Studying Wines’ Effects on Cancer
Forum reviewers considered the results interesting and that they contribute to the understanding of the relation of wine to hormonal levels. On the other hand, they were concerned about methodological problems, including a lack of baseline data and variations in the timing during the menstrual period of blood sampling (which could affect estrogen levels). Also, no significant effect of the interventions was seen on blood levels of estradiol.
Further, the forum thought it should be pointed out that data are inconsistent on the relation of red wine consumption to the risk of breast cancer; many studies do not show beverage-specific effects on risk. More research will be needed to determine if the polyphenols in red wine can play a role in lowering the risk of breast cancer.
