How Is Radiation Therapy Administered?

Radiation therapy can be administered in several ways, depending on the type and location of the cancer:

  • External Beam Radiation Therapy (EBRT): Delivered from a machine outside the body, targeting the cancer site.
  • Internal Radiation Therapy (Brachytherapy): Involves placing radioactive material inside the body near the cancer cells.
  • Systemic Radiation Therapy: Involves swallowing or injecting radioactive substances that travel throughout the body.
  • Stereotactic Radiosurgery: A precise form of radiation therapy that targets tumors in the brain and other parts of the body with high doses of radiation.

The choice of method depends on the specific type and location of the cancer being treated.
