There is very often talk on this site of how long people have survived after treatment for oc.
I have just returned from a pilgrimage to Israel and was delighted to find out that one of our group was a survivor of more than twenty years standing. She had two very large cancerous cysts that her surgical team had great trouble removing and she underwent chemo therapy afterwards but has not received any treatment since.
I know everyone is different but I was so glad to talk to her and she was quite happy for her story to go on this site.
So, never give up!!
