Cologuard vs Colonoscopy
How accurate is Cologuard?
Performance numbers
According to a largescale clinical study, Cologuard detects about92% of colorectal cancers and 69% of advanced precancerous polyps. While not as exhaustive as a colonoscopy, these figures make it a solid screening option for averagerisk adults.
When should I choose colonoscopy instead?
Highrisk scenarios
If you have a strong family history of colorectal cancer, a personal history of inflammatory bowel disease, or previous abnormal screening results, your doctor will likely recommend a colonoscopy. It allows direct visualization and immediate polyp removal.
Can I do both?
Using Cologuard as a first step
Many physicians use Cologuard as a noninvasive preliminary screen. If the results are positive, a followup colonoscopy is scheduled to investigate further. If you have digestive conditions like IBS, consider reading more about intermittent fasting IBS with your clinician before testing, since recent diet changes can affect stool characteristics.
