Cancer has become a major public health problem in China, seriously affecting the health of Chinese residents and the national economic and social development.
The National Cancer Center (NCC) also recently released the 2022 China Malignant Tumor Disease Burden (CRC) results, which are jointly calculated by the National Cancer Center and the International Agency for Research on Oncology (IARC), which are consistent with the GloboCAN 2022 data released by the IRC and released simultaneously. 
In 2022, the number of new cancer cases in China was 482470 thousand
The number of new cancer cases in 2022 is estimated to be:482.470,000 cases, of which 253 were males390,000 cases, 229 women080,000 cases. The age-standardized incidence rate (ASIR) is:201 per 100,000 people61 casesThe incidence of cancer in all parts of the age group is low in the age group of 0 34 years old, the incidence rate of cancer in the age group of 35 and 39 years increases sharply, and the age group of 80-84 years reaches a peak. The overall incidence in males is lower than that in females in the 25-54 age groupThe age group over 60 is higher than that of women。The most common cancers in China in 2022 are:Lung cancer（106.060,000 cases), followed byColorectal cancer（51.710,000 cases).Thyroid cancer（46.610,000 cases).Liver cancer（36.770,000 cases).Stomach cancer（35.870,000 cases), accounting for 57 percent of the total number of new cancer cases42%。
Fig. 1 Estimated age-specific incidence of all cancers in China in 2022In 2022, the number of new cancer deaths in China will be 257420,000! The number of cancer deaths in 2022 is estimated as:257.420,000 cases, of which 162 were males930,000 cases, 94 females490,000 cases. The age-standardized mortality rate (ASMR) is96 per 100,000 people47 casesand present the following characteristics: all cancer sitesBoth the crude mortality rate and age-standardized mortality rate were higher in males than in femalesThe mortality rate increases significantly after the 40-44 age group, peaking in the age group of 85 years and older. Men have a higher mortality rate than women in people over the age of 40. The top five cancer deaths were lung cancer, liver cancer, stomach cancer, colorectal cancer, and esophageal cancer, which together accounted for 67 percent of total cancer deaths5%。

General trends
The overall incidence is increasingFrom 2000 to 2018, the main increase was thyroid cancer, cervical cancer, uterine cancer, lung cancer, breast cancer in women, and thyroid, prostate cancer and colorectal cancer in men.
Overall mortality is decreasingFrom 2000 to 2018, the age-standardized mortality rate (ASMR) decreased by 13%, with a decrease of 12%, down 1. per year for women3%。

(d) Female mortality. SummaryIn 2022, the number of new cancer cases and deaths in China has increased** compared to previous years. The increase in the number of deaths is more due to the aging of the population.
Lung cancer is the leading cause of morbidity and mortality from malignant tumors in China, which may be attributed to the high rate of smoking. The top five malignant tumors were lung cancer, colorectal cancer, thyroid cancer, liver cancer, and gastric cancer, and the top five malignant tumors in death were lung cancer, liver cancer, gastric cancer, colorectal cancer, and esophageal cancer.
