A lump in the abdomen is a soft bulge of tissue or a small area of swelling in the belly.

Most often, a lump in the abdomen is caused by a hernia. An abdominal hernia occurs when there is an area where the muscles are weak.

Surgery may be needed to correct incisional hernias or umbilical hernias that do not go away by the time a child approaches school age. The surgery may be done through a large surgical cut, or through a smaller cut into which the surgeon inserts a camera and other instruments.
Emergency surgery is needed in the case of a strangulated hernia.
