prayer request

I got this email from one of my kids from a former parish. I have taken out his town and last name, even though his father wants his story told as stated at the end of the email, ya know, just for safety or privacy's sake. But this young man needs your prayers, so if you could put him on your list I'm much appreciative.
I know this young man. He's a great guy, and it's so awful, after all he's already been through, that this is happening to him again. Please help me pray for him.

Hello family and friends,
I am writing you to ask you all to pray for a 17 year old student with brain cancer. He received a clean bill of health 5 years ago and learned in May of this year that the cancer has returned and is now in 6 areas of his brain. He is not a candidate for chemotherapy or radiation at this point. His only hope is an alternative treatment which his father is administering at home, through IV. The treatment causes a high fever of 105 degrees and makes the young man very ill. The hope is that the toxins that are injected will kill the tumors. Brain damage is now occurring; either due to the tumors or the toxins.
Please pray for the father and mother who are trying relentlessly to save their son; the son who is experiencing this pain and suffering and the rest of the family who include 4 siblings. The father, who I spoke to today, wants prayers and believes it is the only hope. He also wants his son's name to not be anonymous. His name is David. Thank you for including him in your prayers.

Thanks all.
