The Global Cancer Report 2014 published by the World Health Organization shows that China ranks first in the world in terms of new cancer cases, with liver cancer ranking first in the world in terms of new cases and deaths. Currently, the incidence rate of liver cancer in China is about 25.7/100,000, making it the third most common malignant tumor after stomach cancer and lung cancer in terms of mortality. The high incidence age of liver cancer is after 40 years old, with middle-aged and elderly people being the majority, and 50-60 years old is the high incidence age group. The number of male patients suffering from liver cancer is significantly more than that of female, generally speaking, the number of male liver cancer is 7-10 times that of female. Studies have shown that 85%-90% of liver cancers are clinically related to hepatitis B. However, it is worrying that at present, 7.18% of the total population in China are carriers of hepatitis B virus. With the development of modern medicine, liver cancer can be detected early and the cure rate can be over 80%. Therefore, high-risk groups must have regular checkups and seek medical treatment in time when symptoms are detected. Early symptoms of liver cancer are usually hidden, and many patients have almost no symptoms in the early stage, and once they have obvious symptoms of liver cancer, they are already in the middle and late stage. Therefore, good prevention of liver cancer can effectively reduce the mortality rate of liver cancer patients and greatly improve the survival time of patients. Compared with middle-aged and elderly people, young people have less initiative to have regular physical checkups, so they are at greater risk of developing liver cancer. In this regard, experts point out that it is more important to prevent liver cancer and let the public know the specific ways of liver cancer screening.
