Who are the high-risk groups for liver cancer? Eating this kind of food for a long time may cause liver cancer

Long-term consumption of moldy, seaweed-contaminated, or aflatoxin- or nitrosamine-rich foods may cause liver cancer. Especially for chronic hepatitis B carriers, long-term heavy drinking can also increase the risk of liver cancer. Therefore, the majority of people at high risk of liver cancer, such as hepatitis and cirrhosis, need to undergo a physical examination every six months for early diagnosis, while liver cancer patients can improve the cure rate and prolong survival through the multidisciplinary collaborative diagnosis and treatment model (MDT) of "individualized treatment" and "comprehensive treatment".

According to statistics, about 500,000 people die of liver cancer every year in the world, and 50% to 55% of them are in my country. It ranks second in cancer mortality among urban populations and third in rural areas. Globally, the 5-year survival rate of liver cancer is only 36%, and the recurrence rate is also very high, with about 50% to 60% of patients recurring within one to two years after surgery.

Liver cancer is closely related to hepatitis and cirrhosis. The three are in a "progressive relationship". my country is a high-incidence area of ​​hepatitis B in the world. After patients are infected with the hepatitis B virus through blood, mother-to-child transmission and sexual transmission, liver cells begin to degenerate and necrotize, and then the liver proliferates to form nodules, which is commonly known as cirrhosis. In this way, some cells will become cancerous. Experts say that patients with hepatitis and cirrhosis are ten times more likely to develop liver cancer than ordinary people.

"Patients with liver cancer usually do not have any clinical symptoms in the early stage, and the early detection rate is less than 15%." Experts say that since liver cancer tumors grow very fast, once patients experience perceptible clinical symptoms such as abdominal pain, fatigue, weight loss, shoulder pain, jaundice, ascites, etc., they are often in the middle and late stages. Therefore, people at high risk of liver cancer, including those with hepatitis B, hepatitis C and cirrhosis, must insist on undergoing liver color Doppler ultrasound and alpha-fetoprotein (AFp) testing every six months. If the lesion is discovered early, the treatment effect and long-term survival rate can be significantly improved, and there are many more treatment options.

Who are the high-risk groups for liver cancer?

Liver cancer patients must pay attention to treatment, especially those with early liver cancer. Once diagnosed, they need to receive timely treatment to avoid further deterioration of liver cancer. Liver cancer is so harmful that it is very important to prevent it, especially for people with a high risk of liver cancer. So, which groups of people are most likely to develop liver cancer?

1. People who take in too much nitrosamine compounds. Dimethylnitrosamine has been isolated from the food of residents in South Africa, a high-risk area for liver cancer. Such compounds can also cause other tumors such as esophageal cancer. Therefore, nitrosamine compounds are also classified as one of the causes of liver cancer.

2. People with a family history of liver cancer. On the one hand, many hereditary diseases that damage the liver, such as pigmentation disease and glycogen storage disease, will develop into cirrhosis, and the incidence of liver cancer is also very high; on the other hand, it is believed that the familial clustering of liver cancer is mainly caused by the clustering of hepatitis B virus. There is currently no evidence that liver cancer can be inherited.

3. People who eat food contaminated by Aspergillus flavus. Many years ago, a farm in the UK fed turkeys with peanut cake that was moldy due to Aspergillus flavus, causing 100,000 chicks to die quickly. Epidemiological studies have shown that the geographical distribution of liver cancer in my country is basically consistent with the distribution of Aspergillus flavus contamination.

4. People who drink alcohol for a long time. Long-term alcoholism can significantly damage liver cells and lead to malnutrition, making the liver prone to cirrhosis, which can develop into liver cancer. Of course, in addition to the above-mentioned dietary factors, hepatitis B, parasitic diseases in the liver (such as Clonorchis sinensis), and genetic susceptibility are also closely related to the occurrence of liver cancer.

5. People living in areas with a high incidence of liver cancer. The areas with a high incidence of liver cancer in China are mainly in the southeastern coastal areas, such as Fusui and Longan in Guangxi, Xiamen and Tongan in Fujian, Qidong and Haimen in Jiangsu, Chongming and Nanhui in Shanghai, etc. In these areas, at least 30 people die of liver cancer per 100,000 people. In addition, the incidence of liver cancer is higher in coastal areas than in inland areas, and higher in southeastern and northeastern areas than in southwest and northwest areas.

6. Patients with post-hepatitis cirrhosis. The above cirrhosis patients develop cancer, and most of them have recurrent illness, poor improvement of liver function, and frequent complications such as ascites.
