There are more than 626000 new cases of liver cancer in the world every year, and nearly half of them occur in China. Due to the vague understanding of the pathogenic factors of liver cancer, many preventable and treatable liver diseases eventually develop into liver cancer irreversibly, and even some liver cancer that could have been detected in the early stage missed the best treatment time.

So, are hepatitis patients bound to get liver cancer? How to detect liver cancer early? How to effectively prevent liver cancer? Yang Tian, deputy director of hepatobiliary surgery in Oriental Hepatobiliary surgery Hospital, answers those things about liver cancer for everyone.

What are the high-risk groups for liver cancer?

Yang Tian: most of the liver cancer occurs in a specific population, which is what we call "the high-risk group of liver cancer". People who are prone to liver cancer include:

Patients with chronic hepatitis: epidemiological statistics show that the area where hepatitis B is prevalent is also an area with a high incidence of liver cancer, and people infected with chronic hepatitis B are 10.7 times more likely to develop liver cancer than those without a history of hepatitis. Hepatitis virus (including hepatitis B and C) is one of the main initiating factors of human liver cancer. If there are patients with liver cancer in their immediate family, the risk of the disease is greater.

Patients with liver cirrhosis: patients with alcoholic cirrhosis (alcoholism), schistosomiasis cirrhosis or other causes of liver cirrhosis have an increased incidence of liver cancer. If combined with hepatitis infection, there is an increased risk of cancer.

Dietary carcinogens pollution: long-term consumption of mildew contaminated food, food containing nitrite is also one of the important factors to promote liver cancer. Aflatoxins produced by moldy corn and peanuts are clearly carcinogenic substances. Eating a large amount of nitrite can be converted into nitrosamines in the body, which has a clear carcinogenic effect.

Other patients with chronic liver disease, such as autoimmune liver disease, primary biliary cirrhosis, non-alcoholic steatohepatitis and so on.

How to effectively prevent liver cancer?

Yang Tian: for patients with hepatitis B, quitting smoking and drinking is of great help to reduce the risk of liver cancer, but new threats are also emerging. The researchers found that obesity, diabetes, fatty liver caused by an unhealthy diet and a sedentary lifestyle were all risk factors for liver cancer.

It is recommended to eat more fruits and vegetables. Excessive intake of fat and carbohydrates significantly increased the risk of liver cancer in patients with hepatitis B and C. Increasing the intake of fruits, vegetables and dietary fiber can reduce the risk of liver cancer. A study from Italy found that hepatitis patients who ate fruit, milk / yogurt, white meat and eggs reduced the incidence of liver cancer by 50%.

Have some coffee. Excessive alcohol intake increases the risk of liver cancer with or without hepatitis, and researchers have found that coffee helps prevent liver cancer. A study involving multiple ethnic groups shows that drinking two or more cups of coffee a day can prevent liver cancer.

Stick to proper physical exercise. Exercise can reduce obesity and diabetes, thereby reducing the risk of liver cancer in patients with hepatitis B. In fact, many studies have shown that exercise may play a greater role in preventing liver cancer than a healthy diet. People who walk or exercise for 7 hours or more a week reduce liver cancer mortality by 70%, while for liver cancer patients, even three hours of exercise a week can help reduce inflammation and liver cancer mortality.

Some people can't wake up in the morning without a cup of coffee, while others choose to have a cup of tea to welcome the new day. But what are the advantages and disadvantages of drinking coffee and tea, and which one is more beneficial to us?

A new study lists the health benefits of coffee and tea, which can help reduce diabetes, heart disease and cancer and help prevent obesity.

Studies have shown that people who drink black tea four times a day for six weeks have significantly lower levels of the stress hormone cortisol. But if milk is added to the tea, it loses its anti-cancer effect.

In addition, there may be pesticide residues in tea, even organic tea, also contains a lot of tannic acid, which hinders the absorption of iron in the blood, leading to anemia.

The study also found that drinking too hot tea all the time increases the risk of esophageal cancer. Drinking green tea can reduce women's risk of developing esophageal cancer by about 60%. At the same time, although coffee is not as healthy as tea in people's impression, it also has many benefits. It can also reduce the risk of diabetes, help middle-aged men prevent gout, and reduce the risk of Alzheimer's disease and liver cirrhosis and liver cancer in men.

Scientists believe that the chemicals contained in coffee can be refined into pharmaceuticals to treat heart disease and insomnia. But one study shows that coffee can reduce blood flow to the heart and discolor teeth.

Drinking eight or more cups of coffee a day increases a woman's risk of stillbirth, a Danish study found.

Most of the above studies used black coffee with a small amount of fresh milk and sugar, rather than high-calorie coffee drinks sold in coffee shops.

Duane Mellor, an assistant professor of nutrition at the University of Nottingham in the UK, says coffee and tea are actually better choices than sugary drinks. But he added that some drinks that are high in sugar cannot be called qualified coffee at all. Like a latte with syrup, there is too much sugar, energy and fat.

In most cases, coffee is healthier. Because most tea drinkers drink black tea (black), there is no doubt that the natural compounds in coffee are particularly beneficial to the human body.

Drinking two large cups of coffee or 300 milliliters of coffee a day can improve your depression. Drinking coffee reduces the risk of Parkinson's disease-coffee drinkers have a six times lower risk of developing Parkinson's disease than non-coffee drinkers, and if the amount of coffee consumed increases from 4 ounces to 24 ounces a day, the risk of the disease is lower. Human studies on the chemical properties of coffee have found that a cup of coffee contains powerful antioxidants that can inhibit the aging of human cells. Oxidative damage is associated with diabetes, arthritis, cancer and many other health problems, while antioxidants help reduce the risk of certain diseases.

Coffee contains high levels of flavonoid antioxidants, which help protect people against cardiovascular disease by lowering LDL cholesterol, or "bad" cholesterol, so coffee can also prevent heart attacks and strokes.

Coffee is known to stimulate intestinal peristalsis and reduce the risk of digestive disorders-such as gallstones and cirrhosis. In particular, coffee has the effect of preventing colon and rectal cancer.

But if you drink green tea, that is, unfermented tea, then I have to say that green tea is a healthier drink-it is rich in flavonoid antioxidants. As soon as the tea is fermented, its flavonoid antioxidants are lost.

So, in short, drinking coffee can also prevent liver cancer!
