What causes liver cancer? How can liver cancer be prevented?

Liver cancer is a type of cancer with a high incidence rate in my country. Because its onset is relatively hidden and its symptoms are very similar to those of liver diseases such as hepatitis B and cirrhosis, liver cancer patients are often diagnosed in the late stage and are even called the "king of cancers." Therefore, early prevention and treatment of liver cancer has become a top priority. In order to prevent liver cancer more effectively, let's first understand the causes of liver cancer.

What is liver cancer?

1. Viral hepatitis and cirrhosis

Many clinical cases have proven that viral hepatitis, especially hepatitis B virus, less commonly hepatitis C virus, and cirrhosis are one of the major causes of liver cancer.

2. Aflatoxin

Data show that the prevalence of liver cancer may be related to aflatoxin contamination of food. Aflatoxin B1 is the strongest carcinogen for animal liver cancer.

2. Carcinogen pollution

For example, drinking water, many areas drink ditch and pond water, and ditch and pond water contains something called blue-green algae, which produces a toxin called algae toxin. After experiments, they are all carcinogenic substances, and their carcinogenicity is very high.

4. Genetic factors

If someone in the family has a history of liver cancer, then the chances of family members getting liver cancer will be higher. This may be related to genetics or vertical transmission of the hepatitis virus.

5. Other possible carcinogens

Alcohol, pesticides such as organochlorines, liver flukes, trace elements such as excessive copper and zinc, and molybdenum deficiency, etc.

What should we pay attention to in preventing liver cancer?

1. Hepatitis B vaccine injection

Hepatitis can easily develop into liver cancer, and my country is a country with a high incidence of hepatitis B. Currently, there is no particularly effective way to prevent hepatitis B, so the most direct and effective way to prevent hepatitis B is to get vaccinated. It is recommended that adults and children should get vaccinated. In addition, attention should be paid to hygiene.

2. Do not eat moldy food

Moldy food contains a large amount of aflatoxin, which is a strong carcinogen, so its consumption must be prohibited. Generally, moldy peanuts, corn, etc. contain relatively high levels of aflatoxin.

3. Good lifestyle

Try to avoid smoking and drinking, especially alcohol, which is very harmful to the liver, easily leading to alcoholic hepatitis, reducing a person's immune ability, and affecting the liver's detoxification function.

4. Regular inspection

Since liver cancer is very common in my country, the best way to effectively prevent liver cancer is to have regular physical examinations, especially for people at high risk of liver cancer, such as those with a family history, or those who drink alcohol for a long time and have alcoholism, or those with diabetes, hepatitis B, hepatitis and other diseases. It is generally recommended to have a physical examination once a year, and B-ultrasound is a good choice, which can detect early liver cancer.
