Definition of Benign

Benign: Not cancer. Not malignant. A benign tumor does not invade surrounding tissue or spread to other parts of the body. A benign tumor may grow but it stays put (in the same place).

In a general sense, "benign" means of a mild character that does not threaten health or life. Floaters in the eye are benign. They have no significant effect on vision.
