Black cancer patients tend to have worse outcomes than White cancer patients. Some of this disparity may be due to comorbidities. The purpose of this study is to improve management of co-morbidities among cancer patients in order to improve cancer outcomes and improve health equity.

Comorbidities such as diabetes and hypertension can complicate cancer treatment or can make it difficult to reach optimal health after treatment. This study will offer additional support and tools to manage cancer patient's health needs. First, the study will use a mobile health application, managed by a company called Welldoc, to monitor patient progress in real time and to provide ongoing guidance. Second, the study will connect patients with a Community Health Worker who will speak with them weekly to discuss self-care information, including medical scheduling or appointment needs, and assist with daily self-monitoring of blood pressure and/or blood glucose monitoring. Lastly, an oncology nurse will monitor reported health and triage any medical needs and whether additional medical care is needed.
