      Discrimination between a benign tumor and a malignant one in the liver is an essential clinical problem. The most commonly found benign tumors in the liver are cysts, cavernous hemangioma, focal nodular hyperplasia, adenoma, fatty infiltration and regenerative nodules, followed by less common le-sions such as liver abscess and angiomyolipoma.

      Differences Between Benign and Malignant Tumors There are many important differences between benign and malignant tumors which are as follows: i. On the Basis of Growth rate: Generally malignant tumors grow more rapidly than benign tumors, although there are slow-growing and fast-growing tumors in either category. ii.
