For lipids measured using clinical chemistry, breast cancer patients had higher mean concentrations of total cholesterol (208.06 ± 31.40 in breast cancer patients compared to control women 194.18 ± 28.31; p = 0.002), Apo B100 101 (85–118 in breast cancer patients compared to 91 (78–104) in control women; p = 0.008), and triglycerides (86.73 (67.69–120.16) in breast cancer patients compared to 76.55 in control women (56.83–98.74); p = 0.004). This evidence concerns the gene APOB and breast cancer.
