Who prescribes the radiotherapy treatment plan?

• A. Radiation Therapist
• B. Medical Physicist
• C. Radiation Oncologist
• D. Nurse

Answer: (C)

In radiotherapy, the person who determines and authorizes the dose and schedule is the Radiation Oncologist, a physician who specializes in treating cancer with radiation. This clinician reviews the patient’s cancer type, stage, and overall health, then decides the total dose, how it is fractionated (divided into sessions), and the exact treatment targets. The plan is then carried out by the rest of the team, with the Medical Physicist handling precise dose calculations and quality checks, and the Radiation Therapist delivering each treatment session according to that plan. Nurses support patient care but do not set the treatment prescription. So, the Radiation Oncologist is the one who prescribes the radiotherapy treatment plan.
