Thanks for posting your query.
Spleen is lymphoid organ of the body normally its size is less than 13 cm .The causes of an enlarged spleen are multiple, most reflect the presence of hepatic or hematologic disease, infection, or inflammation. If you have no history of alcoholism and live disease (hepatitis) then haematological conditions like polycythemia vera,Chronic myeloid leukemia
,Myelofibrosis or Lymphoma should be ruled out.
You are advised to visit hematologist
and get tests like complete blood count
with white blood cell
differential and platelet count
and examination of the peripheral blood smear, liver function studies, urinalysis, and chest x-ray. Testing for the presence of antibodies to HIV should be considered when no other causes for splenomegaly are apparent.
Hope it helps.
