Colon Cancer Screening Options

Colonoscopy
When it comes to screening for colorectal cancer, a colonoscopy is the gold standard of care. A colonoscopy is an outpatient endoscopic procedure performed by a gastroenterologist to examine the inside of your colon. During this procedure, a small camera at the end of a long, flexible tube is inserted through the anus and advanced through the colon. If polyps (precancerous growths) are found, they can be removed, so they do not turn into colon cancer.
In addition to screening for colon cancer, your colonoscopy provides a visual of your overall gut health and gives your care team insight into ways to care for your unique gastrointestinal health needs.

Computed Tomography (CT) Scan
A CT scan creates and captures 3D images of the colon, allowing the physician to detect any abnormalities. If abnormalities are detected, your gastroenterologist will order a colonoscopy for further testing.

Stool-Based Testing
Depending on insurance coverage, your gastroenterologist may order stool-based tests such as a fecal immunochemical test (FIT) or a stool DNA test to screen for colorectal cancer.
A fecal immunochemical test detects microscopic amounts of blood in the stool, and a stool DNA test analyzes the stool for generic changes that may indicate cancer. If either test comes back positive, a colonoscopy will still be required.
