Study links soy consumption to breast cancer survival quoting : UPI

In the past, there has been some controversy over the consumption of soy because of concern its estrogen-like properties could increase the risk of the most common form of breast cancer, hormone receptor-positive breast cancer. "For women with hormone receptor-negative breast cancer, soy food products may potentially have a protective effect. March 6 (UPI) -- New research from Tufts University debunks the myth that soy consumption increases estrogen levels and could lead to breast cancer in women. "Because of this disparity, it remains unknown whether isoflavone consumption should be encouraged or avoided for breast cancer patients," he said. Women who did not receive endocrine therapy as a treatment for their breast cancer had a weaker, but still statistically significant, association."




"We now have evidence that soy foods not only prevent breast Cancer but also benefit women who have breast cancer," Kucuk concludes. The findings are based on a study of 6,235 women with breast cancer in the United States and Canada, all of whom were enrolled in the Breast Cancer Family Registry. And for some breast cancer survivors, soy seems beneficial. Women with breast cancer sometimes get confusing messages about soy-based foods, including soy milk, edamame and tofu. On one hand, studies have suggested that the estrogen-like compounds in soy — called isoflavones — may inhibit the development or recurrence of breast cancer.

Is soy OK for breast cancer patients?

They were enrolled in an international breast cancer registry and their diet was assessed over an average of 9 1/2 years. Higher estrogen levels have been linked to the growth and spread of breast cancer in the most common form of the disease. "The evidence has been found in two directions so that's why it's controversial."Marianne Lu, 32, is battling aggressive breast cancer. The study may help clear up confusion over whether soy products such as tofu, soy milk, edamame, tempeh and miso – foods rich in estrogen-like chemicals – are OK to consume if you have breast cancer. "I think it's safe to say soy doesn't have harmful effects on breast cancer," she concluded.
