My dad and I just got the phone call his cancer has returned. We will be going in for a biopsy in the next couple of days, waiting on the call to know when for sure. He has already had half of his lung removed, and been thru chemo and radiation, and we were warned if the same cancer returned, that further treatment would be futile. Please keep him in your prayers that this is a different cancer, and that God will help him deal with this blow, he is pretty devastated.
