immune surveillance
immunological surveillance a hypothesized monitoring function by which the immune system protects against cancer; according to the theory, tumor cells constantly arise throughout life by malignant transformation of normal cells but almost all are recognized and destroyed by the immune system, only a few somehow escaping or circumventing immune surveillance to grow and become clinically detectable cancers.
