Final answer:
A benign tumor consists of cells that are confined to their original location and do not invade nearby tissues, unlike malignant tumors. Benign tumors are not cancerous, do not spread to other body parts, and can typically be removed surgically without major health risks.
Step-by-step explanation:
A benign tumor is made up of cells that are confined to the local area and do not spread to other parts of the body. These tumors are not cancerous and do not invade neighboring tissues or organs. Unlike malignant tumors, which continue growing and can spread throughout the body, benign tumors generally remain localized and can often be removed without harming the person's health.
Localized cancer is limited to the place where it started and shows no sign of spreading beyond the local tissue. This is different from a benign tumor, as localized cancer may still be dangerous due to its potential to become invasive. In contrast, benign tumors do not invade other tissues and typically do not form metastases, therefore not posing the same health risk as malignant or even localized cancers.
