Women who take a common form of HRT are nearly three times as likely to get breast cancer, a major study has found.
Scientists at the Institute of Cancer Research in London say the risks of taking the pills have been underestimated for years – and are actually 60 per cent higher than thought.
The findings, based on a study of 39,000 British women tracked as they went through the menopause, will re-ignite a 20-year-old debate about the benefits and risks of taking HRT.
