Hello Sergio:
I just wanted to welcome you to the Forum; I don't know about your type cancer, but there are a lot of others on the Forum with that experience and knowledge who will be joining in to help you. I can offer my prayers that you'll soon find out the solution to your hurting and that you will be pain free. It sounds like you have already been through a lot, but don't give up. Others have had like experiences. Bless you.
