Breaking Medical News: Breast Cancer Epidemic Looms in China

[Guest guest]

I know some people are a little worried about soy products. Some of them are

actually allergic, but others are concerned because of anti-soy propaganda out

there. I'm lucky - not allergic. In any case, whatever, this item may be of

interest. Worth a quick read.

Breast Cancer Epidemic Looms in China

 

China is on the cusp of a breast cancer epidemic, according to the current issue

of the Journal of the National Cancer Institute. Using data from the Chinese

National Family Planning and Reproductive Health Survey, researchers estimated

that the current breast cancer incidence--10 to 60 cases per 100,000 women--will

increase to more than 100 cases per 100,000 by the year 2021.

 

Meanwhile, a Japanese study in the International Journal of Cancer adds more

evidence that traditional soy products help prevent breast cancer. Using a

case-control design, researchers found that women who consumed the most soy

products had roughly a 25% reduction in breast cancer risk. The protective

effect was limited to ER+, PR+, and HER2- tumors.

 

Meat intake has risen dramatically in Asia in recent years, and dairy products

are now heavily promoted. Traditional rice, soy, and other products have become

less fashionable. At the same time, many women are delaying childbirth. These

factors appear to contribute to the increasing cancer risk in Asia.
