Expert Response
Canker is the more general term, meaning a dead area in the bark or stem of a plant. It can be caused by many things.
A burl is a more specific term, but also has several causes. A virus, fungus or injury stresses the tree and the tree reacts with a mass of stunted buds that remain dormant and never develop. This mass is woody and covered with bark. It produces beautifully grained woods and is prized by woodworkers.
