Colorectal Cancer Canada is urging provinces and territories to lower the recommended age for routine colorectal cancer screenings to 45 for average-risk Canadians. This significant shift from the current age of 50 comes in light of alarming trends showing increasing rates of the disease among younger adults. A recent study by the American Cancer Society has also identified colorectal cancer as the leading cause of cancer-related deaths among individuals under 50 in the United States, a trend that is being mirrored across Canada.
Rising Incidence Among Younger Adults
The Canadian Cancer Society’s projections indicate that colorectal cancer will become the fourth most commonly diagnosed cancer in Canada by 2025, and the third leading cause of cancer mortality for both men and women. In November, they estimated that 26,400 Canadians would receive a colorectal cancer diagnosis in the coming year, with 9,100 expected to succumb to the illness—accounting for a staggering 10 per cent of all new cancer cases and deaths reported last year.
Despite these increases, provincial screening programmes have not adapted, continuing to initiate screenings only at age 50. Colorectal Cancer Canada emphasises that this leaves a significant population—those aged 45 to 49—without access to critical early detection services.
Expert Opinions on the Need for Change
Brandon Purcell, Advocacy Manager for Prevention and Early Detection at the Canadian Cancer Society, articulated the urgency of this shift: “A lower screening age for colorectal cancer will catch more cancers early when they are easier to treat, significantly increasing the chances of survival.”
Dr. Harminder Singh, a gastroenterologist based in Manitoba, echoed these sentiments, highlighting the barriers that often prevent individuals from getting screened. He noted, “The trend is increasing in all younger age groups. While the rates may be lower than those in older individuals, they require attention and greater awareness.” Additionally, he stressed the need for heightened vigilance among those with a family history of colorectal cancer, underscoring that the detection rates remain suboptimal for this at-risk group.
Government Response and Funding Initiatives
In a related development, Health Minister Majorie Michel announced a federal investment of £41 million in 19 new cancer research teams. This funding aims to explore innovative strategies for preventing various cancers, including colorectal cancer. The initiative also includes collaborative research with Japanese scientists to better understand the connections between ageing and early-onset colorectal and pancreatic cancers.
The government’s commitment to bolstering cancer research is an encouraging step, yet the pressing need for immediate action in screening protocols remains a critical issue for advocates and healthcare professionals alike.
Raising Awareness as a Key Strategy
Dr. Singh emphasised the importance of awareness in the fight against colorectal cancer, stating, “Raising awareness is a personal choice that requires informed decision-making.” He advocates for more discussions around the benefits and potential risks associated with screenings, asserting that public knowledge of available options is crucial.
Why it Matters
The call to lower the screening age for colorectal cancer is not merely a logistical adjustment; it represents a vital public health initiative aimed at saving lives. As incidence rates climb among younger populations, proactive measures for early detection are essential. By shifting screening guidelines, healthcare authorities can ensure that younger Canadians are safeguarded against a disease that has increasingly devastating consequences. Lives can be saved, and quality of life improved, through timely interventions, making it imperative that policymakers act swiftly to enact these changes.
