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 cells in other parts of the liver, such as bile ducts. Common causes include chronic liver diseases like hepatitis and cirrhosis, which can damage liver tissue over time. Symptoms of liver cancer may include weight loss, abdominal pain, and jaundice, which is a yellowing of the skin and eyes. Early detection is crucial for better treatment options, so regular check-ups are important, especially for those at higher risk due to conditions like hepatitis or heavy alcohol use.
