Modern-day external beam radiation therapy

External Beam Radiation Therapy (EBRT) is one of the most common forms of radiation treatment for cancer, where high-energy radiation is directed externally to the tumour. Over 70% of all cancer patients require radiation therapy at some point over the course of their treatment. Over the years, EBRT has evolved with technological advancements.

significant advancements in EBRT. It delivers varying doses to different parts of the malignant tumour based on its shape and size. This is particularly useful for treating tumours located near critical structures, such as the brain, prostate, or the head and neck.

IGRT is another essential component of modern EBRT. This uses advanced imaging techniques before and during treatment to accurately target tumours. It is particularly important as cancerous growths may move due to changes in breathing, digestion, or patient position. This ensures that the radiation is accurately delivered to the cancer, despite slight shifts within the body.
