IUD may carry higher risk for breast cancer in certain women

Finally!  I am fully convinced that the Mirena IUD I had for total of 9 years had a lot to do with my situation.  A very good oncologist also mentioned that she is seeing a large number of women presenting with BC after use of the Mirena medicated IUD.  I had no idea that the medication could pass into the blood stream.  In fact, I was told that it could not.  I wanted to get off of birth control pills at the time.  For years I was given the synthetic progesterone birth control pills.  Another thing this onc told me is that in the big women's health study from about 5 years ago where HRT was linked to a higher rate of BC, it was the synthetic progesterone, not the estrogen, in the HRT that was causing the problem.  

Now after reading this article, I'm nervous about endometrial cancer.  I know it said that the rate is not higher, but my grandmother had it, plus I've had the Mirena.
