Speaker: Professor Valerie Beral


Director, Cancer Epidemiology Unit, University of Oxford

Born in Australia, Professor Beral studied medicine at Sydney University, graduating in 1969 with bachelor degrees in both medicine and surgery, with first class honours. After a few years of clinical work in Australia and New Guinea she moved to the UK. At the Hammersmith Hospital, Dr Beral worked under Charles Fletcher who recognised that she was suited to epidemiology and so propelled her towards the London School of Hygiene & Tropical Medicine, where she worked for almost 20 years in the Department of Epidemiology. She also became a member of the Royal College of Physicians.

In 1988 she moved to direct the Cancer Research UK Cancer Epidemiology Unit in Oxford. Major research includes the role of reproductive, hormonal and infectious agents in cancer. She is Principal Investigator for the Million Women Study on the effect of women's lifestyle on health, with particular focus on the effects of hormone replacement therapy. Since 1991 this has led the international collaborative studies of breast, ovarian and endometrial cancer. Dame Valerie has served on various international committees for the World Health Organization and the United States National Academy of Sciences. She also chairs the UK Department of Health's Advisory Committee on Breast Cancer Screening.

Her honours include being awarded Dame of the British Empire (DBE) and Companion of Australia (AC) for her contributions to science. In addition, Professor Beral was awarded Fellowship of the Royal Society (FRS), for scientific contributions to epidemiology.


Launched in 1997, the Million Women Study has since recruited 1.3 million UK women over the age of 50, through NHS breast screening centres. One in four UK women in the target age group have participated in the study, making it the largest of its kind in the world. Confirming the relationship between HRT and the risk of breast, endometrial, and ovarian cancer, the Million Women Study has had a dramatic effect on HRT prescription patterns and prescription guidelines, leading to a reduction in breast cancer rates.

Since the publication of the Women’s Health Initiative trial and the Million Women Study, sales of HRT have halved in the US, UK and Europe. Consistent with the drop in HRT use, the incidence of breast cancer has also markedly decreased in women over the age of 50 in the US, UK and Europe.
