IGRT Radiation Therapy: What It Is, Uses & Side Effects

Precision in Motion: How Image-Guided Radiation Therapy (IGRT) is Transforming Cancer Care

For decades, one of the greatest paradoxes in radiation oncology has been the challenge of hitting a moving target. Human bodies are dynamic: lungs expand and contract with every breath, bladders fill and empty, and bowels shift naturally over time. Traditional radiation therapy relied heavily on external skin markings and rigid pre-treatment maps, requiring doctors to cast a wide safety net of radiation to ensure they didn’t miss a tumor. Unfortunately, that safety net often caught healthy tissue in the crossfire.
