Colorectal Cancer Canada is advocating for a significant shift in the age at which routine screening for colorectal cancer begins, proposing a reduction from the current threshold of 50 to 45 years for average-risk Canadians. This recommendation comes in light of alarming trends indicating a rise in colorectal cancer diagnoses among younger adults. The organisation’s recent press release emphasises that this adjustment is crucial as the incidence of the disease continues to climb, particularly among individuals aged 45 to 49.
Rising Incidence Among Younger Adults
A research letter from the American Cancer Society published in January revealed that colorectal cancer has become the leading cause of cancer-related deaths in individuals under 50 in the United States. This troubling trend is mirrored in Canada, where the Canadian Cancer Society has also reported increasing rates of this disease among younger populations. Projections suggest that by 2025, colorectal cancer is set to become the fourth most commonly diagnosed cancer in the country and the third leading cause of cancer mortality for both men and women.
The Canadian Cancer Society anticipates that approximately 26,400 new cases of colorectal cancer will be diagnosed in 2025, with an estimated 9,100 fatalities attributed to the disease. This statistic highlights that colorectal cancer accounts for a staggering 10 percent of all new cancer cases and deaths recorded in the previous year.
Screening Access and Awareness
Despite the rising number of cases, provincial screening programmes continue to enforce a starting age of 50, leaving a significant portion of the population without access to essential screening services. Brandon Purcell, the advocacy manager for prevention and early detection at the Canadian Cancer Society, underscored the importance of lowering the screening age. He stated, “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.”

Dr. Harminder Singh, a gastroenterologist based in Manitoba, echoed these sentiments, highlighting the barriers to screening that cannot be overlooked. He noted, “The trend is increasing in all younger age groups; the rates may be lower than among older individuals, but this issue needs greater attention and awareness.” Dr. Singh also pointed out that individuals with a family history of colorectal cancer require heightened scrutiny, as the current detection rates remain suboptimal.
Government Action on Cancer Research
In a related development, Health Minister Majorie Michel announced on Thursday that the federal government is allocating $41 million towards the establishment of 19 new cancer research teams. These teams will focus on innovative approaches to preventing various types of cancers, including colorectal, lung, breast, and prostate cancers. Part of this initiative involves collaboration with Japanese researchers to examine the connections between ageing and the emergence of early-onset colorectal and pancreatic cancers.
Dr. Singh emphasised the importance of awareness in cancer screenings, stating, “Raising awareness is a personal choice that requires discussion around decision-making. It is vital for individuals to understand the potential benefits and any risks, however minimal, associated with screening options.”
Why it Matters
The push to lower the colorectal cancer screening age to 45 is not merely a matter of policy change; it reflects a deepening understanding of the disease’s evolving demographics. As more young Canadians are diagnosed with colorectal cancer, it becomes imperative to adapt our healthcare frameworks to ensure timely access to screenings. Ignoring this vital issue risks leaving a vulnerable population without crucial early detection opportunities, ultimately impacting survival rates and quality of life. It is essential for health authorities to consider this recommendation seriously, prioritising proactive measures to safeguard the health of younger Canadians.
