distribution of cancer incidence in districts and neighbourhoods of a number of tehran districts in 1386

background: growth of the world population alongside an increasing adoption of cancer-causing behaviors,particularly smoking and various environmental factors. a variety of cancers data in specialgeographic areas can help define medical programs for treatment and screening of high-risk groups.since cancer types has not been reported within districts and neighbourhoods of tehran city so far,this study could be considered as the first in this respect, which defines cancer epidemiology in thecatchment area, and on the other hand, paves the provision of equitable services patient who needthese facilities.the global burden of cancer continues to increase largely because of the aging andmethods: tehran residents covered by the iran university of medical sciences were obtained, which includedalmost 55% of the total cancer incidence in tehran in 2007. districts covered by the university werelocated in west and southwest of tehran including districts 2,5,6,9,18,21, and 22 cases of otherdistricts refered to iran university that identified incidence cancer but results must interpreted withcaution since those resident districts have not been covered population data were obtained from theprevious census in 2006. age and sex standard rate were calculated based on iranian standardpopulation. cancers distribution maps were developed using available adresses, indicating districtsand neighbourhoods in gis. common cancers diffrence within covered districts was tested by fisherexact test.this is the cross sectional study that shows cancer distribution patern. incident cases fromresultsdistrict 6 had the highest incidence (asr=90.552) followed by district 2 (asr=71.503) and the leastincidence was in district 18 (asr=34.991). this diffrence was significant within districts by fisherexact test. the highest asrs in women was 87.517 in districts 6 and 2 (71.621) and in malerespectivly 94.683 and 70.919. highest incidence within neighbourhoods were abasabad,qaemmaqam and gand in males and ddaneshgah, arjantin and shiraz in females. high cancers asrconsisted of breast (9.018), colorectal (4.94), prostate (4.174), stomach (3.711) and skin (3.522).: cancer incidence in specified districts of tehran was 72.822 in 100000 population, whereconclusion: catchment area and districts 1 and 3 out of this territory, warrants more researches to investigate whatfactors in the specified districts and neighbourhoods has led to this condition.more cancer aggregation, which was observed in districts 2 and 6 within the university
