Summary
This study follows 500 people who had a malignant colorectal polyp removed. Researchers want to learn how often the cancer stays, comes back, or spreads. They will also study how patients and doctors decide on next steps after removal. Participants share medical records and get follow-up calls at 1, 3, and 5 years.

Criteria: * Documentation of Disease * Patients must have one malignant polyp, pathologically confirmed within 90 days of enrollment. Patients with multiple malignant polyps are not eligible. * Definition of Disease Colorectal carcinoma (CRC) develops within serrated or adenomatous polyps. Early CRC represents invasion into the submucosa and frequently presents within the precursor polyp which is termed a 'malignant polyp'(23). The term malignant polyp specifically refers to a colorectal lesion with cancer invading the submucosa but not extending into the muscularis propria. These lesions are classified as pT1 in the TNM classification system (24) Prior Treatment Endoscopic resection of the polypoid lesion-malignant polyp with simple snare polypectomy, conventional endoscopic mucosal resection (EMR), or endoscopic submucosal dissection (ESD) (25). * Age ≥ 18
