Check Eligibility & AvailabilityWhy Colonoscopy Matters
Colon cancer is highly treatable when found early.

Early detection saves lives.
What to Expect
Before Your Appointment
You'll receive simple prep instructions. Our staff reviews everything with you so you feel prepared and supported.
During the Procedure
You'll have gentle sedation for comfort while Dr. Lyons performs a careful, thorough screening using modern techniques.
Afterward
You'll rest briefly, then return home the same day. Most patients feel normal later that evening.
Comfort & Prep
Most patients say prep was easier than they expected.
We provide straightforward instructions and support so you feel confident and comfortable.
Colonoscopy vs Stool Tests
Some patients consider stool tests like Cologuard. These tests can be useful, but:
| Screening | Detects Polyps | Removes Polyps | Frequency | Accuracy |
|---|---|---|---|---|
| Colonoscopy | Yes | Yes | Every 10 yrs (for most) | Highest |
| Stool tests | No | No | Every 1–3 yrs | Lower |
Colonoscopy is the gold standard for prevention and early detection.
Insurance & Cost
Most insurance plans and Medicare typically cover preventive colonoscopy screenings.
We verify benefits and explain any costs before scheduling.
No surprises, no confusion.
