Every woman worries about breast cancer, causes, prevention and when it comes to using hormonal treatments, women wonder if there is a link. In the March 2011 issue of Contraception there was a study looking at whether the low leaking of blood levels of progesterone would expose a woman to increased risk of breast cancer, and the answer was no. The study was performed by the makers of the levonorgesterel containing IUD and it was a population based, case control study and there was no increased risk in these users.studied over 5000 European women with breast cancer and over 20,000 European women matched as their controls.
