National Cancer Registration Center: lung cancer and breast cancer rank first in malignant tumors of men and women in China

Source: health / Li Zijun June 5, 2015, the first county cancer conference was held in Beijing Chen Wanqing, deputy director of the National Cancer Prevention and research office and the National Cancer Registration Center, introduced the top ten malignant tumors in China According to the statistics, lung cancer and breast cancer are the most common malignant tumors in China China is not a "big cancer country" Some people think that with the rapid economic development, China has become a "big cancer country" Chen Wanqing does not agree with this view Chen Wanqing said that at present, the annual incidence of new cancer cases worldwide is 14 million 90 thousand, and China's patients occupy 1/4 to 1/3 of the total number of patients The incidence rate is similar to that of the population Globally, the incidence rate of cancer in China is below average Last year, there were about 8.2 million cancer deaths worldwide, of which China accounted for 27% "To be sure, the increasing number of cancer patients has increased the cancer burden all over the world." Chen Wanqing said In order to make a comprehensive statistics of the incidence of malignant tumors in the country, China has set up cancer registries Last year, there were 308 cancer registries nationwide, which increased to 410 at the beginning of this year On the whole, most of China's cancer registries in the past were in the East, but now they are increasing in the West According to the data registered in the cancer registration center, in 2014, the total number of new cancer cases in China was 3.372 million, with 1.1919 million men and 1.453 million women, slightly fewer than men At the meeting, Chen Wanqing announced the composition of the top ten malignant tumors in China Lung cancer ranked first in male patients, accounting for 23.01% of the total number of cancers, followed by gastric cancer, liver cancer, esophageal cancer and colon cancer, which accounted for half of the incidence of male cancer, followed by bladder cancer, prostate cancer, pancreatic cancer, brain cancer and lymph cancer 17.10% of female patients with malignant tumors had breast cancer, followed by lung cancer, colorectal cancer, gastric cancer and liver cancer, cervical cancer, esophageal cancer, thyroid cancer, uterine cancer and ovarian cancer The incidence rate of cancer in different city areas is changing Chen Wanqing said that the incidence of cancer in urban and rural areas is changing Incidence rate incidence rate of lung cancer in city is higher than that in rural area In the past, the incidence of lung cancer in city was only half that in city But now the incidence of lung cancer in urban and rural areas is very close Chen Wanqing predicted the trend of cancer incidence in China in the future He said the overall incidence rate of cancer will increase slowly, which stems from the change in the age structure of the population Because of the high correlation between cancer and age, with the aging of society, the total death cause of cancer will reach 1/4 Comparison of five-year survival rate of cancer patients in China and the United States: China is only half of the United States today, many cancer patients choose to receive treatment in the United States From the perspective of five-year survival rate of cancer patients in China and the United States, this choice is not unreasonable Since the early 1990s, cancer mortality has declined, but it has increased slightly in China The survival rate of Chinese women is slightly higher than that of men The survival rate of lung cancer was 16.1% in China, 17% in the United States, 27% in China and 28% in the United States, 20.9% in China and 19% in the United States It can be seen that there is no significant difference in survival rate between China and the United States in these cancers with poor prognosis However, the difference of survival rate between the two countries is obvious The survival rate of prostate cancer patients in China is 53.8%; that in the United States is 100%; that in leukemia patients in China is 19.6%, and that in the United States is as high as 58% In fact, the survival rate of cancer patients with better prognosis can be greatly improved if they are found and treated early The statistical results show that the cancer survival rate of China in the top ten is 30.9%, and that of the United States is 68% Obviously, China is less than half of the United States Chen Wanqing said that China's cancer treatment level is uneven, resulting in poor treatment level, which indicates that there is still a lot of room for improvement in the prevention and treatment of some cancers in China.
