Breast CAncer Stratification (B-CAST): Understanding the determinants of risk and prognosis of molecular breast cancer subtypes

Breast CAncer Stratification (B-CAST): Understanding the determinants of risk and prognosis of molecular breast cancer subtypes

Studies 0
In B-CAST the overall goal is to investigate the determinants of the development of specific breast cancer subtypes, and subsequent prognosis. Models and tools will be developed to allow identification of the individual risk of breast cancer, the subtype of cancer that is most likely to develop and the prognosis of that particular subtype. The specific project objectives are: * To define the influence of risk factors, including reproductive history, lifestyle, mammographic breast density and germline genetic variation, on breast cancer overall and by subtypes characterized by clinical and molecular markers. * To define the influence of risk factors and tumour subtypes on clinical prognosis. * To develop and validate breast cancer risk and prognostication models for breast cancer, overall and by subtypes, informed by knowledge acquired under above objectives * To implement these models into online tools for risk prediction and prognostication; and make them available in multiple countries/languages. * To raise awareness, i.e. promote the development and integration of personalized breast cancer prevention within national public health programmes..
