Purpose To explore whether the timing of patient education sessions influences levels of satisfaction in women treated for breast cancer. Methods Two groups of participants, 350 women total, were surveyed retrospectively via a postal questionnaire. Participants from group 1 received a patient education session following their first radiation therapy treatment. Group 2 received a patient education session on the same day as their computed tomography (CT) simulation appointment. Data were analyzed using descriptive and inferential statistics. Results No significant difference in the levels of satisfaction was found between the 2 groups. Satisfaction levels were high in both groups across all measures; however, satisfaction levels were lowest when participants were asked how satisfied they were with the information provided about support services. Discussion The timing of patient education did not significantly influence the level of patient satisfaction among the study participants. When given a choice, the majority of patients stated they preferred to receive a patient education session on the same day as their CT simulation vs other time points. Conclusion Patient preference for the timing of education sessions should be accommodated whenever possible; however, it also is reasonable to consider the operation requirements of the department when scheduling education sessio
