Kolangiokarsinoma: Perbedaan antara revisi

Faktor risiko untuk kolangiokarsinoma antara lain adalah ''primary sclerosing cholangitis'' (penyakit [[radang]] saluran empedu), [[kolitis ulserativaulseratif]], sirosis, [[hepatitis C]], [[hepatitis B]], infeksi cacing hati tertentu, dan beberapa malformasi hati kongenital.<ref name=":0" /><ref name=":2">{{Cite journal|last=Razumilava|first=Nataliya|last2=Gores|first2=Gregory J.|date=2014-06-21|title=Cholangiocarcinoma|url=https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(13)61903-0/abstract|journal=The Lancet|language=English|volume=383|issue=9935|pages=2168–2179|doi=10.1016/S0140-6736(13)61903-0|issn=0140-6736|pmc=PMC4069226|pmid=24581682}}</ref><ref>{{Cite journal|last=Steele|first=Jennifer A.|last2=Richter|first2=Carsten H.|last3=Echaubard|first3=Pierre|last4=Saenna|first4=Parichat|last5=Stout|first5=Virginia|last6=Sithithaworn|first6=Paiboon|last7=Wilcox|first7=Bruce A.|date=2018-05-17|title=Thinking beyond Opisthorchis viverrini for risk of cholangiocarcinoma in the lower Mekong region: a systematic review and meta-analysis|url=https://doi.org/10.1186/s40249-018-0434-3|journal=Infectious Diseases of Poverty|volume=7|issue=1|pages=44|doi=10.1186/s40249-018-0434-3|issn=2049-9957|pmc=PMC5956617|pmid=29769113}}</ref> Namun, kebanyakan orang tidak memiliki faktor risiko yang dapat diidentifikasi.
