Does anyone know what these black lumps on a bunny were?

So I saw a wild bunny, and it had two black lumps on it, one hanging off it’s chin and another on its side. It looks to be a pretty small bunny. But these black lumps had the size & shine of a bunny’s eyeball, and I was curious to know what was going on. Is it some type of tumor/cancer? Or is it a birth defect?... show more So I saw a wild bunny, and it had two black lumps on it, one hanging off it’s chin and another on its side. It looks to be a pretty small bunny.

Is it carrying a contagious disease? My dog went near it, and was by him for about 15 seconds before I saw the bunny, so I want to know if it was potentially carrying a harmful disease.
