I have a uterus with large fibroids which cause horrific periods every 25 to 27 day cycles. Very regular on my cycles. Never miss a period. I have annual ultrasounds, and the one in June, 2016 showed an enlarged uterus, two large fibroids, but the ovaries were normal. I have been experiencing constant lower back pain and lower abdominal pain for years now. This last year, it got worse. The last month it was constant, and I lived on ibuprofen which stopped helping and a heating pad. I got my period a couple of days ago (26 day cycle) and this time the blood loss was horrendous and I had snap abdominal pain. Went to the ER. They Did an ultrasound both transvaginal and regular. The findings showed an enlarged uterus with multiple fibroids and a thick lining. However, it also showed my left ovary enlarged with a complex cyst measuring 3.4x1.7 by 1.6. The right ovary is normal. It also states there is vascular flow seen within bilateral ovaries and no free fluid. I had sharp stabbing pains in my pelvic area while n the ER, low grade fever and slightly elevated white cell blood count. I am 48, almost 49, and scared out of my mind. I was also shown to have anemia, even though iron was high as I take iron supplements for the horrific periods. I am BRACA and Lynch Syndrome negative. Do have Breast cancer and pancreatic cancer on mom's side of family, although no personal history of cancer so far. Seeing my gyno tomorrow, but scared about the cyst. It formed within the past 11 months, as not visible on ultrasound from June 2016. Also, uterine biopsy was negative last year. What are the chances I got overian cancer? I was never pregnant. I never took hormones. I have been battling fibroids since my 30s and had a maymectomy over a scare ago. The fibroids returned with a vengeance, and I am ready to do a hysterectomy, because I have no life quality with the horrific bleeding every 25 days on average, and the constant pelvic and lower back pain that now has been going on for more than a year. But, I was hoping to keep the ovaries, and have a partial hysterectomy. Now, with this complex ovarian cyst, I think I will need full hysterectomy, and I am pat rifled of cancer.
