Radiotherapy is a three-year undergraduate program that focuses on radiotherapy. The scientific field of radiotherapy examines radiotherapy and how it is applied to the treatment of cancer patients. Other names for it include XT and XRT. In order to stop the spread of the disease before or after surgery, radiotherapy, which helps to destroy malignant cells, is a crucial part of cancer treatment. It is a supplemental medication used in conjunction with chemotherapy to stop the spread of illness. Though it is also used to treat some non-cancerous disorders, radiation oncologists and radiotherapy students collaborate closely to treat cancer patients. Students who are passionate about biology and have a firm grasp of physics can pursue a lucrative career in this area of study.
