My 40 year old son had brain surgery in June, 2011.
He had three hemangio-pericytoma tumors. They removed
two and he had 35 radiation treatments to the third.
In April, 2012 he started having pain and thought it was
his appendix........turns out the tumors had moved into the
liver/stomach area. He is now taking chemo. Has anyone heard
of these tumors moving to other parts of the body?
