As the liver cancer grows, symptoms may include weakness, felling tired, poor appetite and as a result a loss of weight, bloating (swollen) abdomen, pain in the upper abdomen on the right side (the pain may reach back and shoulder), yellow color of skin and eyes, waves of nausea, sometimes dark urine because of jaundice and even fever. The duration of liver cancer symptoms is generally between 1 week and 6 months, but some people can live with them as long as 2 years.

In the course of time the liver cancer pathology is almost always enlarged and usually fragile, its surface may be irregular and a definite mass may be felt. An enlarged spleen may be present and is attributed to the hepatic fibrosis and consequent portal hypertension that are also complications of exposure to vinyl chloride monomers.

Approximately, 15 per cent of patients present with acute hemperitoneum following tumor rupture. Though these symptoms are not sure signs of liver cancer diagnosis. Many of them are hazy and other health problems can also cause these indications. Anyone with these symptoms should visit a doctor as soon as possible. Only a doctor can provide the liver cancer diagnosis and cure the problem.

There are some risk factors:

Chronic liver infection (hepatitis) - certain viruses can infect the liver. The infection may be chronic. (It may not go away). The most important risk factor for liver cancer is a chronic infection with the hepatitis B virus or the hepatitis C virus. These viruses can be passed from person to person through blood (such as by sharing needles or sexual contact).

An infant may catch these viruses from an infected mother. Liver cancer can develop after many years of infection with the virus. These infections may not cause symptoms, but blood tests can show whether virus is present.

Cirrhosis - Cirrhosis is a disease that develops when liver cells are damaged and replaced with scar tissue. Cirrhosis may be caused by alcohol abuse, certain drugs and other chemicals, and certain viruses or parasites.

Aflatoxin - Liver cancer can be caused by aflatoxin, a harmful substance made by certain types of mould. Aflatoxin can form on peanuts, corn, and other nuts and grains. In Asia and Africa, aflatoxin contamination is a problem.

There are also some groups of high risk depending upon genus, family history or age. Men are twice as likely as women to get liver cancer. People who have family members with liver cancer diagnosis may be more likely to get the disease. In the United States, liver cancer diagnosis occurs more often in people over age 60 than in younger people. The more risk factors a person has, the greater the chance that liver cancer will progress. However, many people with identified risk factors for liver cancer pathology do not develop the disease.

After the doctor has settled that a person's symptoms are associated with angiosarcoma liver cancer or a primary liver cancer (not a cancer that has started elsewhere in the body and spread to the liver), a person may have blood tests called liver function tests (LFT). These display if the liver is working properly. It is important to remember that the normal working of the liver can be affected by many conditions other than cancer. LFTs are also useful as an indicator of how well the liver works before, during and after the treatment.
