Why the data was released

Objective for processing

A national population based study of treatment effect and endocrine, genetic and cellular risk factors for contralateral primary cancer in women in Britain.  Short title; British Breast Cancer study - (NCRN cohort)One of the aims of the genetic component of this study is the identification of low penetrate breast cancer susceptibility alleles.  TO this end, several (lab-based) studies are already underway.  Epidemiological studies, published data from association studies and our own, unpublished, results suggest that some alleles confer risks for a broad spectrum of cancers.  We have now a large population-based cohort of about 25,000 breast cancer cases, both bilateral and unilateral cases.  This cohort contains the largest collection of bilateral breast cancer cases in the world.  It is thus ideal for carrying out association studies to identify breast cancer susceptibility genes and assess their value in risk prediction.  For this, it is vital to ascertain cancer diagnoses and status.
