Expert Response
Cankers and root collar rot are the major diseases of honey locusts because they can girdle the stem and kill the tree. Canker disease symptoms include sunken, dead areas of bark; dieback; reduced foliage; yellow foliage; premature fall coloration; and early leaf drop.
A photo would help to diagnose the problem further.

Have you used any herbicides near the tree? Or any weed and feed lawn applications near the tree?
Yes, the tree is within a few feet of my backyard lawn. It was infested with chinch bugs and was treated. I also applied fertilizer before that.

If the lawn applications included a formulation that "kills weeds" it may affect your tree as you have shown by the photos.
The tree will most likely recover.
You can prune off the deformed growth to encourage new growth.
