With increasing mortality, cancer is the leading cause of death in China. The prevalence of cancer in China is linked to air pollution.

Cancer related deaths and cases are increasing alarmingly in China, according to new study.

In 2015, a total of 2.8 million people died of cancer in China while 4.3 million new cases have been reported and lung cancer has emerged as the most common of all cancer cases.

“Cancer incidence and mortality have been increasing in China, making cancer the leading cause of death since 2010 and a major public health problem in the country.” Study reads.

China represents almost one-fifth of the total population of the world with 1.37 billion people residing in the country. Previous studies related to cancer were limited to just a small sample of the population. Thus, they could not reflect the actual prevalence of the disease.

For the latest research, a combined team of researchers from the American Cancer Society, University of Sydney, and National Cancer Center Beijing used the most recent mortality data compiled by 72 local cancer registries and found that the cancer rate is alarmingly high. Lung cancer was the most common cancer while other fairly common cancers diagnosed in China were stomach, liver and esophageal cancer. Mortality rate for all cancer cases combined was significantly higher in men than in women and in rural area than in urban areas.

Based on current data, researchers estimated 4.3 million new diagnosed cases in China and 2.8 million deaths from cancer in 2015, or about 7,500 deaths, on average, per day. Around 12,000 people have been diagnosed with cancer each day.

“Almost 22% of global new cancer cases and close to 27% of global cancer deaths occur in China.” Authors wrote in the study.

Study blames air pollution for this unusual rise in lung cancer related cases and also mortality rate.

“Outdoor air pollution, considered to be among the worst in the world, indoor air pollution through heating and cooking using coal and other biomass fuels and the contamination of soil and drinking water mean that the Chinese population is exposed to many environmental carcinogens.” Study says.

“Tobacco smoking accounted for about one quarter of all cancer deaths in China; yet over one half of adult Chinese men were current smokers in 2010 and smoking rate in adolescents and young adults is still rising.”

Research suggests that much cancer and many cancer deaths in China could be prevented through reducing the prevalence of risk factors and providing sufficient clinical care facilities to people particularly to those living in rural areas and underprivileged population.
