Radiation Therapy & Gamma Rays: How They Treat Cancer

Yes, radiation therapy uses gamma rays (among other radiation types) to treat cancer and other conditions. Gamma rays are high-energy electromagnetic radiation emitted by radioactive decay (e.g., cobalt-60) or generated by linear accelerators.

How Gamma Ray Therapy Works

• Precision targeting: Beams are focused on tumors with millimeter accuracy, sparing healthy tissue.
• Deep penetration: Gamma rays traverse the body effectively, ideal for deep-seated tumors.
• Delivery methods:
  • External Beam Radiation Therapy (EBRT): Machine outside body directs beams at tumor.
  • Brachytherapy: Radioactive sources placed inside/near tumor for localized high-dose delivery.

Treatment Planning

Radiation oncologists meticulously calculate dose, duration, and beam angles to maximize cancer cell destruction while minimizing collateral damage. Gamma ray therapy is a well-established, widely used cornerstone of cancer treatment.
