Hello,
While pruning my thornless blackberry plant, I noticed these galls on its canes.
FYI, my plant is two years old. I live in southern Quebec. 2/3 of the plant was covered with snow almost the entire winter.
This gall is located at the bottom of the cane:

This one is located in the middle on a different cane:

I only have two strong big canes and a skinny one. Can someone explain exactly what they are, and if I should do something about them?
Extra info:
Last summer, cane borers attacked my raspberry plants. I was able to cut off the tilted tips and save the canes. The source of the problem was a small sick tree nearby that was infested with aphids and other insects. I saw borers too. After I removed the tree, no more tilted tips.
They might have laid eggs on my blackberry canes, but I did not see any tilted tips. I check my plants almost everyday during summer.
