"We know there is a correlation between breast density and breast cancer," Tejal Patel, M.D., breast medical oncologist with Houston Methodist Cancer Center said. "A decrease in density of one percent can potentially translate into a nearly two percent reduced risk of developing breast cancer."
Previous research has shown that olive oil provides many health benefits including lowering the risk for heart disease, high blood pressure and possibly stroke.
Houston Methodist will enroll 100 patients -- 50 premenopausal and 50 postmenopausal women. Each patient will take one 25 mg hydroxytyrosol capsule for 12 months and undergo checkups every three months. There is no placebo control.
In addition to looking at whether hydroxytyrosol has an impact on breast density, researchers will also note possible side effects of the chemical.
