By means of 13-year cancer death rate data and meteorological data of Nanning from 1991 to 2003,the impacts of meteorological factors on cancer death were analyzed.It is concluded that weather conditions have indeed certain impacts on cancer death rate: the death toll on high-UV days is obviously greater than that on low-UV days;the death toll of lung cancer increases with increasing air temperature,but that of liver cancer decreases with increasing air temperature,and the latter is more obvious than the former;the death toll of various cancers has a reverse relation with air pressure.Some results is accordant to the related researches overseas.
