Answer 1

Radiation therapy is a local treatment that can destroy cancer cells with minimal damage to surrounding tissue.

Step-by-step explanation:

Radiation therapy is a local treatment that can destroy cancer cells with minimal damage to surrounding tissue. It uses ionizing radiation, such as X-rays, to kill cancerous tissues. Multiple rays are directed toward the cancer from different angles, intersecting at the site of the cancer and providing a higher dose of radiation to the cancer cells compared to the surrounding healthy tissue.
