Why is the Level of Estrol Higher in Western Women than Asian Women?

Questions to Doctor Robert N Hoover, MD, PhD, Director of the Epidemiology and Biostatistics Program in the Intramural Research Program of the National Cancer Institute at the NIH’s Director’s Wednesday afternoon lecture series – May 16, 2007 – “Hormones and Breast Cancer”

Question: Is the higher level of estrol levels in western women different (from Asian women) because of the diet, or enzymes, genetics or some combination?

Answer: Nobody knows the answer because nobody has been investigating them in the human population. There has been some speculation that it may not be genetically driven but that it may be environmentally driven. If it is, it would be a big help because it might give us a clue as to what really is the cause for (estrol) rates being so much lower in China than they are here (in the US).
