Could benign tumors still kill you?

Yes: Benign tumors, especially in the brain , can kill you as they can grow and damage adjacent brain or cause increased pressure on the brain. Benign lung or GI tumors can cause obstructive pneumonia or bowel obstruction with dire consequences. Benign tumors in virtually any organ can cause irreparable damage if growth is unchecked or the tumors are not removed. Expert consultation is important.
