Liver cancer is a type of cancer that originates in the liver and is categorized into two main types: Primary liver cancer and Secondary liver cancer. This type of cancer is highly prevalent in Africa and Asia.
Primary liver cancer can be classified into four main types, each of which has distinct characteristics. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, also known as hepatoma, and typically begins in the liver’s main cells called hepatocytes. Fibrolamellar HCC, on the other hand, is a rare form of liver cancer that primarily affects younger individuals, and its causes and risk factors are still unknown. Bile duct cancer, also known as cholangiocarcinoma, is a type of liver cancer that arises in the cells lining the bile duct, which is part of the digestive system. Angiosarcoma is a highly uncommon type of liver cancer that begins in the blood vessels of the liver and is a form of soft tissue sarcoma. Additionally, haemangiosarcomas are angiosarcomas that develop in blood vessels.
In contrast, secondary liver cancer is a cancer that originates elsewhere in the body and spreads to the liver. This type of cancer is also referred to as metastatic cancer in the liver. It is crucial to consult with a healthcare professional for prompt diagnosis and appropriate treatment, as early detection of liver cancer can lead to better treatment outcomes.
