National radiotherapy consent forms

​As with all medical and surgical procedures it is a requirement to take consent for radiotherapy.

There is a unique complexity to the consent process for radiotherapy as there are significant acute risks associated with treatment and late toxicities may present years after treatment. It is therefore generally accepted that the best ethical and legal practice is to ensure valid written, signed consent is sought prior to starting radiotherapy treatment.

  • The taking of written consent should follow a full discussion with the patient of the intended benefits and risks of treatment. 
  • Valid consent is fundamental to respect a patient’s autonomy and is also a legal requirement. 
  • Signing a consent form is not a substitute for a meaningful dialogue and discussion about treatment with the patient.
