thank you for your information. I will wait and see what the doctor says. after some research I am pretty much aware of the situation. only 2-4% of dermoid cysts are bad ones and the rest of them are good but will grow as you said. It might be twisted if it goes too large. I will consider remove it if there is a risk for the baby. After posting the question just knew that my husband's aunt had the same problem but only found out after conception and it was too late to have it removed. The doctor took it out when delivering the baby. It will be the best choice for me if the doc reckon the risk is low.
Thanks again.

In my opinion, it doesn't sound like you need to worry about ovarian cancer. I had a friend who had PCOS and had many troubles but eventually conceived twice and had two healthy babies. Dermoid cysts can grow large and even burst and cause problems. I have known three people who had dermoid cysts and none of them were malignant. I would go with my drs. recommendation on that. It would be better to have it removed before conception rather than complicate your pregnancy. Dermoids are very rarely cancer. Even if it were, in early stages you could just have that ovary removed and still have a good chance of conception with the other ovary. Keep the faith. Best wishes.
