Diabetes Care for Breast Cancer Patients

The goal of this study is to find a new way to make diabetes care better for patients with breast cancer and diabetes who are currently receiving cancer treatment. We will have two groups, the researchers will decide who is in which group. One group will be working with a nurse who is trained in diabetes care while the other does not. This will allow the investigators to see if having a trained nurse as part of the care team can help improve the care the patients receive.
