Radiation therapy for the treatment of cancer includes. To eradicate cancer cells and reduce tumours, radioactive sources are inserted within the patient. This enables your doctor to treat a smaller area with a higher overall dosage of radiation while avoiding radiation exposure to some nearby organs. Internal radiation therapy, also known as brachytherapy, involves putting radioactive material right into or close to the tumour. In contrast to external beam radiation therapy (EBRT), which shoots high-energy x-rays at a tumour from outside the body, it employs a higher total dose of radiation to treat a smaller region.
