Obese breast cancer survivors have a higher risk of cancer recurrence, but only 34% participate in the recommended level of physical activity. A new app called the Methodist Hospital Cancer Health Application (MOCHA), developed by the Methodist Hospital Cancer Center in Houston, Texas, may help breast cancer survivors meet weight loss goals through daily self-reporting of activity and nutrition, as well as group feedback and engagement with a clinical dietician. A team from Methodist Hospital discussed the app at the 2017 San Antonio Breast Cancer Symposium (SABCS 2017).

In a trial of the app, a total of 33 breast cancer survivors who had a body mass index (BMI) higher than 25 and were at least 6 months post active treatment were enrolled in the study. Over 4 weeks patients used the app to track wellness, including mood, sleep, or pain, as well as diet, and exercise. Personalized goals for each user were set by a registered dietician, who also sent regular push notifications to keep users on track.
