TUESDAY, Dec. 26 (HealthDay News) -- The recent news that a precipitous decline in the incidence of breast cancer in the United States might be due to women turning away from hormone replacement therapy has some experts worried that the link between the two might have been overstated.

"This is exciting news about the incidence going down, but I think it's very confusing as to whether or not it's related to hormone use," said Dr. William Rayburn, an associate professor of obstetrics and gynecology at Texas A&M Health Science Center College of Medicine. "This has simply muddied the water more."

Similarly, the International Menopause Society (IMS) called on experts and the public "to be very cautious when interpreting the new data on trends in breast cancer incidence in the United States" and said that hormone therapy "has a very minor potential for harm, but may carry substantial benefits."

At the same time, experts continued to urge caution when considering the use of hormone therapy.

"The only reason a woman should take hormone replacement therapy today is to alleviate the symptoms of menopause," added Dr. Jay Brooks, chairman of hematology/oncology at Ochsner Health System in Baton Rouge, La. "It doesn't prevent heart disease. In fact, it increases the risk of heart disease, breast cancer and stroke."

Last week, researchers at the University of Texas M.D. Anderson Cancer Center announced that the incidence of breast cancer in the United States had dropped more than 7 percent, and that this drop came just after millions of women started avoiding hormone replacement therapy (HRT) following the publication of the results of the landmark Women's Health Initiative (WHI) in 2002. That study was halted after researchers found elevated health risks among HRT users, most notably for breast cancer and stroke.
