Capturing Food Intake in Patients Undergoing Radiation Therapy for Cancer

The purpose of this study is to determine the feasibility of capturing daily dietary intake of patients undergoing radiation therapy using a mobile food record. This is a prospective single group, non-randomized, feasibility study. 20 participants will be identified during routine clinical care visits with the study PI or co-investigators. Consent will be obtained in person during a clinic visit or using the e-consent process described in section 21.1. They will be asked to use the myCircadian Clock (mCC) app to document their dietary intake for the duration of their radiation treatment. No follow up data will be collected.
