Colorectal Cancer Canada is advocating for a significant policy shift, urging provinces and territories to lower the routine screening age for colorectal cancer from 50 to 45 for average-risk Canadians. This recommendation comes amid alarming trends showing rising incidence rates of the disease among younger adults, and experts stress that immediate action is required to address this growing public health concern.
Rising Rates Among Younger Adults
A recent press release from Colorectal Cancer Canada highlights the urgent need for change, pointing to an American Cancer Society research letter which identified colorectal cancer as the leading cause of cancer-related deaths in individuals under 50 in the United States. This troubling trend is echoed in Canada, where the incidence of colorectal cancer is steadily increasing in the 45 to 49 age bracket.
In November, the Canadian Cancer Society projected that colorectal cancer would become the fourth most commonly diagnosed cancer in the country by 2025. The report estimated that around 26,400 Canadians would receive a colorectal cancer diagnosis this year, with approximately 9,100 expected fatalities attributed to the disease. This sobering statistic represents 10 per cent of all new cancer cases and deaths in Canada during the previous year.
Current Screening Practices
Despite the rising number of diagnoses, provincial screening programmes have yet to adapt, continuing to initiate routine screenings at age 50. This leaves a vulnerable population without access to essential early detection services. Brandon Purcell, the advocacy manager for prevention and early detection at the Canadian Cancer Society, emphasised the importance of early detection, stating that lowering the screening age could lead to more cancers being identified at a stage when they are more manageable and treatable.
Dr. Harminder Singh, a gastroenterologist from Manitoba, echoed these sentiments, stressing that the barriers to screening cannot be overlooked. He noted that while the rates of colorectal cancer in younger age groups are comparatively lower than those in older demographics, the situation warrants greater attention and awareness.
The Role of Family History
Family history plays a crucial role in cancer risk, and Dr. Singh highlighted the need for increased vigilance among individuals with a familial predisposition to colorectal cancer. He pointed out that those with a family history of cancer syndromes often face suboptimal detection rates. Heightening awareness of these risks can help ensure that at-risk individuals receive the necessary screenings and preventive measures.
Federal Government’s Commitment
In a related development, Health Minister Majorie Michel announced a federal investment of £41 million aimed at establishing 19 new cancer research teams focused on innovative prevention strategies for various cancers, including colorectal cancer. This initiative includes collaboration with Japanese researchers to explore connections between ageing and early-onset colorectal and pancreatic cancers.
Dr. Singh concluded by reiterating the need for increased awareness of cancer screenings. He advocates for open discussions regarding decision-making around screenings, suggesting that individuals should be informed about both the potential benefits and risks associated with colorectal cancer screening.
Why it Matters
The call to lower the colorectal cancer screening age is not just a statistic; it represents a crucial step towards saving lives. By recognising the rising incidence of colorectal cancer among younger Canadians, health authorities can implement proactive measures that could significantly improve outcomes. Early detection is vital in the fight against cancer, and making screenings accessible to younger populations can lead to timely interventions that enhance survival rates. In an era where preventative health measures are paramount, this recommendation could transform the landscape of colorectal cancer care in Canada, ultimately benefitting countless individuals and families.
