I am so sorry Sarah for your ongoing trauma - you are sounding very brave to me.
I agree with all the other ladies -you MUST get another opinion. perhaps even from a gynological oncologist -they specialise in cancerous/precancerous issues of women's bits! May cost a little to see a specialist but what price do you put on your life and the potential to have more children. What a very tough choice for you -I'm not sure what I would do except to investigate EVERY possible option and be sure I trusted the people looking after me.

All my love to you and your family
