Canker

Canker (/ˈkæŋkər/), from the Old English cancer, is a broad term often used to describe a variety of sores or ulcers that can develop in different areas of the body.

Etymology

The term canker is derived from the Old English cancer, which is akin to the Greek word karkinos, meaning crab or cancer. It was used to describe a spreading sore that eats into surrounding tissue, much like a crab burrows into sand.
