Breast Cancer: New Study on Soy

Researchers have some interesting news for breast cancer survivors who avoid eating soy due to concerns that it will affect medicine they take and trigger new cancer growth.
After analyzing data from more than 18,000 women who had been diagnosed with breast cancer nine years prior, they found that eating soy did not increase their risk of getting breast cancer again or dying from the disease.
In fact, researchers noted a trend that eating soy reduced mortality and reoccurrence. However, more study is needed to determine the significance of this finding, the scientists said.
Women who consumed the highest amount of soy – 23 milligrams or about one glass of soy milk daily – had a 9 percent reduced risk of dying and a 15 percent lower risk of getting breast cancer again, according to the study.
“Our results indicate it may be beneficial for women to include soy food as part of a healthy diet, even if they have had breast cancer,” said lead researcher Xiao Ou Shu, M.D., Ph.D., professor of medicine at Vanderbilt Epidemiology Center, Vanderbilt University Medical Center, in a news release. “This can’t be directly generalized to soy supplements, however, as supplements may differ from soy foods in both the type and amount of isoflavones.”
The results of the study were presented this month at the annual meeting for the American Association for Cancer Research.
Researchers involved in the study said the results did not reach what they consider “statistical significance,” suggesting the finding could be chance.
