Cologuard can detect
92% of cancers
and 42% of large precancerous polyps, the precursor to colon cancer.
Can cologuard detect pancreatic cancer?
Cologuard demonstrates that genetic mutations along the digestive tract are detectable in stool.

Can cologuard miss cancer?
Cologuard is not as good at finding pre-cancerous polyps and, unlike colonoscopy, it can’t remove them. According to the NEJM study, Cologuard
misses more than 30 percent of polyps that will soon be cancer
, and 57 percent of polyps that may become cancer.
Can you do cologuard with family history of colon cancer?

If the
Cologuard test
is positive, it may mean that colon cancer or polyps are present. After a positive Cologuard test a colonoscopy is required for a definitive answer. The Cologuard test has a 12% false-positive rate, which means 1 in 10 positive tests will incorrectly identify cancer or polyps.
Can hemorrhoids cause a positive cologuard test?

What does a positive cologuard test really mean?
A positive Cologuard test means that
DNA and/or hemoglobin biomarkers that are associated with colorectal cancer were detected in the stool
. A negative Cologuard test means that Cologuard did not detect significant levels of DNA and/or hemoglobin biomarkers in the stool that are associated with colorectal cancer.
How do I know if I had colon cancer?
Blood in the stool
that is either bright red, black or tarry. Unintentional weight loss. Stools that are narrower than usual. Diarrhea, constipation, or feeling that the bowel does not empty completely.
How can colon cancer be detected without a colonoscopy?
However colonoscopy remains the most sensitive test for colorectal cancer screening and the identification of precancerous polyps.
Stool based tests
, such as Cologuard or FIT, are reasonable alternatives for patients who are unable or unwilling to undergo a standard colonoscopy. Screening saves lives.
How curable is colon cancer?
Cancer of the colon is a
highly treatable and often curable disease when localized to the bowel
. Surgery is the primary form of treatment and results in cure in approximately 50% of the patients. Recurrence following surgery is a major problem and is often the ultimate cause of death.
