Breast Cancer
Participants are asked to report all cancer diagnoses (excluding non-melanoma skin cancer) at baseline and periodic follow-ups. They can also contact the Sister Study Helpdesk via telephone or email to report diagnosis. Women are asked for permission to contact their health care providers for the retrieval of medical records and pathology reports to complement self-reported data. Summary of baseline and incident cancer cases and validation results, data collection, and additional details on cancer characteristics can be found in the links below.
