검증된 단계별 안내1
Understand the definition of a benign tumor: A benign tumor is a non-cancerous growth of cells that does not invade surrounding tissues or spread to distant sites (metastasize).
Compare benign tumors to malignant tumors: Malignant tumors are cancerous, composed of abnormal cells, and can invade nearby tissues and metastasize to other parts of the body. Benign tumors lack these aggressive characteristics.
Evaluate the statement 'They do not invade surrounding tissues or metastasize to distant sites': This is true for benign tumors, as they remain localized and do not spread.
Analyze the statement 'They are composed of undifferentiated, highly abnormal cells': This is false for benign tumors, as their cells are typically more differentiated and resemble normal cells compared to malignant tumors.
Review the remaining statements: 'They are always life-threatening and rapidly spread throughout the body' and 'They typically cause extensive damage to distant organs' are both false for benign tumors, as they do not spread or cause damage to distant organs.
