Research on nutrition and cancer?

Page last modified on: September 29, 2008
Question from Carrie: I've read that there has been an increase of breast cancer in women in Singapore and China as their diets become more urban and westernized. Are researchers getting closer to identifying a nutritional cause or deficit in the diet of women who develop breast cancer?
Answer —Cyndi Thomson, Ph.D., R.D.: Diet is thought to contribute to about 30 percent of all cancers. Although it is a considering factor, it alone is unlikely to be the "cause" of cancer. However, it is clear that the native diets of Singapore appear to be more protective than the westernized diets of the U.S. The take-home message should be to maintain your native diet as much as possible. There are many other factors that can contribute in the culture, not the least of which is reduced physical activity. In addition, Singapore, like most countries, may be experiencing an increase in cases partially because of improved screening and longer life expectancy.
