The risk of womb cancer can be reduced by exercise, diet and possibly drinking coffee, according to research. Almost half of cases of womb cancer in the U.K., about 3,700 a year, can be prevented through keeping slim and active. Researchers at Imperial College, London, say women can reduce their risk with at least 30 minutes of daily exercise and keeping a healthy weight and The World Cancer Research Fund report also found that coffee could help reduce the risk. But experts say there is not yet enough evidence to recommend drinking coffee to protect against the disease. It is reported that only 56 per cent of women in the U.K. follow recommendations to be physically active for at least 30 minutes a day, five days a week, while only 39 per cent have a healthy weight. Study author Dr Teresa Norat of Imperial College tells the BBC, "If you are physically active and if you don't have excess body weight you can reduce your risk of womb cancer and improve your health in general."
