Cancer experts are to carry out a major study to see if commonly used blood pressure drugs cut the risk of breast cancer spreading.Data from 800 patients has already shown those previously given beta blockers had half the chance of their cancer spreading as women who had not.
So-called secondary cancers have a high death rate.
The Cancer Research UK backed study will look at about 30,000 patients, and will report next year.
If that too shows benefits from the medication, further research in which breast cancer patients would be treated with beta blockers, would follow.
Doctors cannot move straight to this kind of study because they need to have more evidence there is a beneficial effect of taking beta blockers first.
They say there is no evidence so far that anything else explains the benefits seen - but the large study will look into that even further.Read more at BBC
