Liver cancer (hepatocellular carcinoma): Causes
The liver cancer causes are not clear yet. A risk factor for hepatocellular cancer (hepatocellular carcinoma) is a permanent cell damage caused by hepatitis viruses. Particularly an infection with the hepatitis B virus can lead to liver cancer. The risk is higher, the longer the infection is: who was infected at birth with hepatitis B because of the duration of the infection, has a higher risk of developing over the life of liver cancer, as someone who is infected later , Also chronic hepatitis C infection is a risk factor.
In the Western industrialized nations, primary liver cancer (even coming from the liver malignant tumors) develops mostly in people who have liver cirrhosis (scarring cirrhosis) suffer. It can occur as a result of hepatitis or a long-term excessive alcohol abuse.
In addition to these liver cancer causes, there are other points that increase the risk of primary liver cancer (hepatocellular carcinoma, for example):
If there are several factors before at the same time, it significantly increases the risk of liver cancer.
The causes of occurring less frequently Cholangiocarcinoma (Bile duct cancer, cholangiocarcinoma) are also not fully understood. Research suggests that some diseases are risk factors being:
Also, smoking and advanced age appear to increase the risk of cancer of the liver and bile duct cancer.
