Can a tree with canker be saved?
A canker that has girdled more than about half the trunk circumference is structural, not cosmetic. Small branch cankers can be pruned out; trunk cankers usually can't.
Timing
Prune out affected branches in dry weather, well below the canker.
Indiana specifics
Common on stressed honey locust and on trees with mower or string-trimmer damage at the base — which is a genuinely avoidable cause.
