How often should surveillance be performed according to CoC standards?

Surveillance, as per CoC standards, is an ongoing process that should be customized based on each patient's individual needs and circumstances. This flexibility is essential because cancer treatment and patient responses can vary widely. Therefore, the correct approach is to perform surveillance at any scheduled interval deemed necessary by providers. This allows healthcare professionals to monitor the patient's health, adjust treatment plans, and ensure early detection of any recurrence or new issues that may arise.

The other options do not reflect the best practices recommended by the CoC. Relying on surveillance only during initial diagnosis would neglect the importance of ongoing monitoring throughout the patient's journey. Limiting surveillance to only when symptoms arise could lead to missed opportunities for early intervention, which is critical in cancer care. Lastly, suggesting that all patients should be monitored once a year does not take into account the diverse needs of different patients based on their specific conditions, treatment responses, and risk factors. Hence, a flexible, individualized approach is crucial in effective cancer surveillance.
