1975—1987年恶性肿瘤统计资料表明,苍梧县鼻咽癌死亡,占各种恶性肿瘤死亡的21.9％,居第二位。十三年来,鼻咽癌的发病和死亡率不仅高且相对稳定,虽有波动,但无明显升降趋势。发病率波动在10.40—14.72/10万之间,提示苍梧县的地理环境中,可能存在某些较强且恒定的致癌物质,有待进一步探索。 Statistical data on malignant tumors from 1975 to 1987 showed that nasopharyngeal cancer in Cangwu County was dead, accounting for 21.9% of all malignant tumor deaths, ranking second. In the past 13 years, the incidence and mortality of nasopharyngeal carcinoma were not only high but relatively stable. Although there were fluctuations, there was no significant increase or decrease. The incidence rate fluctuates from 10.40 to 14.72/100,000, suggesting that there may be some strong and constant carcinogens in the geographical environment of Cangwu County, which needs further exploration.
