Sounds like you're describing the early stages of Black Knot. It's a fungal infection that's very common in New England. The initial stage kills off the new(er) growth. It doesn't sound like borers. If you had borers the problem wouldn't be so localized and you would see tiny holes in the trunk and larger branches. You need to prune off all the dead growth dipping your shears in alcohol or bleach after every cut so as to not spread the infection. Then treat the tree with a fungicide suitable for this type of infection. Check your local nursery or farm supply outlet for what's available locally. Cherry trees are probably the most difficult fruit tree to grow due to their susceptibility to a number of fungal diseases, black knot being the most common.
