New research has revealed that having two specific types of intestinal polyps together — adenomas and serrated polyps — can increase the risk of bowel cancer by up to five times. These growths are found in the colon or intestine and are usually harmless at first, but some can slowly turn cancerous over time.
The study, conducted by researchers at Flinders University, analyzed more than 8,400 colonoscopy records. Researchers found that people who had both kinds of polyps at the same time faced a much higher risk of advanced precancerous changes compared to people with only one type.
Key findings from the research:
- The dangerous combination is called synchronous lesions.
- Nearly half of patients with serrated polyps also had adenomas.
- Serrated polyps may develop into cancer faster than regular adenomas.
- Early detection through colonoscopy can help remove these polyps before cancer develops.
Doctors say regular screening is especially important for:
- People above 45 years of age
- Those with a family history of bowel cancer
- Individuals with previous polyps or digestive problems
Symptoms that should not be ignored include:
- Blood in stool
- Persistent constipation or diarrhea
- Unexplained weight loss
- Ongoing stomach pain or bloating
The study reinforces that routine colonoscopy screening and timely treatment can significantly reduce the risk of colorectal cancer.
