Liver tumors are abnormal growths that occur in the liver, which is a vital organ responsible for filtering blood and producing bile. These tumors can be classified as benign (non-cancerous) or malignant (cancerous). Common types of liver tumors include hepatocellular carcinoma, which is the most prevalent form of liver cancer, and hemangiomas, which are usually harmless. The causes of liver tumors can vary, with factors such as chronic hepatitis B or C infections, excessive alcohol consumption, and obesity increasing the risk. Symptoms may include abdominal pain, weight loss, and jaundice, but some individuals may not experience any noticeable signs until the tumor is advanced. Early detection and treatment are crucial for better outcomes.
