The correct term to complete the sentence is:benign

Benign tumors are growths that typically remain localized to their original site and do not invade surrounding tissues or spread to other parts of the body. These tumors are usually well-defined and slow-growing. While benign tumors may cause local pressure effects and impair function depending on their location, they generally do not cause significant damage or pose a threat to life. Unlike malignant tumors, benign tumors do not have the ability to metastasize or spread to distant sites in the body.
