Michael Roizen, MD, Internal Medicine, answeredSome tumors don't have cancer cells; this means that they're benign. However, the dictionary definition of 'benign' doesn't apply perfectly here, because a benign tumor can still be dangerous. Why? Benign tumors can grow to block off the pathway of important nutrients and bloody supply throughout the body. That's why surgery is sometimes necessary to remove benign tumors-to re-open the roads for nutrients to get to the organs.
