Risk Factors for Bile Duct Cancer
A risk factor is something about you that increases your chance of getting a disease or having a certain health condition. Some risk factors for bile duct cancer you cannot change, but some you can. Changing the risk factors that you have control over will help you live a longer, healthier life.
Risk factors do not mean that you will get the disease. Many people who have these risk factors do not develop the disease and many who develop the disease did not have any of these risk factors.
