These are really weird. What is it? It's on my dad's apple trees in East Tennessee.

It looks like gall to me. I lost a couple grape vines to it several years ago:

Thank you for this. If it is a gall do you think he should look at treating it, or removing it immediately? He is very concerned about it spreading to his other trees. My instinct is to get rid of it, just to be safe, but I also hate to advise him to kill what might be a treatable tree. What do you think?

I chose to remove and destroy our infected grapes as it seemed to want to spread quickly.
