Rates of Lung Cancer Rising Steeply in Smoggy Beijing

In 2002, for every 100,000 men living in Beijing, 49 had lung cancer. By 2010, that number had risen more than 50 percent, to 75. Women in China are less likely to smoke and so have lower rates of the disease. But among those living in Beijing, a similar sharp rise in lung cancer cases occurred over the last decade. In 2002, for every 100,000 women living in Beijing, 30 had lung cancer; by 2010, that number had also risen more than 50 percent, to 46.

Those figures come from the Beijing office of China’s Cancer Prevention and Control Center, which believes the steep rise in lung cancer occurrences can be linked to worsening air pollution in China’s capital city. Wang Ning, deputy director of the cancer center, told China Daily that lung cancer caused by smoking and cases caused by exposure to air pollution generally exhibit different characteristics. “The proportion of lung adenocarcinoma cases”—those associated with air pollution—“is increasing,” Wang said.
