An abdominal mass is an abnormal growth in the abdomen. It may occur as the result of an underlying condition that can range from benign and asymptomatic to serious, including certain cancers. A patient with an abdominal mass is likely to feel bloated, pain, and discomfort, but it is also possible to experience no symptoms. Normally, you will be able to feel the mass by probing the lower stomach. Symptomatic or not, the mass may affect the surrounding organs and intestines.
Abdominal masses may develop anywhere in the abdomen. They may be within the flesh or fat of the stomach, on the abdominal muscles, or attached to an organ. The abdomen has four quadrants: the upper right, upper left, lower right, and lower left. The location of the mass helps doctors determine which organ or structure within the abdomen is affected. Organs that may be affected include the liver, kidneys, stomach, pancreas, uterus, ovaries, and appendix.
