Colorectal Cancer Canada is calling on provincial and territorial governments to lower the routine screening age for colorectal cancer from 50 to 45 for average-risk Canadians. This recommendation, announced in a press release on Thursday, comes in response to alarming trends indicating a rise in colorectal cancer cases among younger adults. Health experts assert that this adjustment is urgently needed to address the increasing prevalence of the disease.
Rising Rates of Colorectal Cancer in Younger Populations
A recent letter published by the American Cancer Society revealed that colorectal cancer has emerged as the leading cause of cancer-related mortality among individuals under 50 in the United States. This trend is echoed in Canada, where incidence rates are climbing among adults aged 45 to 49. The Canadian Cancer Society has projected that by 2025, colorectal cancer will rank as the fourth most commonly diagnosed cancer in the country and the third leading cause of cancer deaths for both men and women.
The report estimates that in the preceding year, approximately 26,400 Canadians were diagnosed with colorectal cancer, with 9,100 succumbing to the disease. This alarming statistic represents 10 per cent of all new cancer cases and deaths within the country. Despite these figures, all provincial screening programmes continue to initiate screening at age 50, leaving a significant population at risk without access to essential routine examinations.
Advocacy for Early Detection
Brandon Purcell, Advocacy Manager for Prevention and Early Detection at the Canadian Cancer Society, emphasized the importance of early detection, stating that a lower screening age would facilitate the identification of cancers at a stage when they are more amenable to treatment and survival rates are markedly improved.
Dr. Harminder Singh, a gastroenterologist based in Manitoba, echoed these sentiments. He highlighted the barriers surrounding screening that cannot be overlooked. While the rates of colorectal cancer in younger age groups are lower than in older populations, the need for increased awareness and attention is critical. Dr. Singh also pointed out the necessity of focusing on individuals with a family history of colorectal cancer, as their detection rates remain suboptimal. He stressed that raising awareness about familial cancer syndromes could significantly benefit those at risk.
Government Response and Research Investment
In a related development, Health Minister Marjorie Michel announced on Thursday that the federal government will invest $41 million into 19 new cancer research teams. This funding aims to explore innovative strategies for preventing various cancers, including lung, breast, prostate, and colorectal cancers. Part of this initiative involves collaboration with researchers from Japan to deepen the understanding of the connections between ageing and early-onset colorectal and pancreatic cancers.
Dr. Singh reiterated the crucial role of awareness in cancer screenings. “Raising awareness is an individual choice, and it is vital to foster discussions around decision-making,” he said. “People must be informed of the potential benefits and any risks, however minimal, associated with screenings. Ultimately, awareness of available options is paramount.”
Why it Matters
The recommendation to lower the colorectal cancer screening age could be a pivotal step in addressing the rising incidence of this disease among younger Canadians. By facilitating earlier detection, healthcare systems can improve treatment outcomes and potentially save lives. As the statistics reveal a growing at-risk population, it is imperative that provincial and territorial governments respond swiftly to safeguard public health. The future of cancer care in Canada may very well depend on proactive measures that prioritise awareness and accessibility for all age groups.
