Overseas health insurance customers should discuss the best ways of lowering their risk of developing breast cancer.
According to recent figures published by the World Cancer Research Fund (WCRF), in the UK alone, around 20,000 of the 47,600 new cases of breast cancer in 2008 could have been prevented through healthier lifestyle choices.
Maintaining a healthy weight, lowering alcohol consumption and keeping physically active are the top three ways of reducing the risks.
Dr Rachel Thompson, deputy head of science at the WCRF, commented: "What these figures show is that people can do a lot to reduce their chances of developing cancer.
"Overall, we estimate about a third of the most common cancers could be prevented through a healthy diet, being physically active and maintaining a healthy weight."
According to the charity, women should keep their alcohol intake to one drink a day, and should aim for at least 30 minutes of physical activity a day.
