The liver is an organ about the size of a football. It sits just under your rib cage on the right side of your abdomen. The liver is essential for digesting food and ridding your body of toxic substances.
Liver disease can be inherited (genetic). Liver problems can also be caused by a variety of factors that damage the liver, such as viruses, alcohol use and obesity.
Over time, conditions that damage the liver can lead to scarring (cirrhosis), which can lead to liver failure, a life-threatening condition. But early treatment may give the liver time to heal.
Surgeons mostly perform a partial liver resection to remove a cancerous, precancerous or benign (noncancerous) tumor. Liver cancer can be primary — which means that it originates in the liver — or it can be secondary, which means that it originates in another organ and spreads.
Treatment for liver disease depends on your diagnosis. Some liver problems can be treated with lifestyle modifications, such as stopping alcohol use or losing weight, typically as part of a medical program that includes careful monitoring of liver function. Other liver problems may be treated with medications or may require surgery.
Treatment for liver disease that causes or has led to liver failure may ultimately require a liver transplant.
