Liver cancer, also known as hepatocellular carcinoma (HCC), is a type of cancer that originates in the liver cells. It can develop from various causes, including chronic liver disease, such as cirrhosis, hepatitis B or C infection, heavy alcohol consumption, and fatty liver disease. Symptoms may not appear in the early stages, but as the cancer progresses, they may include abdominal pain, unexplained weight loss, jaundice, and swelling in the abdomen. Treatment options depend on the stage of the cancer and may include surgery, chemotherapy, radiation therapy, targeted therapy, or liver transplantation. Early detection and treatment are essential for improving outcomes and survival rates.
