A tumor that remains localized and does not invade surrounding tissues is described as:

• A. Malignant
• B. Benign
• C. Metastatic
• D. Invasive

Answer: (B)

Benign tumors are localized and non-invasive. They stay in one place, are usually well-defined or encapsulated, and do not invade surrounding tissues or spread to distant sites. Because they remain local, they’re often removable with a good prognosis, though they can cause problems if they press on nearby structures. Malignant tumors invade nearby tissues and can metastasize to other parts of the body, which is why they’re more dangerous. Invasive describes the behavior of malignant tumors toward surrounding tissues, while metastatic refers to spreading to distant sites. So, a tumor that stays put and doesn’t invade is described as benign.
