Variations in percent mammographic density (PMD) reflect variations in the amounts of
collagen and number of epithelial and non-epithelial cells in the breast. Extensive PMD is …

Epidemiologic studies have contributed importantly to current knowledge of environmental
and genetic risk factors for breast cancer. Worldwide, breast cancer is an important cause of …

Purpose Mammographic breast density is an established risk marker for breast cancer and
is visually assessed by radiologists in routine mammogram image reading, using four …

OBJECTIVE. Breast density is increasingly recognized as an independent risk factor for the
development of breast cancer, because it has been shown to be associated with a four-to …

Breast density, as assessed by mammography, reflects breast tissue composition. Breast
epithelium and stroma attenuate x-rays more than fat and thus appear light on …

Background The long time from exposure to potentially harmful chemicals until breast
cancer occurrence poses challenges for designing etiologic studies and for implementing …

Background: About half of the United States has legislation requiring radiology facilities to
disclose mammographic breast density information to women, often with language …

In this review, we examine the evidence for mammographic density as an independent risk
factor for breast cancer, describe the risk prediction models that have incorporated density …

There is now extensive evidence that mammographic density is an independent risk factor
for breast cancer that is associated with large relative and attributable risks for the disease …

Background Soy and red clover isoflavones are controversial due to purported estrogenic
activity and possible effects on breast cancer. We conducted a systematic review of soy and …
