The Cologuard test is designed to detect cancer not prevent it. Cologuard can only detect 42% of large polyps, while a colonoscopy can detect 95% of large polyps. When polyps are detected during a colonoscopy they are removed at the same time.Mar 24, 2020
Which is better colonoscopy or cologuard?
Cologuard vs Colonoscopy According to GI Alliance, Cologuard can miss up to 8% of colon cancer and more than 50% of pre-cancerous polyps. Stool DNA (Cologuard) testing is designed to detect and not prevent cancer. A colonoscopy is the only test that both detects and prevents colon cancer.
Can I use cologuard instead of a colonoscopy?
Cologuard is not intended to replace diagnostic colonoscopy or surveillance colonoscopy in high-risk patients, including those with inflammatory bowel disease (IBD).
Is cologuard good enough?
Just how good is Cologuard? Based on the one major study cited,(6) it is pretty darned good: Cologuard detected 92% of colorectal cancers and 42% of advanced polyps. As a comparison, the FIT test detected 74% of cancers and 24% of advanced polyps.
Does cologuard detect benign polyps?
These stool-based tests are limited in their ability to detect polyps, and they do not differentiate between cancer and benign polyps. This can result in a positive stool test that creates unnecessary worry.
Who should not use cologuard?
Cologuard was not clinically evaluated for the following types of patients: Patients with a history of colorectal cancer, adenomas, or other related cancers. Patients who have had a positive result from another colorectal cancer screening method within the last 6 months.
Should I be worried about positive cologuard?
There is no risk involved in taking the sample for Cologuard test. Screening tests carry a small risk of: False-positives (your test results are abnormal, but you do NOT have colon cancer or pre-malignant polyps) False-negatives (your test is normal, even when you have colon cancer)
Should I worry if my cologuard is positive?
There is no risk involved in taking the sample for Cologuard test. Screening tests carry a small risk of: False-positives (your test results are abnormal, but you do NOT have colon cancer or pre-malignant polyps) False-negatives (your test is normal, even when you have colon cancer)
What do gastroenterologists think of cologuard?
I feel most gastroenterologists would agree Cologuard is a potent weapon in the armamentarium against colon cancer. The 92 percent sensitivity for CRC, and 69 percent sensitivity for detection adenomas with high grade dysplasia, make it the standard second line option, next to colonoscopy.
How long is Cologuard good for?
How often do you need to repeat the test – Cologuard must be repeated every three years if you've never had a positive result. Once you have had a positive result, you will need to have diagnostic colonoscopies for further screening exams.
