is bile duct cancer hereditary
But inherited gene mutations are not thought to cause very many bile duct cancers. Gene mutations related to bile duct cancers are usually acquired during life rather than being inherited. For example, acquired changes in the TP53 tumor suppressor gene are found in most bile duct cancers.Other genes that may play a role in bile duct cancers include KRAS, HER2, and MET. Some of the gene changes that lead to bile duct cancer might be caused by inflammation.But sometimes what causes these changes is not known. Many gene changes might just be random events that sometimes happen inside a cell, without having an outside cause.ut inherited gene mutations are not thought to cause very many bile duct cancers.
