Cholesterol Forges Link Between Obesity and Breast Cancer
Menée in vitro, in vivo et à l'aide de données portant sur des échantillons tumoraux prélevés sur des patientes atteintes d'un cancer du sein, cette étude met en évidence des mécanismes permettant de rendre compte du lien entre hypercholestérolémie et cancer du sein
Cholesterol, the artery-clogging molecule that contributes to cardiovascular disease, has another nasty trick up its sleeve. When metabolized by the body, it turns into a potent estrogenlike molecule that spurs the growth of breast cancer in mice, and perhaps in some women. That's the conclusion of a pair of surprising studies that shed new light on the link between obesity and cancer.
