WASHINGTON (WUSA) -- Recent studies have highlighted the danger of too much alcohol when it comes to risk factors for breast cancer, but there may be one type of drink with a different effect.

Researchers at Cedars Sinai Medical Center looked at 36 younger women who drank eight ounces of cabernet sauvignon or chardonnay daily for almost a month, and then switched to the other other type of wine for a month. They saw a difference in the women who drank red. 

Dr. Chrisandra Shufelt, who authored the study and works at Cedars-Sinai Medical Center, said, "In red wine the hormone levels, the estrogen levels decreased while the testosterone levels increased...and that may actually be a change for risk factors for breast cancer risk."

Dr. Shufelt says that's encouraging because the change in hormone patterns suggests red wine may prevent the growth of cancer cells.

These new findings challenge much of the current research on alcohol and breast cancer. One study late last year that found women had a 15 percent increased risk of breast cancer if they drank three to six drinks a week.

The antioxidants in red wine have also been touted as having a protective effect for the heart, but there's no question: heavy drinking of ANY type of alcohol cancels out any health benefits.
