What foods should you eat more to prevent liver cancer? Doing these things can easily prevent liver cancer

"Liver cancer has no symptoms in its early stages, and it is too late to seek medical treatment after symptoms appear, so early detection is the only way to achieve better treatment results," said an expert. The development of modern medical diagnostic methods, especially imaging technology, has enabled more early liver cancers to be discovered, improving the overall cure rate of liver cancer patients.

According to the "Expert Consensus on Standardized Diagnosis and Treatment of Primary Liver Cancer" and the Ministry of Health's "Guidelines for the Diagnosis and Treatment of Primary Liver Cancer", high-risk groups for liver cancer include: HBV, HCV infected people, cirrhosis caused by various reasons, long-term alcoholics and those with a family history of liver cancer. After the age of 35-40, such people should undergo serum alpha-fetoprotein (AFp) testing and liver ultrasound examination every 6 months. Once elevated AFp or "space-occupying lesions" in the liver area are found, more accurate CT and MRI examinations should be used.

Of course, many people worry that it is liver cancer after finding liver nodules during physical examinations. In fact, in the absence of hepatitis virus infection, most liver nodules are benign lesions, such as hemangiomas, focal nodular hyperplasia, etc. These benign lesions will not become cancerous, but it is important to be careful not to misdiagnose liver cancer as other benign lesions, and benign liver nodules should also be checked regularly.

Radical treatment for early-stage liver cancer

For early liver cancer, radical treatment methods should be chosen, including surgical resection, liver transplantation, ablation and other methods. Currently, the 5-year survival rate of early liver cancer after treatment is 50-70%. How to select the most suitable treatment method for early liver cancer patients through multidisciplinary comprehensive treatment methods, prolong survival time and improve quality of life is the most concerned issue for clinicians.

Experts believe that in clinical practice, appropriate initial treatment should be selected based on comprehensive considerations such as the patient's liver function, tumor size, number, location, technical strength of each medical unit, and patient willingness. Resection is the first choice for patients who can tolerate surgery. For single liver cancer located deep in the liver with a diameter of less than 2 cm, local ablation therapy can achieve similar results to surgical resection. Liver transplantation is suitable for patients with poor liver function.

Prevent liver cancer: control viral infections, limit alcohol, and improve lifestyle habits.

More than two thousand years ago, my country's "Huangdi Neijing" proposed that "the best doctor treats the disease before it occurs, the middle doctor treats the disease before it occurs, and the worst doctor treats the disease after it occurs." The first level of prevention among the three levels of liver cancer prevention is to prevent various liver cancer susceptibility factors.

Experts believe: "Although the cause of liver cancer is not yet fully understood, it has been proven to be closely related to hepatitis virus infection, long-term heavy drinking, environmental and dietary factors." Therefore, prevention of liver cancer must start with avoiding these high-risk factors.

First, control viral infection and progression:

There are more than 90 million people infected with hepatitis B virus (HBV) and about 40 million people infected with hepatitis C virus (HCV) in my country. Epidemiological results show that areas with high hepatitis B infection rates are also high-incidence areas for liver cancer, such as the southeastern coastal areas, where hepatitis B virus is more closely related to liver cancer. After a person is infected with hepatitis B virus, the virus replicates and becomes active in the body, causing damage to the liver. Long-term damage like this leads to cirrhosis of the liver, which in turn causes liver cancer.

To this end, my country has included hepatitis B vaccine as part of the children's immunization program to prevent hepatitis B, which, to a certain extent, also prevents liver cancer. For those who have been infected with the hepatitis B virus and are in chronic hepatitis, appropriate antiviral treatment can also reduce the occurrence of liver cancer.

Second, limit alcohol

Recently, it has been discovered that alcohol-induced fatty liver can also lead to liver cancer. This is because the ethanol in the wine needs to be metabolized by the liver to complete the process of converting ethanol into carbon dioxide and water. The intermediate product of ethanol metabolism, acetaldehyde, has a direct toxic effect on liver cells. At the same time, ethanol metabolism also interferes with the metabolic processes of various substances in the body, such as fat metabolism and hormone metabolism. These processes not only destroy liver cells and cause liver damage, but also increase the burden on liver detoxification and metabolism, leading to fatty lesions in liver cells, and ultimately leading to alcoholic fatty liver, alcoholic hepatitis and alcoholic cirrhosis. In addition, studies have shown that alcohol is a clear carcinogenic factor in patients infected with hepatitis B.

Experts stressed: "If hepatitis patients continue to drink a lot, it will promote the occurrence and progression of liver cancer, especially those who are long-term alcoholics. In particular, we advise chronic hepatitis B patients not to continue drinking. The hepatitis virus and alcohol damage will cause the liver to go on strike sooner or later."

Third, improve your living habits

Unclean drinking water, long-term consumption of moldy and nitrosamine-containing foods, and poor hygiene conditions are also important factors that promote liver cancer. Why should we not eat moldy food? Moldy food contains aflatoxin, which can cause liver cancer. Various studies have shown that aflatoxin is the strongest chemical carcinogen. In terms of its ability to induce liver cancer, it is about 75 times more carcinogenic than the known dimethylnitrosamine. Among them, aflatoxin B is the most carcinogenic, and aflatoxin B1 is closely related to liver cancer.

Aflatoxins, especially aflatoxin B1, can produce an epoxide after being metabolized in the liver. After binding to human DNA molecules, it can change the properties of DNA replication templates, interfere with DNA transcription, and ultimately lead to cell carcinogenesis.

To this end, you can completely stay away from tumors by not eating moldy food, actively treating fatty liver, eating regularly and healthily, exercising appropriately, and improving the body's resistance.

What foods can prevent liver cancer?

Over the past half century, domestic and foreign scholars have conducted extensive and in-depth research on the causes of liver cancer. At present, the risk factors for liver cancer in my country are as follows: viral hepatitis, eating food contaminated by aflatoxin and its mycotoxin, chemical carcinogens, water pollution, drinking, etc. In addition, disease factors, genetic factors and nutritional factors also have an impact. Studies have found that the intake of vegetables and fruits can reduce the risk of cancer. The following foods can effectively prevent liver cancer.

1. Carrots and citrus

The protective effect of vegetables and fruits on the liver is produced by the interaction between the vitamins, minerals, fibers, etc. in them. Green leafy vegetables, carrots, potatoes and citrus fruits have the strongest preventive effect. Dr. Dong Jing recommends eating five or more kinds of vegetables and fruits every day, including a glass of juice in the morning, a piece of fruit in the morning and afternoon, and two or more servings of vegetables at dinner. The total daily intake is about 400-800 grams, which can reduce your risk of liver cancer by 20%.

2. Tieguanyin

People in southern Fujian love to drink tea. Dr. Dong said that it is very beneficial for preventing liver cancer. Tieguanyin, which is common in southern Fujian, is the best, and Longjing before the rain is also good.

3. Dairy products

Medical research has shown that if you consume dairy products, including milk and yogurt, every day while controlling your alcohol intake, your risk of liver cancer will be reduced by 78%. Currently, children have developed the habit of consuming dairy products, but only a few adults do, so this may be improved.

4. "Three Bamboo Shoots"

The three shoots are bamboo shoots, lettuce and asparagus. Experts suggest that eating more of these three foods on a daily basis can reduce the incidence of liver cancer, and they are also delicious.
