Another prayer request for the fam'

My dad recently got word that he's going to be heading back to Mayo to get those tumors on his liver removed. They're going to do a hi-res scan and then open him up to go over the organ with a fine toothed comb. It's scheduled for a month from now. Any and all your prayers would be welcome.

I'd be happy for them to actually find the tumors and finally get rid of them, although I'd be happier if they disappeared like the last couple times but didn't come back.

Saints Luke and Peregrine, pray for us.
