What is liver cancer?

Liver cancer, also known as hepatic cancer, is a type of cancer that starts in the liver. The different types of liver cancer are

  • Primary liver cancer: This cancer originates in the liver. Primary liver cancer is of different types
    • Hepatocellular carcinoma (the most common form of liver cancer)
    • Intrahepatic cholangiocarcinoma (bile duct cancer)
    • Angiosarcoma and hemangiosarcoma (cancer that begins in the cell lining of the blood vessels in the liver)
    • Hepatoblastoma (cancer containing immature cells, generally occurring in infants and young children)
  • Secondary liver cancer (metastatic liver cancer): Cancer originating in other parts and migrating to the liver.
  • Benign liver tumors: Noncancerous tumors may grow large enough to cause problems, but they do not invade nearby tissues.

What are the sources of pain in liver cancer?

People with liver cancer or advanced stage liver cancer may experience pain from various sources, including

  • Tumors: Tumor or tumors in the liver can cause excess pain.
  • Capsule stretching: Stretching of the capsule around the liver can cause discomfort.
  • Referred pain: Referred pain is caused by the enlarged liver pressing on the nerves under the diaphragm. It may give rise to pain in the right shoulder because some of the nerves under the diaphragm connect to nerves there.
  • Treatment: Cancer medications and treatment may cause pain and discomfort. Also, surgery can cause postoperative pain.
  • Underlying medical conditions: If cirrhosis is the cause of liver cancer, pain may be attributed to cirrhosis and not to cancer.
