<p>'''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.</p>
<p>There are many forms of '''liver tumors''':<br />
* Malignant (cancerous):<br />
** 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''.<br />
** The most frequent, malignant, primary liver cancer is '''[[hepatocellular carcinoma]]''' (also named ''hepatoma'', which is a misnomer because [[adenoma]]s are usually benign).<br />
** More rare primary forms of liver cancer include [[cholangiocarcinoma]], mixed tumors, tumors of [[mesenchymal]] tissue, [[sarcoma]] and [[hepatoblastoma]], a rare malignant tumor in children. There is currently no cure.</p>
<p>* Benign:<br />
** Hepatic [[Hemangioma]] are the most common liver tumors, found in up to 7% of autopsy specimens.<br />
*** A rare tumor is [[Infantile Hemangioendothelioma]].<br />
** [[Hepatic Adenoma]], mainly in women using estrogens as contraceptives, or in cases of steroid abuse<br />
** [[Focal nodular hyperplasia|Focal Nodular Hyperplasia]]<br />
** [[Nodular Regenerative Hyperplasia]]<br />
** [[Hamartoma]]</p>
