Thank you so much for your reply. We had asked a few of their doctors about the possibility of HPV but we were told that wasn't the cause. We don't know for sure and never will. I really wish I knew about this web site before it is wonderful that patients and their caregivers can talk to other people in this terrible situation.

I am so very sorry about the loss of your sister. It is so hard to watch them fight and suffer.

Take Care,

Debbie
