==Overview==
'''Hepatic tumors''' are tumors or growths on or in the [[liver]] (medical terms pertaining to the [[liver]] often start in ''hepato-'' or ''hepatic'' from the [[Greek language|Greek]] word for liver, ''hepar''). These growths can be [[benign]] or [[malignant]] (cancerous). They may be discovered on [[medical imaging]] (even for a different reason than the [[cancer]] itself), or may be present in patients as an abdominal mass, [[hepatomegaly]], [[abdominal pain]], [[jaundice]], or some other [[liver]] dysfunction.
 
==Forms==
 
There are many forms of '''liver tumors''':
 
====Malignant====
* Malignant (cancerous):
** Most cases are '''[[metastases]]''' from other [[tumor]]s, frequently of the [[GI tract]] (like [[colon cancer]], [[Carcinoid syndrome|carcinoid tumors]] mainly of the [[appendix]], ''etc''.), but also from [[breast cancer]], [[ovarian cancer]], [[lung cancer]], [[renal cancer]], [[prostate cancer]], ''etc''.
** The most frequent, malignant, primary liver cancer is '''[[hepatocellular carcinoma]]''' (also named ''hepatoma'', which is a misnomer because [[adenoma]]s are usually benign).
** More rare primary forms of liver cancer include [[cholangiocarcinoma]], mixed tumors, tumors of [[mesenchymal]] tissue, [[sarcoma]] and [[hepatoblastoma]], a rare malignant tumor in children.
 
====Benign====
* Benign:
** Hepatic [[Hemangioma]] are the most common liver tumors, found in up to 7% of autopsy specimens.
*** A rare tumor is [[Infantile Hemangioendothelioma]].
** [[Hepatic Adenoma]], mainly in women using estrogens as contraceptives, or in cases of steroid abuse
** [[Focal nodular hyperplasia|Focal Nodular Hyperplasia]]
** [[Nodular Regenerative Hyperplasia]]
** [[Hamartoma]]
