High serum HDL-cholesterol in pre- and post-menopausal women with breast cancer in southern Italy.
Up until now, conflicting results have been reported on the association between serum cholesterol and risk of breast cancer in women. In this study, the serum concentrations of cholesterol, HDL-cholesterol, triglycerides and total lipids in women with breast cancer (BC) have been compared to those of women with benign breast disease (BBD). BC women had higher serum concentration of HDL-cholesterol both in pre- and in post-menopausal age. No difference was observed in the serum concentration of total cholesterol, triglycerides and total lipids. These findings could be explained by an increased estrogen activity which is believed to be involved in the development of breast cancer, and in the modulation of lipid metabolism (lowering LDL-cholesterol and increasing HDL-cholesterol). High serum HDL-cholesterol could be a biochemical index of increased risk of having breast cancer.
