Colorectal Cancer: Why Screening at 45 is Becoming the New Standard
A growing chorus of medical professionals and advocacy groups are urging a shift in colorectal cancer screening guidelines, recommending that individuals at average risk begin regular screenings at age 45, rather than the current 50. This change comes as evidence mounts showing a concerning rise in diagnoses among younger adults.
The Rising Tide of Early-Onset Cases
For decades, colorectal cancer was largely considered a disease of older adults. However, that narrative is changing. According to Barry Stein, president and CEO of Colorectal Cancer Canada, Canadians born after 1980 are now two and a half times more likely to be diagnosed with colorectal cancer before the age of 50 compared to previous generations. This alarming trend is prompting a reevaluation of current screening protocols.
The Canadian Cancer Society is now advocating for provincial and territorial programs to include individuals as young as 45. This recommendation applies to those without a family history of the disease, highlighting the increasing risk for the general population.
What Does Screening Involve?
Currently, the most common method of colorectal cancer screening involves stool tests. These tests are a non-invasive way to detect early signs of the disease. If abnormalities are found, a colonoscopy may be recommended for further investigation.
Personal Stories Fuel the Call for Change
The push for earlier screening isn’t just based on statistics; it’s driven by the real-life experiences of those affected. Steve Slack, of Bowmanville, Ontario, was 46 when he first experienced symptoms, but wasn’t diagnosed until age 49. His story underscores the challenges faced by younger individuals who may not be considered for screening.
Slack’s initial symptoms were dismissed as food sensitivities. However, when blood appeared in his stool, he sought immediate medical attention. The diagnosis revealed a large tumor and subsequent discovery of metastatic tumors on his liver. After successful treatment, including surgery and chemotherapy, Slack is now cancer-free, but his experience highlights the devastating consequences of delayed diagnosis.
The recent passing of actor James Van Der Beek at age 48, after a battle with Stage 3 colorectal cancer, and Chadwick Boseman at age 43, further emphasize the urgency of this issue.
Why the Shift? Global Trends and Expert Opinions
Canada isn’t alone in considering this change. Several countries, including Australia, Japan, Taiwan, and the United States, have already lowered their screening age in response to emerging evidence. Dr. Shady Ashamalla, a surgeon at Sunnybrook Hospital in Toronto, believes Canada is overdue to follow suit.
“It is not a disease of the elderly anymore,” Dr. Ashamalla stated. Early detection is crucial, as colorectal cancer is highly curable when caught in its initial stages. However, when younger patients aren’t screened or ignore symptoms, the disease can progress to more advanced and difficult-to-treat stages.
Improving Access to Screening
Beyond lowering the screening age, advocates are also emphasizing the require to improve access to screening programs. Currently, access often depends on having a family doctor. The Canadian Cancer Society recommends that individuals be able to request screening at clinics or through provincial programs, regardless of their access to a primary care physician.
