Internal radiation therapy:
- Involves injecting, ingesting, or implanting radioactive material inside the body.
- The radiation source is placed directly within or near the tumor, allowing for targeted treatment and reduced damage to healthy tissues.
External radiation therapy:
- Involves directing radiation beams from an external source, such as a linear accelerator or cobalt machine, at the target area.
- The radiation source is positioned outside the body, and the beams are shaped and directed to minimize exposure to healthy tissue.
