What's the hardest part of a colonoscopy?

Most people find the prep — the bowel-clearing process the day before — more challenging than the procedure itself, since sedation keeps you comfortable and typically unaware during the actual colonoscopy.

At what age should I start colorectal cancer screening?

Screening is generally recommended starting at age 45 for average-risk adults, though your doctor may recommend earlier or more frequent screening based on your specific risk factors and family history.

Q: Is Cologuard as good as a colonoscopy?

Cologuard is a reasonable non-invasive option for average-risk adults, but it's less sensitive than colonoscopy, and any positive result still requires a follow-up colonoscopy to investigate further.

Prep anxiety is the number one barrier to colorectal cancer screening. Tell us how many days until your procedure, and get a clear, day-by-day countdown checklist to make prep easier.

The essentials

Prep anxiety is the #1 barrier to a screening that saves lives

Colonoscopy remains one of the most effective colorectal cancer screening tools, yet prep anxiety keeps many people from scheduling or completing the procedure.

A clear countdown reduces the unknown

Breaking prep down into a day-by-day checklist transforms a vague, anxiety-inducing process into a series of manageable steps.

Alternatives exist for some people

Cologuard offers a non-invasive option for average-risk adults, though it's less sensitive than colonoscopy and any positive result still requires a follow-up colonoscopy.

Sedation makes the procedure itself far easier than most expect

Most patients are comfortable and largely unaware during the actual procedure, with the prep being the part that requires the most preparation and patience.

Key takeaway

Colonoscopy prep anxiety is real but manageable with a clear countdown checklist, and understanding your screening options — including Cologuard as an alternative for some — helps you make an informed choice about colorectal cancer screening.
