If you are assigned to the yoga group, during each week of radiation therapy, you will also complete a questionnaire asking your feelings about the Hatha Yoga sessions. You will be asked to list what you liked or disliked, what you found most and least useful, and how you would rate the instructor. You will also be asked about how often you practice outside of class and if you think you are benefitting from the Hatha Yoga program. It should take about 5 minutes to answer this questionnaire. Your answers to the questions will not be shared with your caregiver.
