Studies on the changes in plasma lipids and lipoproteins in patients with benign and malignant breast cancer

Abstract

Experimental studies and epidemiological data suggest that, high fat diet increases the risk of developing breast cancer, both in animal and in human population. Cases of postmenopausal, untreated women with malignant and benign breast tumors, were compared for their age, body weight, plasma lipid fractions and lipoproteins. There was a significant increase in body weight, total plasma lipids, total cholesterol, LDL--cholesterol, VLDL--cholesterol, phospholipids, triacylglycerols, free fatty acids in malignant breast cancer patients. HDL--cholesterol had been significantly decreased in benign and malignant patients when compared with the control subjects.
