Eligibility: Identical and fraternal female twins who previously participated in the Australian Twins and Sisters Breast Density Study (2005-2007).
Breast cancer is the most common form of cancer in Australian Women. Each year, almost 17,000 women are newly diagnosed, and nearly 3,000 women die from breast cancer. Epidemiological studies have identified a number of factors that can be used to predict which women are more likely to develop breast cancer. However, these risk factors show only a weak association with breast cancer. Since your participation in the last phase of the Australian Twins and Sisters Breast Density Study, we have discovered ground-breaking ways to measure a mammogram to improve risk prediction for breast cancer. Although such newly discovered measures cannot be used alone to predict breast cancer, they provide a substantial improvement to risk prediction in populations.
Participation in this phase involves two parts:
Participation in both parts of this study is completely voluntary, so you can choose to complete one or both components.
Identical and fraternal female twins who previously participated in the Australian Twins and Sisters Breast Density Study (2005-2007) and who have had at least one mammogram in the last 10 years.
