A major new study claims women who take the most commonly used form of hormone replacement therapy (HRT) are nearly three times more likely to develop breast cancer than those who do not.
The Institute of Cancer Research looked at six years of data for 39,000 menopausal women, of whom 775 had developed the illness. It found those taking combined oestrogen-progestogen HRT – the most popular form – were 2.74 times more likely to develop breast cancer than those not using any HRT at all.
