Liver cancer is a type of cancer that starts in the liver, an important organ that helps digest food and filter toxins from the blood. It can develop from liver cells or from other cells in the liver. The most common type is called hepatocellular carcinoma, which often occurs in people with chronic liver diseases, such as cirrhosis or hepatitis. Symptoms of liver cancer may include weight loss, loss of appetite, and abdominal pain. Early detection is crucial for better treatment outcomes. Treatments can involve surgery, chemotherapy, or targeted therapies, depending on the stage of the cancer and the overall health of the patient.
