Fatty fish and fish omega-3 fatty acid intakes decrease the breast cancer risk

Fatty fish and fish omega-3 fatty acid intakes decrease the breast cancer risk: a case-control study

CONCLUSION: These results suggest that high consumption of fatty fish is associated with a reduced risk for breast cancer, and that the intake of omega-3 fatty acids from fish is inversely associated with postmenopausal breast cancer risk.

Obesity, mammography and advanced breast cancer risk

Obesity, mammography use and accuracy, and advanced breast cancer risk
J Natl Cancer Inst. 2008 Dec 3;100(23):1724-33. Epub 2008 Nov 25.

CONCLUSIONS: Patterns of mammography use and mammography accuracy are not the primary reasons for higher rates of advanced breast cancer among overweight and obese postmenopausal women not using HT; thus, biologic differences in breast tumor development and/or progression may be important.

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."
