thank you guys for the replies. my friend finished radiation last december. he also had 2 open biopsies last june,the wound from the last biopsy hasn't healed completely up to now. He also had 2 sessions of chemo but his family decided to stop it after they got the MRI result which showed that the mass size has grown double since last month. They read somewhere that O2 treatment might help so we're trying that one now. We are also trying alternative medicine. We are desperate to find treatment for him. I feel so helpless seeing him suffer so much.
