A benign tumor does not spread to other body parts like malignant cancers can. But most benign tumors or cysts of the head and neck region will, however, get slowly and progressively larger, destroying normal tissues as it progresses. Problems these entities may create include the destruction of normal tissues or the compression of nerves, blood vessels, or other structures. A tumor may obstruct a patient’s mouth, block the nose, or invade the eyes. In other cases, a patient may want to remove a benign tumor because of its appearance.
