[Hello, 헬스]Liver cancer? The main cause is the hepatitis B virus

Often, alcohol is the cause of liver cancer. However, liver cancer is not the leading cause of hepatitis B virus.

According to data published by the Korean Society of Cancer of Liver in 2014, 72% of patients with hepatoma were affected by the hepatitis B virus and 12% by the hepatitis C virus. The direct cause of alcohol was only 9%.

Most carriers of hepatitis B virus are infected when they are born from a mother who has a virus. If they are not handled correctly from childhood, they will develop chronic hepatitis or liver cirrhosis (cirrhosis) and will develop liver cancer.

When the hepatitis B virus enters the body, the body's immune system attacks hepatocytes infected by the virus and hepatocytes continue to be damaged. Hepatocytes are replaced by abnormal fibrous tissue instead of new healthy cells. It becomes fibrotic and turns into cirrhosis and develops in liver cancer.

Therefore, hepatitis B holders must be examined regularly and consistently with antiviral drugs to prevent the progression of liver fibrosis.

In the case of hepatitis C, preventive vaccines have not yet developed and the incidence of infection is relatively high due to lack of publicity on the transmission route.

Hepatitis C extends through the blood, and the recent sharing of needles (drug addicts) has been reported as an important causative pathway. In addition, unhygienic acupuncture·Piercing·Tattoo·There is a risk of infection, even if there are four or more people and sexual activity.

Hepatitis C is mostly uninfected in the early stages of the infection, and even if chronic hepatitis is present,·Indigestion·There are no special symptoms besides superior abdominal discomfort. About three-quarters of the patients develop chronic hepatitis after acute hepatitis C, and about 20-30% of chronic patients with hepatitis C develop cirrhosis. Patients who progress to cirrhosis are more likely to develop liver cancer than cirrhosis due to hepatitis B virus.

Although the therapeutic effect varies depending on the type of hepatitis C virus (genotype), the efficacy of the new oral anti-viral drug has been improved by 50-80% since the beginning of 2000.

Recently, non-alcoholic fatty liver is emerging as a cause of liver disease and liver cancer. This is because the antiviral agent that can manage hepatitis B and C develops and the obesity population is increasing due to westernization of Korean eating habits.

According to data from the National Health Insurance Review Agency, patients with alcoholic liver disease decreased 22% from 43,344 in 2011 to 33,903 in 2015, while non-helical fatty patients increased from 13,429 in 2011 to 28,865 in 2015 Increased 115%.

Non-alcoholic fatty liver is a simple fatty liver that occurs mainly in the liver, but in some cases, non-alcoholic fatty liver hepatitis and inflammatory symptoms due to hepatocyte necrosis do not occur. The disease of the non-alcoholic fatty liver may progress in liver cirrhosis or liver cancer in 10 ~ 15% and the risk of having liver cancer is two times greater than the normal weight in obesity.

"Often the case that hepatocellular carcinoma is caused by excessive alcohol use, so the patient often has hepatitis virus or neglects the fact that it is a high-risk liver cancer due to the non-alcoholic fatty liver, "Although you do not drink well, you should check your own hepatitis and fatty liver with medical control," he said.
