Whitebeam defoliation July

[travis]

I have a whitebeam at home, I’ve known it for 8 yrs, this July the tree lost about 80% leaf cover and since lost nearly all leaves by September.  Before me the tree had been pruned with a pole or similar leaving decay and fungus to develop, I suppose they had the intention to pollard or similar.  I have tried to target prune and remove the decay.  That was 6 or 7 yrs ago,  I noticed swelling at the base of the trunk and damp looking inclusions low down at the first unions/divisions.  Our Apple tree looks to have Apple canker disease, am I right to understand this can affect sorbus, and whitebeam?

Yes you can get Nectria canker on sorbus

So, I didn’t quite get to the point.  I want to know, is the tree going to recover, is there anything I can do to help?
