Malignant tumors of the liver are most commonly metastases, or areas of distant spread, from tumors that arise elsewhere in the body. These tumors are not true liver cancers; instead they are named by their site of origin, such as lung cancer metastatic to the liver. True liver cancers are malignancies that arise in the cells of the liver. Symptoms of liver cancer arise most commonly in the later stages of the disease and include weight loss, nausea, vomiting, loss of appetite, fatigue, and abdominal swelling. These symptoms are fairly nonspecific and can occur with cancers in other locations as well as some chronic diseases. Other symptoms of liver cancer include a yellowish discoloration of the skin and whites of the eyes (jaundice), enlarged and tender liver, and chalky, white-colored stools.
