I am sorry to hear of your distress. I also have a dermoid cyst, 8.5 x 6.5. I am 46 and obese, and will by having a hysterectomy on 04/08 to remove not only the cyst, and to eliminate the possibility of future cyst problems.
I don't know about your uterus, but can talk with you about the cyst. It sounds like we have a similar problem there.
I wish you the best,
Morrowville
Sorry....I don't know much about dermoid cysts. You can still have kids with just one ovary.
Good luck.
