The recommended follow-up colonoscopy interval for patients with a history of colorectal cancer after curative surgical resection is typically set at 1 year. This timing is crucial because it allows for early detection of any new polyps or recurrence of cancer, which can significantly impact the patient's prognosis and management options.

Patients with a history of colorectal cancer are at increased risk for developing new cancers or advanced adenomas, and performing a colonoscopy 1 year after surgery is aligned with guidelines that emphasize the importance of close monitoring during the initial years following treatment. This approach helps to ensure any potential complications or recurrences are identified promptly, allowing for timely intervention.

Subsequent follow-up colonoscopies may then be extended to longer intervals based on findings from the initial post-operative colonoscopy and the patient's overall risk profile.
