Childhood cancer: an emerging public health issue in China.

On page 176 of the volume 363 of Cancer Letter , Zheng and colleagues described the incidence, mortality and survival of childhood cancer in 2010 and their trends during 2000-2010 period in China mainland. This is a population-based study with a large number of sample size, including approximately 158 million population based on 145 (out of 219) Chinese cancer registries. Although not all registries were included, the potential implications of such an epidemic description on childhood cancer in a rapidly developing large country of China are huge. It would help the health department to make new policies and strategies on the prevention and control of childhood cancer in response to this emerging public health concern.
