Radiation Therapy (RT) is a common treatment after breast cancer surgery. The high-tech environment and unfamiliar nature of RT can affect the patient’s experience of the treatment. Misconceptions or a lack of knowledge about RT processes can increase levels of anxiety and enhance feelings of being unprepared at the beginning of treatment. Moreover, the waiting time can be long and experienced as meaningless or even life threatening. For successful radiotherapy, the person often needs to be immobilized. A calm, well informed patient might enhance quality of treatment, both from patient and provider perspective. Waiting times can become meaningful instead of meaningless if used wisely for information and preparation for patients and loved ones.
