This project aims to understand better the roles of childhood, adolescence and epigenetics in the risk of breast cancer. Epigenetics refers to changes in the way genes operate due to environmental changes. Studying twin pairs in which one or both have had breast cancer allows a powerful way to study epigenetic and other risk factors for breast cancer.
Participation involves a questionnaire about your medical history and risk factors for breast cancer and a questionnaire about your family history. These questionnaires can be completed online or through a telephone interview and will take about an hour of your time.
You will also be asked to provide a blood sample by attending a participating pathology center local to you.
Twins where one or both have had breast cancer are eligible to participate.
Currently on hold.
