Epidemiology and trend of common cancers in Iran (2004–2008)
Cancer is one of the most important causes of mortality worldwide. It includes approximately 13% of death cases. This study aimed to investigate the incidence trend of common cancers in Iran during 2004–2008 to improve reporting distribution the disease.
This was a retrospective study. The study population was all cases of cancer diagnosed in Iran during 2004–2008. The crude incidence rate of cancers was calculated per 100 000 people by age groups and sex. Age-standardised incidence rates (ASRs) were calculated using direct standardisation and the world standard population. Data were analysed using SPSS (version 17) and Microsoft Office Excel 2007.
In this study, a total of 301 055 cases of cancer were diagnosed. ASRs were 60.51 and 84.51 in women and men respectively. Most common cancers in men were skin (ASR = 18.85), stomach (15.02), bladder (ASR = 11.25), prostate (ASR = 8.93) and colorectal (ASR = 8.29). Most common cancers in women were breast (ASR = 18.24), skin (ASR = 12.01), colorectal (ASR = 7.75), stomach (ASR = 7.05) and haematocyte (ASR = 4.01).
A significant increase was observed in the incidence of cancers in the country. Therefore, it is necessary to perform screening, early diagnosis and treatment in early stages of cancers.
