The spleen is an organ in the upper part of your abdomen (belly) that works like a filter, removing bacteria and dead red blood cells from your bloodstream. In some cancers, the spleen may be removed or treated with radiation, causing it to not work as it should. This condition is called “asplenia.”
Removal of the spleen (or radiation to the spleen) puts you at higher risk for infections caused by certain types of bacteria. Streptococcus pneumoniae and Haemophilus influenzae type b are the most common infections after a splenectomy. An infection can quickly turn to sepsis, which is a life-threatening reaction in your body. Sepsis can lead to death if not treated quickly with antibiotics. Some experts think survivors with asplenia should have antibiotics on hand to start taking at the first sign of infection, even before being seen by their healthcare team. Talk with your provider to see if they want you to do this.
