Benign tumors are made up of normal cells growing in the wrong place or growing at a time when they are not needed. They grow by expansion rather than invasion and often are encapsu-lated. The size and the fact that it is painless does not mean that the tumor is benign. Additional-ly, the presence of any sensation (such as itching) does not rule out malignancy.
