Two papers recently published from a pilot study looked at environmental and genetic characteristics of women whose sister had breast cancer to identify factors associated with developing breast cancer.

The study found the ageing process was accelerated through DNA changes in women of greater weight and also in those who perceived they had high levels of stress in their lives. In particular, young women who became overweight and remained overweight showed greater changes.

“We know our DNA is affected by our lifestyle including smoking, what we eat, activity and stress levels. These studies highlight the need to begin – and maintain – a healthy lifestyle as early as possible,” says Jean Hailes dietitian Cate Lombard.
