Had Mirena coils for 10 years before having it removed 2 years ago as I was 52 and was told I didn't need it any more. Had always had acne while it was in place and that didn't clear up after having it removed. A few months ago, by chance, a 7cm tumor was found in my pelvis, which defied diagnosis by ultrasound, MRI and CT scans. My CA125 ovarian tumor markers were over double the normal rate. Gynae Oncologist told me I must have Total Abdominal Hysterectomy, Bilateral Salpingo-Oophorectomy and Infracolic Omentectomy. Had the op 3 weeks ago and am now recovering. Finally had histology report back last week and luckily it was a benign Fibrothecoma! Strangely, my acne disappeared with it and I reckon the tumor had been there for some time. Is this a coincidence? I can't convince myself it is and would urge users to be very vigilant.
