MATERIALS AND METHODS Data were collected from Khuzestan cancer registry which is a branch of Iranian Ministry of Health Cancer Registry (http://ircancer.ir) for the period 2004-2008. Data were presented as incidence rates by site, sex, age, using the crude rate and age-standardized rate (ASR) per 105 persons. A direct method of standardization was applied according to the WHO guideline and data analysis was performed using the SPSS package. RESULTS During the 2004-2008 period, 14,893 new cases of cancer were registered in Khuzestan cancer registry. The age- standardized incidence rate of all cancers was 153.7 per 105 in males and 156.4 per 105 in females. The incidence was increased over the period of five years. The most incident cancers among males were skin cancer (ASR =18.7/105), stomach cancer (ASR13.8/105), lung cancer (ASR12.9/105), leukemia (ASR=12.6/105) and prostate cancer (ASR=12.4/105).
