The United States has by far the largest correctional system in the world. It is so large, in fact, so sprawling and dispersed, so administratively complex that just how many people are incarcerated is uncertain. The most commonly cited statistic is that are about 2.3 million inmates on any given day.
Most often, a lump in the abdomen is caused by a hernia. An abdominal hernia occurs when there is a weak spot in the abdominal wall. This allows the internal organs to bulge through the muscles of the abdomen. A hernia may appear after you strain, or lift something heavy, or after a long period of coughing. Inguinal hernia appears as a bulge in the groin or scrotum.
Hernia Overview. A hernia occurs when the contents of a body cavity bulge out of the area where they are normally contained. These contents, usually portions of intestine or abdominal fatty tissue, are enclosed in the thin membrane that naturally lines the inside of the cavity. Hernias by themselves may be asymptomatic (produce no symptoms) or cause slight to severe pain.
