Who is at risk for Liver (Hepatocellular) Cancer? ?
Being infected with certain types of the hepatitis virus can cause hepatitis and increase the risk of liver cancer.
                    Hepatitis is most commonly caused by the hepatitis virus. Hepatitis is a disease that causes inflammation (swelling) of the liver. Damage to the liver from hepatitis that lasts a long time can increase the risk of liver cancer.    There are six types of the hepatitis virus. Hepatitis A (HAV), hepatitis B (HBV), and hepatitis C (HCV) are the three most common types. These three viruses cause similar symptoms, but the ways they spread and affect the liver are different.    The Hepatitis A vaccine and the hepatitis B vaccine prevent infection with hepatitis A and hepatitis B. There is no vaccine to prevent infection with hepatitis C. If a person has had one type of hepatitis in the past, it is still possible to get the other types.   Hepatitis viruses include:     Hepatitis A    Hepatitis A is caused by eating food or drinking water infected with hepatitis A virus. It does not lead to chronic disease. People with hepatitis A usually get better without treatment.       Hepatitis B    Hepatitis B is caused by contact with the blood, semen, or other body fluid of a person infected with hepatitis B virus. It is a serious infection that may become chronic and cause scarring of the liver (cirrhosis). This may lead to liver cancer. Blood banks test all donated blood for hepatitis B, which greatly lowers the risk of getting the virus from blood transfusions.       Hepatitis C    Hepatitis C is caused by contact with the blood of a person infected with hepatitis C virus. Hepatitis C may range from a mild illness that lasts a few weeks to a serious, lifelong illness. Most people who have hepatitis C develop a chronic infection that may cause scarring of the liver (cirrhosis). This may lead to liver cancer. Blood banks test all donated blood for hepatitis C, which greatly lowers the risk of getting the virus from blood transfusions.       Hepatitis D    Hepatitis D develops in people already infected with hepatitis B. It is caused by hepatitis D virus (HDV) and is spread through contact with infected blood or dirty needles, or by having unprotected sex with a person infected with HDV. Hepatitis D causes acute hepatitis.       Hepatitis E    Hepatitis E is caused by hepatitis E virus (HEV). Hepatitis E can be spread through oral- anal contact or by drinking infected water. Hepatitis E is rare in the United States.       Hepatitis G    Being infected with hepatitis G virus (HGV) has not been shown to cause liver cancer.
               
               
                    Key Points
                    - Avoiding risk factors and increasing protective factors may help prevent cancer.    - The following risk factors may increase the risk of liver cancer:         - Hepatitis B and C     - Cirrhosis     - Aflatoxin        - The following protective factor may decrease the risk of liver cancer:         - Hepatitis B vaccine        - Cancer prevention clinical trials are used to study ways to prevent cancer.     - New ways to prevent liver cancer are being studied in clinical trials.
                
                
                    Avoiding risk factors and increasing protective factors may help prevent cancer.
                    Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer.
                
                
                    The following risk factors may increase the risk of liver cancer:
                    Hepatitis B and C    Having chronic hepatitis B or chronic hepatitis C increases the risk of developing liver cancer. The risk is even greater for people with both hepatitis B and C. Also, the longer the hepatitis infection lasts (especially hepatitis C), the greater the risk.    In a study of patients with chronic hepatitis C, those who were treated to lower their iron levels by having blood drawn and eating a low-iron diet were less likely to develop liver cancer than those who did not have this treatment.       Cirrhosis    The risk of developing liver cancer is increased for people who have cirrhosis, a disease in which healthy liver tissue is replaced by scar tissue. The scar tissue blocks the flow of blood through the liver and keeps it from working as it should. Chronic alcoholism and chronic hepatitis C are the most common causes of cirrhosis.       Aflatoxin    The risk of developing liver cancer may be increased by eating foods that contain aflatoxin (poison from a fungus that can grow on foods, such as grains and nuts, that have not been stored properly). + CancerGov + Liver (Hepatocellular) Cancer
