Spleen neoplasms, also known as splenic tumors, are rare types of cancers that originate in the spleen. These tumors can be benign (noncancerous) or malignant (cancerous) and can vary in size and aggressiveness. Although not extensively studied, the available medical literature reports some synonyms for spleen neoplasms. These include terms such as splenic tumors, splenic masses, splenic lesions, and splenic growths. While these terms all refer to the abnormal growths in the spleen, it is important to consult with a healthcare professional for a precise diagnosis and proper treatment plan as the terms used may depend on the specific characteristics of the neoplasm.
