PathologyTumour cells have genetic alterations which result in expression of nonself proteins: This is the most accurate statement regarding immune surveillance. Tumor cells often undergo genetic mutations that lead to the expression of abnormal proteins (neoantigens) that are not present in normal cells. These nonself proteins can be recognized by the immune system as foreign, triggering an immune response. This recognition is a key aspect of how immune surveillance functions effectively against tumors.
