Postmenopausal breast cancer risk: Intensity and timing of exercise

Intensity and timing of physical activity in relation to postmenopausal breast cancer risk: the prospective NIH-AARP Diet and Health Study

"A high level of recent, but not historical, physical activity of moderate-to-vigorous intensity is associated with reduced postmenopausal breast cancer risk."

Soy reduces the risk of postmenopausal breast cancer

In this study the urinary excretion of genistein was measured.

Urinary phytoestrogen excretion and postmenopausal breast cancer risk: the multiethnic cohort study

"Our results provide some support to the hypothesis that a diet rich in isoflavones from soy products reduces the risk of postmenopausal breast cancer, particularly in populations with comparatively high excretion of phytoestrogens."

Dietary patterns and breast density

Dietary patterns and breast density in the Minnesota Breast Cancer Family Study

"Overall our results do not provide strong evidence for associations of dietary patterns with breast density. Suggestive inverse associations for the fruit-vegetable-cereal and salad-sauce-pasta/grain dietary patterns among smokers are consistent with previous reports and leave open the possibility that some dietary patterns influence breast density in population subsets."
