Breast Cancer
Breast Cancer
When participants report breast cancer diagnoses, women are asked for permission to contact their health care providers for retrieval of medical records and pathology reports to complement self-reported data. In addition, participants are asked to complete a Breast Cancer Follow-Up Form (BCFF). Details on breast cancer data collection and validation, including the positive predictive values (PPVs) for self-reported breast cancer and diagnostic characteristics, and number and type of incident breast cancers can be found in the links below.
