while rates of colorectal cancer have been decreasing among people aged 50 and older, they’re moving in the opposite direction for patients under the age of 50 and it isn’t clear why, said ng, who is also is the director of the young-onset colorectal cancer center at dana-farber cancer institute. dropping the age requirement by five years will allow millions of people to get screened earlier, saving countless lives, she said.
colorectal cancer is the third-most diagnosed cancer in canada, with just under 27,000 new cases arising in 2020,
according to the canadian cancer society
. it is the second leading cause of death from cancer in men and third in women. roughly 73 canadians receive the grim diagnosis — and another 27 succumb to the disease — every day.
the task force settled on the age of 45 because research reveals the five-year head start will prevent more deaths while introducing minimal increases to potential colonoscopy complications. the task force still recommends selectively screening people between the ages of 76 and 85 because more rigorous testing produces relatively small increases to the lifespan of this age group.
with cases of colon cancer in people aged 20 to 29 years old rising by two per cent each year, and rectal cancer rates up 3.2 per cent among those aged 20 to 29 years old and 30 to 39 years old, the group mulled lowering the age requirement further.
