Is radiotherapy safe?
Radiotherapy is a highly controlled and safe treatment delivered by a specialist team including Clinical Oncologists (doctors), Radiation Oncology Medical Physicists and Therapeutic Radiographers. Robust national and international standards must be applied in the delivery of treatment which is closely monitored and regulated. This, as well as the strict and numerous quality assurance processes at all steps of the planning and treatment phases, ensure that radiotherapy is a very safe treatment option To ensure errors are a rare occurrence, equipment is frequently calibrated (adjusted) to confirm correct functioning and both manual and computerised checks are undertaken by several team members before every treatment. Radiation oncology is a discipline in medicine that is renowned for its ongoing world-class education and training programs. All these measures contribute to the quality and safety of treatment delivery. If you have any particular concerns in this regard, you should mention these to the radiation oncology team so they can allay your fears.
