Abstract: Objective The present study was conducted tO analyze the incidence and mortality distribution characteristics of malignant tumors among the urban residents in Wucheng District from 2003 to 2005 and provide basis for establishing prevention and control schemes of tumors．Methods Epidemiological analysis was conducted on the incidence and mortality of malignanttumors of the urban residents in thiS district from 2003 t0 2005．Results From 2003 t0 2005．854 cases with malignant tumors were found，and 828 cases died．The incidence in 2003 was the highest(202.73/lalda)，while that in 2004 was the lowest(186.54/lakh)．The annual standardized in-cidences were a11 above 180/lakh．The annual mortalities were about 170-200/lakh and the stan- dardized mortalities were all about 180-190/lakh．The incidence and mortality were higher in males than females．The age-specific incidence and age-specific mortality both rised as age in-creased．Patients who were found tO have or died of malignant tumors were mainly more than 40 years old．Malignant tumors in males were mainly lung cancer and digestive system tumors，and in females breast cancer，lung cancer and digestive system tumors were the main malignant tumors，in which breast cancer was at the top．Conclusion ne incidence and mortality of malignant tumors in urban residents are both high as the top death cause．Suggestions are as follows：establishing prevention and control schemes of tumor which were carried on by the government；developing surveillance report on chronic diseases such as malignant tumors；paying more attention to the pre-vention and control of lung cancer，breast cancer and digestive system tumors；conducting researchon the risk factors of malignant tumors；generalizing health education on cancer prevention；con-ducting community comprehensive prevention of malignant tumors．
