Hormone replacement therapy (HRT) was back in the spotlight last night after an Oxford study found it raised the risk of breast cancer by a third.
Researchers said women aged 50 to 69 were 32% more likely to get the disease if they had taken the most common form of the hormone replacement therapy for at least five years.
The danger was twice as high for patients on the treatment for a decade.
The Oxford team said however that the overall risk was still small – and doctors said the benefits often outweighed the risks. Based on 58 global studies, the research suggested that HRT causes around one in 20 cases of breast cancer – nearly 3,000 a year in Britain.

It is the 'holy grail' for scientists seeking to save thousands of people the misery of a trip to the dentist for a filling.
Now researchers have invented a material which could help people regrow their own tooth enamel naturally.
For more than a decade scientists have been trying to replace fillings by making tooth enamel regrow, by providing it with extra calcium phosphate. The problem was that the new enamel did not have the right 'fish-scale' structure and consequently was too soft.
But now scientists have used extra tiny clusters of calcium phosphate which organise into hard enamel within hours.
Taking up exercise in your 70s or 80s can still have major benefits - even after a lifetime on the couch.
Experts at the University of Birmingham found elderly people who had never done structured exercise before still benefited from sessions in the gym.
And they had the same ability to build their muscles as highly-trained master athletes of the same age.
Researchers said the findings showed it is never too late to get fit - and even walking up the stairs or pottering around the garden can have benefits.
