We just learned about the Neoplasm.
Another thing that happens to the human body is a Benign tumor.
Remember that a neoplasm is really just a bunch of extra cells that the body made that aren't supposed to be there.
Sometimes they are a lump you can see on the outside of someone's body, and sometimes they are inside the body on the organs.
If a tumor is staying where it is at, and is not spreading through the body then it is called benign.
That usually means it is not very bad and is not hurting a person.
