Middle aged women who do 30 minutes of exercise a day cut chance of breast cancer

[Northerner]

Middle aged women who regularly do aerobics, Zumba or step classes are protecting themselves against breast cancer, research shows.

Doing half an hour’s vigorous activity a day – including squash or a spinning class – reduces the risk by a fifth.

Scientists also found that obese women are over 50 per cent more likely to develop the illness than those who are slim.
