In this study the research team collected blood samples and information about lifestyle and family medical history from women with breast cancer. They also collected information from women who had not had breast cancer.

The aim of the study was to find out more about the pattern of cancer in the families of women with breast cancer. And to find out what specific factors might be causing this.

Summary of results

The information and blood samples collected in this study have been used to look for genes that increase the risk of breast cancer. The UK researchers have found some genes themselves. They have also contributed samples and information to many international studies which have so far discovered about 70 such genes. Although the study finished recruiting in 2010, work using these samples will continue for many years.
