San Diego: Eating healthy food and taking regular exerice, cuts the risk of dying by half in breast cancer victims, say scientists at the University of California.

Walking for thirty minutes and eating five portions of vegetables and fruit daily offers protection even in obese women.

The studyis the first to look at the combined effects of diet and exercise directly on the survival rates of cancer victims and studied 1,490 women with an average age of 50.

All the women, who had undergone primary therapy for early-stage breast cancer took part in the Women’s Healthy Eating and Living study.

It was concluded that women who were both physically active and had a healthy diet were much more likely to survive for between five and 11 years longer than the others. Only around 7 per cent of the ‘ healthyliving’ women died within 11 years – about half that seen for the others taking part in the study.

The findings are published in the latest issue of the Journal of Clinical Oncology.
