To explore nasopharyngeal cancer (NPC) incidence and pathological data of Zhongsha, China, in 1970-2007, and to provide scientific information for prevention and control.From Zhongshan Cancer Registry NPC data, incident numbers, crude incidence rates, age -adjusted incidence rates, proportion of pathology and incident trends were calculated and analyzed.The male and female NPC world age-standardized incidence rates were 27.5/105 and 11.3/105 respectively, and were relatively stable in 1970-2007 in Zhongshan. The non-keratinizing type accounted for 84.6 percent of all NPC new cases and the keratinizing type only 5.8 percent, and there was no obvious change in pathological proportions over 38 years.NPC incidence level was high and stable in Zhongshan in 1970-2007. It suggested that its prevention and control should be enhanced.
