Fat and cancer: does fat of any kind cause cancer?

Low-Fat Dietary Pattern and Cancer Incidence in the Women’s Health Initiative Dietary Modification Randomized Controlled Trial
Journal of the National Cancer Institute (2007)
Prentice RL, Division of Public Health Sciences, Fred Hutchinson Cancer Research Center, et al.
Conclusions: “A low-fat dietary pattern may reduce the incidence of ovarian cancer among postmenopausal women.”

Low-Fat Dietary Pattern and Risk of Invasive Breast Cancer: The Women’s Health Initiative Randomized Controlled Dietary Modification Trial
Journal of the American Medical Association (2006)
Prentice RL, Division of Public Health Sciences, Fred Hutchinson Cancer Research Center, et al.
Conclusions: “Among postmenopausal women, a low-fat dietary pattern did not result in a statistically significant reduction in invasive breast cancer risk over an 8.1-year average follow-up period. However, the nonsignificant trends observed suggesting reduced risk associated with a low-fat dietary pattern indicate that longer, planned, nonintervention follow-up may yield a more definitive comparison.”
