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. ==Classification== There are many forms of '''liver tumors''': ===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 stem cell|mesenchymal]] tissue, [[sarcoma]] and [[hepatoblastoma]], a rare malignant tumor in children. ===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]] ==External links== * [http://pathology2.jhu.edu/liver/ The Liver Cancer Web Page] at [[Johns Hopkins University]] * [http://www.mayoclinic.com/health/liver-cancer/DS00399/ Liver cancer] at [[Mayo Clinic]] * [http://www.bluefaery.org/ Blue Faery: The Adrienne Wilson Liver Cancer Association] {{Digestive system neoplasia}} [[Category:Hepatology]] [[de:Leberkrebs]] [[ko:간암]] [[hu:Májtumor]] [[nl:Leverkanker]] [[ja:肝癌]] [[fi:Maksasyöpä]] [[pl:Nowotwory wątroby]] [[sv:Levercancer]] [[ur:سرطان جگر]] [[zh:肝癌]] {{oncology-stub}} [[Category:Oncology]]
