The Sister Study

Proudly serving women who are helping us find the causes of breast cancer.

The Sister Study team

Every year a dedicated contract staff sends out thousands of annual update requests, questionnaires, newsletters, letters and cards; and responds to phone calls and e-mails. Staying in touch with sisters for the duration of the study, answering questions, and keeping track of updates is no small task.
