Researchers from Flinders University and Flinders Medical Centre have identified a crucial link between two common types of bowel polyps, adenomas and serrated polyps, and an increased risk of cancer. Their findings were published in the journal Clinical Gastroenterology and Hepatology (CGH).

Risk Factor Analysis

A review of over 8,400 colonoscopy records revealed that individuals with both adenomas and serrated polyps are at a significantly higher risk of developing advanced precancerous changes. This risk was found to be up to five times greater compared to those who had only one type of polyp.

"Polyps are common and usually harmless, but when both types appear together – what we call synchronous lesions – the risk of serious bowel disease or cancer rises sharply," says Dr. Molla Wassie, lead author and researcher at the FHMRI Bowel Health Service.

Implications

The study highlights the importance of screening strategies and follow-up colonoscopy schedules that reflect differences between polyp types. It also underscores the significance of early detection and regular monitoring, especially for individuals who have both adenomas and serrated polyps.

Recommendations

Individuals over age 45 or those with a family history of bowel disease are encouraged to speak with their GP or visit the National Bowel Cancer Screening Program to learn about available screening options. Regular colonoscopy screening is crucial for polyp detection and removal, reducing the risk of cancer development.
