Epidemiological characteristics of liver cancer

The epidemiological characteristics of liver cancer mainly include the distribution patterns of liver cancer patients and influencing factors, which can be used to explore the causes, clarify the epidemic patterns, and formulate countermeasures and measures to prevent, control and eliminate the disease, which is of great significance for preventing the occurrence of liver cancer.

Understanding the regional, population, and time distribution of liver cancer cases in my country will help in targeted prevention and treatment of liver cancer.

Regional distribution

In my country, liver cancer is mainly prevalent in the southeastern coastal areas, such as Jiangsu, Fujian, Guangdong and Guangxi. The mortality rate is highest in Shanghai, Fujian, Jiangsu, Guangzhou and Zhejiang. The mortality rate of male liver cancer is over 40/100,000, while the mortality rate in low-incidence areas is less than 3/100,000, such as Yunnan, Guizhou, Gansu and Xinjiang. It can be seen that the regional distribution of liver cancer is very uneven, and there is no obvious pattern.

Distribution of two groups

In terms of age, liver cancer occurs in infants as young as 2 months old to people as old as 80 years old. And from the statistical results, in places with high mortality rates, the age of onset and peak incidence tends to be younger, while in areas with low mortality rates, the age of the deceased tends to be older.

Three time distribution

In recent years, the incidence and mortality rates of liver cancer have been slowly increasing.
