Introduction: Liver cancer is the third leading cause of cancer deaths in the world after lung and stomach cancer, with about 600,000 deaths in 2002. A deadly cancer, It will kill almost all patients who have it within a year. In 1990, the World Health Organization (wHO) estimated that there were about 430,000 new cases worldwide,and a similar number of patients died as a result of this disease.

About three quarters of the cases are found in Southeast Asia (China, Hong Kong,Taiwan, Korea, and Japan). The frequency of liver cancer in Southeast Asia and sub-Saharan Africa is greater than 20 cases per 100,000 population. In contrast, the frequency of cases in North America and Western Europe is much lower, less than five per 100,000 population. However, the frequency of cases among native Alaskans is comparable to that seen in Southeast Asia.

CAUSE: The cause of liver cancer is often cirrhosis (scarring of the liver). It may be caused by viral hepatitis, primarily hepatitis B and C, alcohol abuse, hemochromatosis, various auto-immune diseases of the liver, as well as various other diseases that result in chronic inflammation of the liver.

SYMPTOMS: Many persons with liver cancer do not develop signs of it until the advanced stages of the tumor which usually makes prognosis poor. Symptoms may include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not show any symptoms and the disease may not be found until it is advanced.

Liver cancer patients often don't experience symptoms prior to diagnosis. As the disease progresses, symptoms begin to appear causing possible discomfort. If a patient has symptoms, his or her doctor may order special x-rays, such as a computed tomographic scan or a liver scan. If you experience any symptoms of liver cancer, you should report them to your doctor.

TYPES: Because the liver is made up of several different types of cells, many types of tumors can form in the liver. While there are other types of liver cancer, the most common form in adults is called hepatocellular carcinoma (huh-pat-uh-CELL-u-larcar-sin-o-muh). Doctors can identify several subtypes of hepatocellular cancer by looking at tissue under a microscope. Most of these subtypes do not affect treatment or the patient's outlook.

RISK: Risk factors for primary liver cancer include Having hepatitis, Having cirrhosis, or scarring of the liver, Being male, Low birth weight. Patients with associated cirrhosis caused by chronic hepatitis B or C infections, alcohol, and hemochromatosis have the greatest risk of developing this form of cancer.

The only hope for those who are at risk for this disease is routine surveillance so that the cancers can be diagnosed early. But the most important news about primary liver cancer is that you can greatly decrease your risk by protecting yourself from hepatitis infection and cirrhosis, the leading causes of the disease.

TREATMENT: Treatments for primary liver cancer depend on the extent (stage) of the disease as well as the persons age, overall health, feelings and personal preferences. Treatments that your doctor will consider include surgery, chemotherapy, radiation, and in a few instances liver transplantation.

Aggressive surgery or liver transplantation may be successful in treating small or slow-growing tumors if they are diagnosed early. Primary liver cancer is rarely discovered early and often doesn't respond to current treatments. Thus, the prognosis is often poor. Even when treatments fail to provide much improvement in the cancer itself, pain and other signs and symptoms caused by the disease can be aggressively treated to improve quality of life.

CONCLUSION: Cancer of the liver is the fifth most common cancer worldwide. It may be difficult to detect early because patients often have no symptoms and the cancer usually grows quickly. It is most often diagnosed when tumors from other parts of the body have spread to the liver (metastatic liver cancer), but can also more rarely arise directly in the liver (primary liver cancer). The tumor can originate inside the liver (primary liver cancer or hepatocellular cancer) or spread to the liver (metastatic liver cancer) from nearby sites, such as the colon.

Even though many cancers are declining in the US, new cases of primary liver cancer are growing. Although the current techniques for surveillance are not very good at detecting early cancer of the liver, newer techniques are being tested and appear to be better. Because standard treatments usually aren't effective against the disease, you may want to consider taking part in a clinical trial, a research study that attempts to improve current treatments or find new treatments. More studies are required to understand how targeted therapies may be used to control advanced liver cancer.
