LIPG and breast cancer: We found total cholesterol to increase risk of breast cancer at high levels of LIPG, but to decrease risk at low levels (OR (95% CI) for high levels of total cholesterol among women with high LIPG levels was 8.61 (95% CI 2.38–36.08) versus 0.15, (0.02–0.74) among women with low levels of LIPG (unpublished data)28.
