My mother now 64 has had trouble with her thyroid all her life. She went through the change of life early but almost died doing so. She would almost bleed to death during her periods. Dr's would not do a hysterectomy on her because they had to do what the insurance required them to do before surgery and that was 3 dnc's.
To make a life long story short, my mother now has ovarian cancer stage 4b. If Dr's would have taken out this mess when they needed to,,, she would not be dieing right now.
Please research everything you can and find out all you can but dont let Dr's wait too long to do something for you. If i was in your shoes, i would want this out of me and demand it to be done, even if you have to pay for it out of your own pocket.
God Bless and hope this has helped you.
