Colonoscopy is associated with lowered risk of colorectal cancer occurrence and mortality. In a recent study published in the journal Gastroenterology researchers set out to find specific evidence of the effects of screening colonoscopies.
The researchers found:
• History of colonoscopy was associated with reduced CRC risk independent of the examination indication.
• History of colonoscopy had stronger association with reduced CRC risk in examinations with screening indications, opposed to examinations with diagnostic indications.
• Colonoscopy was associated with reduced risk of cancer in the right colon regardless to indication for the exam.
• Colonoscopy reduced the risk of CRC up to 10 years after colonoscopy, for any indication.
