Death of actor James Van Der Beek underscores colon cancer screening and detection

The death of actor James Van Der Beek at 48 has renewed discussion of rising colorectal cancer among Canadians under 50; a Toronto colorectal surgeon described screening options and common risk factors.

The recent death of actor James Van Der Beek at 48 has renewed public discussion of colorectal cancer in Canada. Experts report that incidence has been rising among Canadians younger than 50. Sami Chadi, a colorectal surgeon at Toronto's University Health Network, spoke with The Globe and Mail about detection, screening options and risk factors. Key facts: - Colorectal cancer refers to a tumour or malignancy in the colon or rectum, the end of the gastrointestinal tract. - Common signs noted include visible or microscopic blood in stool, thinning or changes in bowel movements, and unexplained anemia. - Screening options discussed include stool-based tests, colonoscopy (a camera on a thin tube under sedation), and CT-based "virtual" colonoscopy. Polyps are precancerous growths that can be removed during colonoscopy. - Risk factors include environmental influences such as high alcohol intake, smoking, high-fat and low-fibre diets and sedentary lifestyle, and genetic conditions like Lynch syndrome, which account for about 10–15% of cases; Dr. Chadi also said many people may need to increase soluble fibre intake toward about 25–30 grams per day. Summary: The conversation following Mr. Van Der Beek's death highlights concerns about rising colorectal cancer among younger adults and focuses attention on screening methods and known risk factors. Undetermined at this time.
