text: what is a spleenic lesion and how is it treated? i was told thati had a lesion on my spleen,but the dr.told me that she had real patients and to go home.what should i do? spleen is an organ in the body that 'recycles' blood. it destroys the worn out rbcs (which carry oxygen and carbon dioxide). lesion=any structural change in an organ associated with alteration in function. i don't know what's the splenic leion that u r suffering from- seems like u r quating an uktrasonography report. u could be suffering from 'hypersplenism', in which case there is increased destruction of rbcs resulting in anemia with enlargement of spleen (located to the left slightly above the stomach) and is treated by removal of spleen (splenectomy). splenectomy, i guess, is a pretty safe procedure, and one of its complications could be recurrent infections. if ur spleen is enlarged u'll experience heaviness and pain/discomfort in the above-mentioned region. don't neglect this condition, since an enlarged spleen is prone to rupture, which results in heavy blood loss and can be instantaneously fatal.
