Liver cancer develops when abnormal cells grow uncontrollably in the liver. Common risk factors include chronic hepatitis B or C infection, liver cirrhosis, long-term alcohol use, fatty liver disease, obesity, and exposure to harmful toxins. Early symptoms may be mild but can include weight loss, loss of appetite, persistent fatigue, abdominal pain or swelling, nausea, and yellowing of the skin or eyes (jaundice). Treatment depends on the cancer stage and liver health, and may include surgery, liver transplant, chemotherapy, targeted therapy, immunotherapy, or radiation. Early diagnosis improves treatment outcomes and survival rates.
