Comprehensive services & treatments

The gastroenterology specialists at the Advocate Good Samaritan Hospital Digestive Health Center work to prevent and treat a range of gastrointestinal tract diseases using the most minimally invasive and innovative procedures.

Colonoscopy: catch cancer signs early

A screening colonoscopy can detect colon cancer in its early stages, when it's very treatable. You should get a colonoscopy every 10 years, beginning at age 45. Depending on your family history and other potential risk factors, you may need earlier or more regular screening.

A simpler process: We offer direct access to screening colonoscopies to qualified patients, saving you time and money.

Don’t worry: What you should know about your first colonoscopy.
