- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Undergoing standard of care colonoscopy for the evaluation of colonic polyps.~* At least 40 years of age.~* Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).~Exclusion Criteria:~* Pregnant and/or breastfeeding.~* Unable to tolerate sedation.

- Gender: ALL

Study Arms:
- Optical coherence tomography (OCT) probe (Type: EXPERIMENTAL): After consent, the endoscopist will perform a standard of care colonoscopy. If a polyp is found, then OCT will be used to image that polyp. Patients with polyps, regardless of number found, will have either one tubular adenoma (NICE type 2) imaged OR one hyperplastic polyp (NICE type 1) imaged. If no polyps are found, then one area of normal mucosa will be imaged. If on the rare chance a malignant appearing colonic tumor (NICE type 3) is found, this and no other polyps will be imaged with OCT.

Based on this trial design, predict the completion outcome and termination type (if applicable).
