Benign
These brain tumors are not as harmful as the other type, because they have a low proliferating rate. They don’t invade tissues distantly, the surrounding areas. These tumors do not cause cancer, however, these might cause problems and effect the proper functioning of the human body, because an increase in the size of any area of the brain causes pressure on the adjacent side.
