Investigation of a Digital Healthy Habits Program for Individuals With Breast Cancer

This mixed methods study will involve obtaining user feedback on the first 4 weeks of the Healthy Habits for Cancer (HCC) Program. Participants will be recruited and asked to try the HCC app for 4 weeks. Short pre and post surveys and in-depth qualitative interviews will be conducted exploring their views on the app, the extent to which they believe the app would have to be further adapted, how they would feel about such an app being embedded in their cancer care and when in their care pathway they would like to be offered it.
