Are there any symptoms of liver cancer that a person should look out for?

Late signs. Liver cancer usually occurs in a diseased liver and often the signs of liver cancer are overshadowed by the existing disease. Consult this site for more info. http://www.ncbi.nlm.nih.gov/pubmedhealth/pmh0001325/.
Too late. By the time someone has symptoms from liver cancer (weight loss, pain, jaundice, loss of appetite), the cancer is usually advanced. To catch liver cancer at an early stage requires regular check with a doc. If a blood test shows abnormal liver tests, then an ultrasound can be obtained. Those at risk for liver ca, ( family history, hep b or hep c) should have regular ultrasounds and lab tests.
