RondaH,
Here are two links with some information. The first
http://www.breastcancer.org/research...cs_091902.html concludes, "Genes you inherit from your parents probably have a bigger influence on the density of breast tissue, as determined by mammography, than any other single factor."
The second
http://cebp.aacrjournals.org/cgi/con...stract/9/2/151 is to an abstract of a fascinating article (which can be linked from the abstract) titled, "Association of Diet and Mammographic Breast Density in the Minnesota Breast Cancer Family Cohort." The study concluded, "There was a suggestive positive trend between breast density and daily alcohol consumption in both premenopausal and postmenopausal women. After adjustment for other sources of alcohol, only wine intake among postmenopausal women was significant such that white wine showed a positive association and red wine an inverse association with percent breast density. There was no association with other examined dietary factors."
Kate,
I recall reading a quote from a radiologist that reading the mammograms of dense breasted women was like "peering through a snowstorm." It did not give me comfort.
Hopeful
