Evaluation of serum lipids and high-density lipoprotein subfractions (HDL2, HDL3) in postmenopausal patients with breast cancer.

Breast cancer patients are known to be at increased risk for developing other chronic diseases including cardiovascular disease. Studies by different investigators have shown a correlation between increased dietary fat or hypercholesterolemia and the occurrence of breast cancer. Since previous studies on lipoprotein subfractions in this type of cancer have been inconsistent, we evaluated the lipids and lipoprotein subfraction levels in postmenopausal patients with breast cancer in an attempt to identify the risk for the development of cardiovascular disease.
