Hi All,
I am not sure where should I post this. I am hoping you can give me some advices.
I was diagnosised as complex endometrium hyperplasia with atypia in 2002 and was put on tons of progestron in the past few years to prevent endometrium cancer. During the past few years, I went through 5 fresh IVFs and the last one result my DD. I can't believe how lucky I am to have her. Three months after delivery, a biopcy shows the endometrium hyperplasia came back , this time without atypia. Paps mear also have mild changes. I was refer to an oncologist right away. I told him that I still have 4 embryos left on ice so I still have chance to get pregnant. He suggested a D&C to make sure the biopcy didn't miss out any atypia cells. If there is no atypia, he suggested put a IUD in me to give me progestrone directly into my uterus instead of takeing high dose progestrone in the coming year. He doesn't suggest a hysterectomy at this point. However, I am really on the fence if I should just go ahead with hysterectomy. I had a C cection birth so if I want to put those embryos back, I have to wait for another year. During this year, I have to keep an eye on my uterus and cervics. That means many Dr, appointments, biopcys......I am already 40 years old, and the last 8 years , ivf is the only thing in my life. I am so tired of worring all the time. I am really not sure if I should take the risk for another year. On the other hand, if I do a hysterectomy now, I feel bad for my left embryos. It feels like to left a baby behind. I will always wondering what if I give them a chance for the rest of my life. I know it is a big decision to make. Please give me some insight, any advice is welcome.
Thanks.
