Should I worry about a positive Cologuard test?
Abnormal result (positive result) suggests that the test found some pre-cancer or cancer cells in your stool sample. However, the Cologuard test does not diagnose cancer. You will need further tests to make a diagnosis of cancer. Your provider will likely suggest a colonoscopy.
What percentage of positive Cologuard tests are 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.
What would cause a positive Cologuard test?
If you receive a positive result on your Cologuard test, it is likely that you already have colorectal cancer or pre-cancerous colon polyps that are causing bleeding. False positive results are common with non-colonoscopy screening tests.
Does a positive stool test mean cancer?
The test isn’t always accurate.
It’s possible for a stool DNA test to show signs of cancer, but no cancer is found with other tests. Doctors call this a false-positive result. It’s also possible for the test to miss some cancers, which is called a false-negative result.

Is a positive Cologuard test always mean cancer?
A positive result does not necessarily mean a patient has cancer. It means that Cologuard detected DNA and/or hemoglobin biomarkers in the stool that are associated with colorectal cancer or advanced adenoma. False positives and false negatives occur with Cologuard, and appropriate follow-up is important.

What happens if you test positive for colon cancer?

New federal guidance released in January will soon require health insurance plans to fully cover the cost of a follow-up colonoscopy to evaluate a positive result from an MTs-DNA stool-based test (Cologuard) as well as a fecal immunochemical test (FIT).
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.

Polyps removed during colonoscopy are sent to a laboratory for analysis to determine whether they are cancerous, precancerous or noncancerous. Depending on the size and number of polyps, you may need to follow a more rigorous surveillance schedule in the future to look for more polyps.
What is the next step after a positive fit test?
FIT is one of the most widely used colorectal cancer screening tests worldwide. Experts generally recommend that people repeat this test every 1 to 2 years. People with a positive FIT test result are advised to have a colonoscopy to investigate the cause of the bleeding because a FIT test alone cannot diagnose cancer.
How long does it take for bowel cancer to spread?
Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years. Once cancer has developed in the colon, its progression will vary according to the cellular makeup of the tumor and other factors, such as the age and overall health of the patient.
