Hi YvetteM
I had a Mirena in. I was 47 years old, peri-menopausal and diagnosed with Triple Positive BC. I have since completed chemo/targeted therapy, had a double mastectomy and now on hormonal therapy. I had no familial link to breast cancer and my only risk factors were being a low-level drinker of alcohol and having my first child at 31 years old.
I loved having the Mirena (which I got after I finished having kids and had replaced a couple of times). Prior to having kids, I was on the progesterone only contraceptive pill, so similar hormonal impact perhaps???
Because my cancer was highly ER/PR+ (as well as HER2+), I was recommended to remove the Mirena after I was diagnosed as it was likely contributing to its growth. But I couldn't say that there was any link between the Mirena and the cause of my cancer.
Thanks that is very interesting. I was told that the Mirena's effect is localised to the uterus, but recent studies show detection of hormone impacts in breasts. Perhaps the impact is the same as the oral contraceptive pill...perhaps not.
I hope your recovery continues to go well and any remaining treatments you may need- or even better if you are in remission!
