Gum and Canker issues with Red Haven Peach trees #824153

I have two Red Haven (or variant ) peach trees that have various issues with what appear to be canker spots, as well as gumming around the canker and trimming locations. In some cases, there is gumming without any open canker, but the bark looks abnormal.

Gumming can result from any injury. Picture 3 appears to be a case of peach borer, probably the lesser peach tree borer. (see the attached picture). Probe around for larvae still in the wood.
For pictures 1 and 2, my first guess would be mechanical damage from pruning or other activity that did not heal properly. Areas of cold damage can result in gumming some years later. Deer antler rubbing is another possibility to consider.
