Global Cancer Report 2014: China ranks first in the world in terms of new cases and deaths, with a lower incidence rate than developed countries World Cancer Day is celebrated on February 4 every year, and the World Health Organization (WHO) released the Global Cancer Report 2014 on February 3, which says that the number of cancer patients and deaths worldwide increased disturbingly in 2012. Nearly half of all new cancer cases occurred in Asia, most of them in China, which ranked first in new cancer cases. China led the world in new cases and deaths for four types of malignancies, including liver, esophageal, stomach and lung. Despite this, China did not rank among the countries with the highest cancer incidence and mortality rates in 2012. China’s lung cancer rate is actually lower than most European countries, despite high smoking rates and declining air quality. The latest edition of the World Cancer Report, compiled by the International Agency for Research on Cancer (IARC), the official cancer agency of the WHO, with the participation of more than 250 scientists from more than 40 countries, provides a comprehensive picture of the overall situation and prevalence of 28 types of cancer in more than 180 countries worldwide. This is the first report in six years to provide an overview of the global cancer situation. The report predicts a rapid increase in the number of cancer cases worldwide, from 14 million in 2012 to 19 million by 2025 and 24 million by 2035. The report also shows that developing countries in Africa, Asia and Central and South America have the most serious cancer incidence situation. 14 million new cancer cases and 8.2 million deaths were recorded worldwide in 2012. Among them, China added 3.07 million new cancer cases and caused about 2.2 million deaths, accounting for 21.9 percent and 26.8 percent of the global total, respectively. The WHO figures are slightly lower than China’s own statistics. Data released by the National Tumor Registry for 2012 show that China has about 3.5 million new cancer cases each year, resulting in about 2.5 million deaths. The overall impact of cancer will “undoubtedly” hit developing countries the hardest, said Ms. Margaret Chan, director general of the WHO. As more and more people in developing countries improve their standard of living and change their diets, their chances of getting cancer increase dramatically.

Huge population base makes China number one in cancer deaths Although it is always said that China has serious pollution due to haze, Europe and America still have the highest cancer rates. In the report, China did not enter the ranks of countries with the highest cancer rates in 2012, and the top 5 countries were Denmark, France, Australia, Belgium and Norway. China is also not the country with the highest cancer mortality rate. According to the statistics, the top ranked countries are Mongolia, Hungary, Armenia, Serbia and Uruguay. According to National Public Radio (NPR), cancer rates in developed countries are still higher than those in developing countries. Residents of North American and European countries are most likely to contract cancer, but China’s large population base makes it the country with the highest number of cancer deaths in the world. China actually has a lower rate of lung cancer than the vast majority of European countries, despite high smoking rates. So which cancer rate is the world leader in China? Stomach cancer and liver cancer. However, China’s rectal cancer rate is similar to Japan’s slightly higher, the world’s first and second rectal cancer is New Zealand and the United States. In addition, it is said that Japan eats healthier than China, but the death rate of stomach cancer in Japan is also the first of all cancers. Despite the increasing severity of cancer in developing countries, the world’s most vulnerable population is still black Americans. 2. Lung cancer is the deadliest in the world Lung cancer is still the most common and deadliest cancer, with about 1.8 million new patients and 1.59 million deaths in 2012. China accounted for more than 1/3 of such cases. Experts say that smoking, long-term exposure to air pollution and occupational exposure to carcinogens are the main factors that increase the risk of lung cancer (in China). Among other types of cancer, China accounts for about half of the world’s new liver cancer and esophageal cancer patients, and 51% and 49% of the world’s deaths, respectively, and more than 40% of the world’s new stomach cancer cases and related deaths in 2012. 3.Experts: China has the most cancer deaths, accounting for about half of the world According to land media reports, the 22nd Asia-Pacific Cancer Conference held in Tianjin recently issued an announcement that China accounts for more than 20 percent of the new cancer cases each year, and the total number of deaths from eight types of cancer accounts for more than 80 percent of the total number of cancer deaths in China, namely lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer, cervical cancer, breast cancer and nasopharyngeal cancer. breast cancer and nasopharyngeal cancer. According to Hao Xishan, an academician of the Chinese Academy of Engineering, the Asia-Pacific region accounts for 45% of the new cancer cases and about half of the global cancer deaths. The three most common cancers in Asian countries are lung cancer, stomach cancer and liver cancer, of which lung cancer is the most deadly disease. According to Yang Gonghuan, former deputy director of the Chinese Center for Disease Control and Prevention, cancer has become the number one cause of death among the Chinese population and is at a high level in the world, and there are more and more young people suffering from the disease. Some experts expect that the total number of new cancer cases in China will reach about 4 million by 2020, and the total number of cases will reach 6 million each year. 4.Statistical results: over 2 million deaths per year Lung cancer causes the most deaths According to the 2012 China Tumor Registry Annual Report released by China Tumor Registry in early 2013, there are about 3.12 million new cancer cases and over 2 million deaths per year in China, 6 people are diagnosed with cancer every minute, 8,550 people become cancer patients every day, and one out of every 7 to 8 people dies due to cancer. Lung cancer, stomach cancer, rectal cancer, liver cancer and esophageal cancer are the most common cancers in China, while breast cancer, colorectal cancer and other cancers are also on the rise. Lung cancer is the most deadly cancer type. According to the results of the third survey on the causes of death in China, the mortality rate of lung cancer has increased by 465% in the past 30 years, replacing liver cancer as the most deadly malignant tumor in China and ranking first in the data of cancer deaths. 5.Officially, it is the first time to admit that “cancer village” is related to water pollution Water pollution can lead to high incidence of cancer, which has been admitted by Chinese officials. At present, there are many “cancer villages” around China, most of them are caused by the pollution of water sources. More than half of China’s rivers and lakes have been seriously polluted and turned into “toxic water” due to the pollution of water sources by chemical industry waste, and “cancer villages” have appeared in many places. According to the “Map of Cancer Villages in China” produced by a public service figure, there are 247 cancer villages in China, and if unofficial data is included, there are as many as 459 “cancer villages” on the mainland. In February 2013, China’s Ministry of Environmental Protection released the 12th Five-Year Plan for the Prevention and Control of Chemical Environmental Risks, which acknowledged the existence of “cancer villages” for the first time. According to Yang Gonghuan, relevant studies have initially found that water pollution and tumors are correlated, i.e. the emergence of “cancer villages” is related to water pollution. At present, there are 259 officially recognized cancer villages in China, most of which are related to the pollution of nearby rivers and water sources by high pollution enterprises. China has detected many kinds of chemical substances in water, wildlife and human body, some of which are in concentrations higher than international standards, resulting in a number of sudden water and air pollution incidents, and even the emergence of “cancer villages” under the harsh environment, thousands of new chemical substances of unknown toxicity are still declared for production or import in China every year, resulting in more serious environmental pollution. In addition, 90 percent of China’s urban underground water sources are polluted. In addition, 90 percent of China’s urban groundwater sources are contaminated. Ma Jun, director of the Chinese Communist Party’s Center for Public Environmental Studies, once noted that it would take 1,000 years to clean up groundwater pollution that has penetrated deep into the ground. The Hopkins University School of Public Health reported six years ago that more than 3/4 of China’s 50,000 kilometers of major rivers are no longer viable for fish. 6. Experts from various countries: China’s cancer rise Environmental pollution is the main cause Zeng Jun, chief physician of the respiratory department of the First People’s Hospital of Guangzhou, believes that the increasingly severe hazy weather and air pollution in mainland China is also a major cause of the increase in lung cancer. At present, the incidence of lung cancer in China has increased significantly and become a major disease, mainly due to air pollution. The problem of environmental pollution in China has become so prominent that hazy weather is seen in every city and is affecting human survival all the time. Li Feng, a researcher of a pharmaceutical company in the United States, also believes that environmental pollution is the main reason for the rising incidence of cancer in China. The head of the U.S.-China Association for Science, Technology and Cultural Exchange in New York, Mr. Xie Jia Ye, believes that the high incidence of cancer in China in recent years is the result of the combined effects of decades of economic development on the environment, demographics and lifestyles. However, there are reports that some of the toxic chemicals that have been phased out or restricted in developed countries are still being produced and used on a large scale in China. More than 3,000 of them are bioaccumulative, non-degradable, carcinogenic and teratogenic chemicals.
