Breast cancer is one the most common
malignancies and leading cause of
cancer-related mortality in women. Recent studies suggested that
hypercholesterolemia may be the potential modifiable risk factors for
breast cancer.
Cholesterol was well-known for its strong association with
cardiovascular disease for long. Moreover, solid evidence has been provided by different studies to illustrate the correlation between
lipid and incidence in multiple
cancers. Although the conclusion remains controversial or sometimes contrary, which may be due to the multifactorial nature of the disease and the disparity of ethnic population, it is critical to elucidate the relationship between specific
cholesterol components in certain population and the exact underlying mechanism of the
lipid-associated signaling pathway in
breast cancer. The implications of dysregulated
lipoproteins as therapeutic targets or options for
breast cancer provide novel strategies for us in combating with this malignant disease, which may be achieved by manipulating
lipid levels with pharmacological compounds.
