In the largest and most comprehensive study of its kind, researchers have provided further evidence that a hormone responsible for regulating breast development acts as a risk factor for breast cancer in post-menopausal women.
By studying a large population, the researchers could identify groups of women for whom this hormone – called prolactin – is most strongly associated with breast cancer risk. Their findings will help advance the understanding of what causes breast cancer and could influence future approaches to risk prediction and prevention.
Scientists based at The Institute of Cancer Research, London, were involved in the international study, which was carried out by researchers across the United Kingdom, the United States, Canada and Australia.
