Fast Track Screening Colonoscopy

Our physicians provide a service called Fast Track Colonoscopy, which is a regular colonoscopy that does not require prior consultation before the colonoscopy procedure. Fast Track Colonoscopy saves patients time, money, and minimizes work absences for doctor visits. Fast Track is for adults 45 or older with an average risk for colorectal cancer that do not have any existing GI symptoms.
