Treatment? Removal? Thoughts? It's an Oak tree. Not sure what kind.

Burls. Do not remove, you will just create a larger wound. Have periodic assessments done to keep track of the condition of the trees overall. Use a qualified arborist to perform these evaluations and insist on a written report.

Almost looks like the burls were cut off???

Woundwood on edges?

could that be some kind of nectria canker? Looks like it has tried to compartmentalize multiple times.

I was going to guess Nectria. I have seen (rarely) similar patterns on oaks where the infection did not seem to advance much but the tree could not fully compartmentalize. Kind of a standoff.

Be concerned only if limbs are overextended (sticking way out) and even then respond with a light reduction. Especially if a lot of these are on the upper (tension) sides of the limbs. Got pics of the whole tree?
