Breast CANcer Risk Assessment in Younger Women: BCAN-RAY

The overarching aim of the proposed research is to develop a comprehensive breast cancer risk assessment strategy for women aged 30-39 years. There are three main objectives to the study. Objective 1 - Mammographic Density and Risk To define the magnitude of BC risk associated with MD in women aged 30-39 and facilitate its incorporation into risk prediction models. Objective 2 - Psychological impact To examine the feasibility of a strategy to offer breast cancer risk-assessment to diverse ethnic and socioeconomic populations of women in their 30s, assessing: * Potential benefits and harms * Impact on health inequalities * Acceptability Objective 3 - DNA Methylation substudy To explore the potential of DNA Methylation (DNAme) signatures from self-obtained cervical samples to further refine risk prediction algorithms
