with colorectal cancer and 9,100 patients would die of the disease, representing 10 per cent of all new cancer cases and deaths last year.
Colorectal Cancer Canada reported that despite the rise in diagnoses, “all provincial screening programs still begin at age 50, leaving a growing at-risk population without access to routine, organized screening.”
Brandon Purcell, advocacy manager of prevention and early detection at the Canadian Cancer Society, said in an emailed statement to Global News that, “a lower screening age for colorectal cancer will catch more cancers early when they are easier to treat and the likelihood of survival is much higher.”
