The spleen is one of the organs that holds many vital functions of the body, helping to produce blood cells, store blood, but also create antibodies capable of fighting viruses that attack the immune system. An enlarged spleen indicates that the body has an infection, or some other health problem. Early diagnosis and treatment are essential to prevent potentially dangerous complications.

The spleen produces white blood cells, which are the building blocks for antibodies, and it also contains a large number of lymphocytes. Removing the spleen means your immune system will be weakened.
