Liver cancer, indeed, is a type of cancer in English. It refers to the growth of abnormal cells in the liver, which is the largest internal organ in the human body. The liver has many functions, including the production of bile to help with digestion, detoxification of harmful substances, and the storage of nutrients.
Liver cancer can be classified into two main types based on its origin:
Primary Liver Cancer: This is cancer that starts in the liver cells. The most common form of primary liver cancer is hepatocellular carcinoma (HCC), which accounts for about 70-85% of all primary liver cancers. Other types of primary liver cancer include cholangiocarcinoma, which originates in the bile ducts, and angiosarcoma, a rare type of liver cancer that begins in the blood vessels.
Secondary Liver Cancer: This is cancer that spreads to the liver from another part of the body. It is more common than primary liver cancer. The primary cancer may be in the lungs, breasts, colon, or other organs. When cancer spreads to the liver, it is often advanced, and the primary site of the cancer is what determines the type.
Liver cancer can also be categorized by the presence or absence of cirrhosis:
- Cirrhotic Liver Cancer: This occurs in individuals with liver cirrhosis, a condition where the liver becomes scarred and damaged, often due to chronic conditions such as hepatitis B or C, alcohol abuse, or non-alcoholic fatty liver disease.
- Non-Cirrhotic Liver Cancer: This occurs in individuals without liver cirrhosis.
Understanding the type of liver cancer is crucial for diagnosis, treatment planning, and prognosis. The diagnosis often involves imaging tests such as ultrasound, CT scan, MRI, or PET scan, and sometimes a liver biopsy to confirm the presence of cancer cells.
Treatment options can include surgery, ablation therapies, liver transplantation, chemotherapy, targeted therapy, immunotherapy, and radiation therapy, depending on the type, stage, and overall health of the patient. Liver cancer is challenging to treat, and its prognosis can be poor, especially in cases where it is detected late.
It’s important to note that while liver cancer is a serious disease, early detection and treatment can improve the chances of survival. Regular screenings and monitoring for risk factors are essential, particularly for individuals with a history of chronic liver disease or heavy alcohol use.
