Hepatitis B virus (HBV) disease is the main causes of liver cancer. Liver cancer relates to the regularity of chronic hepatitis B virus disease. Studies in animals also have provided that hepatitis B virus can cause liver cancer. For example, liver cancer develops in other mammals that are obviously infected with hepatitis B virus-related viruses. As a final point, by infecting transgenic mice with certain parts of the hepatitis B virus, scientists caused liver cancer to develop in mice that do not usually develop liver cancer.
It is not easy to find out what causes cancer from one person to another, but researchers have found several factors that add to a person's likelihood of developing liver cancer. Some risk factors for liver cancer include:
Viral hepatitis – Researchers have linked the disease of hepatitis-B virus (HBV) and hepatitis-C virus (HCV) with the progress of liver tumor. It is estimated that 10-20 percent of people with HBV will increase liver malignancy, and HBV is present in about one fourth of cases of liver cancer in the United States.
Exposure to aflatoxin – This is a carcinogenic body that can be found in molds that may infect peanuts, corn, grains and seeds. In tropical and subtropical regions, measures have been taken to change and get better storage in order to decrease exposure to aflatoxins.
Cirrhosis – The Countrywide Cancer Institute estimates that 5-10 percent of people with cirrhosis will develop liver tumor. Cirrhosis caused by viral hepatitis B and C, alcohol abuse and certain genetic disorders puts people at higher risk for developing liver malignancy.
Exposure to vinyl chloride and thorium dioxide – Revelation to these chemicals is more to be expected to cause angiosarcoma of the liver, a different type of tumor than HCC. They add to the risk of developing HCC to a far lesser degree.
Birth control pills – Types of by word of mouth contraceptives used in the past was linked to some varieties of liver cancer, but infrequently to HCC. Most of these types of oral contraceptives are no longer available, and it is unknown if those now in use increase risk for HCC.
Anabolic steroids – Long-term steroid use can a little increase the risk for liver tumor.
Arsenic – In some parts of the world, drinking water contaminated with arsenic causes increased risk for developing liver malignancy.
Treatment of liver cancer
The treatment of liver malignancy is overall condition of the patient. First action if liver tumor is Chemotherapy. Chemotherapy is a powerful drug to kill cancer cells. Chemotherapy is a not effective not some cases of liver malignancy but type of chemotherapy is known as chemoembolization is an central part of treatment for HCC. Chemoembolization causes many of the same side special effects as other forms of chemotherapy, as well as abdominal pain, nausea and sickness. Second treatment is surgery.
Surgery is best treatment for local resectable tumor is usually an operation known as surgical resection. In some cases, the area of the liver where the malignancy is found can be completely indifferent. Alcohol injection has been shown to improve survival in people with small hepatocellular tumors. It may also be used to help reduce symptoms in cases of metastatic liver cancer. The most common side effect is leaking of alcohol onto the liver or into the abdominal cavity.
