Could Statins Cut Breast Cancer Risk?
(HealthDay News) — Women with hyperlipidemia have an increased risk of developing breast cancer, according to a study presented at the European Society of Cardiology's Frontiers in CardioVascular Biology 2014, held July 4–6 in Barcelona, Spain.
Rahul Potluri, MBBS, from Aston University in Birmingham, U.K., and colleagues examined the risk of breast cancer among patients with and without hyperlipidemia in the Algorithm for Comorbidities, Associations, Length of stay and Mortality study population. Of the 664,159 women, 22,938 patients (3.5%) had hyperlipidemia and 9,312 had breast cancer.
The researchers found that 2.3% of the patients with hyperlipidemia had breast cancer, compared with 1.4% of those without hyperlipidemia. The presence of hyperlipidemia was associated with a 1.64-fold increase in the risk of having breast cancer, after accounting for the time from first presentation to development of breast cancer.
"Our preliminary study suggests that women with high cholesterol in their blood may be at greater risk of getting breast cancer," Potluri said in a statement. "It raises the possibility of preventing breast cancer with statins, which lower cholesterol, but as this is a primitive study, significant time and research is needed before this idea can be tested."
