Western diet raises cancer risk

POST-MENOPAUSAL Chinese women who eat a Western-style diet heavy in meat and sweets face a higher risk of breast cancer than their counterparts who stick to a typical Chinese diet loaded with vegetables and soy, a study says.
The researchers, writing today in the journal Cancer Epidemiology, Biomarkers & Prevention, tracked about 3,000 women in Shanghai, about half of whom were diagnosed with breast cancer.
Post-menopausal women who ate a Western-style diet - beef, pork, shrimp, chicken, sweets, desserts and dairy products - were 60 per cent more likely to develop breast cancer than those eating a diet based on vegetables and soy, the study found.
The study found the increased risk most acute for cancer involving oestrogen-receptor positive tumours. The post-menopausal women with the Western-style diet experienced a 90 per cent increased risk for this type of breast cancer.
One of the researchers, Marilyn Tseng of the Fox Chase Cancer Centre in Philadelphia, said the study detected a much smaller increased breast cancer risk among younger women on a Western-style diet which was not statistically significant.
Tseng noted that breast cancer rates among Asian women traditionally have been low but have been rising in recent years. Some experts have suspected that the adoption of a more Western diet may be at least partly to blame.
