This study provides a descriptive epidemiological data of thyroid cancer cases diagnosed from 2001 to 2008 among Saudi women, including the frequency and percentage of cases, the crude incidence rate (CIR) and the age-standardised incidence rate (ASIR) stratified by the region and year of diagnosis. This is a retrospective descriptive epidemiological analysis of all Saudi thyroid cancer cases recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008. The statistical analyses were applied using descriptive statistics with the Statistical Package for the Social Sciences version 20.0. A total of 2,930 cases were recorded in the SCR between January 2001 and December 2008. The region of Riyadh in Saudi Arabia had the highest overall ASIR at 9.43 per 100,000 women, followed by Tabuk at 7.11 and eastern region at 6.5, while Jazan and Jouf had the lowest average ASIRs at 1.97 and at 2.72, respectively. The region of Qassim recorded the greatest changes of ASIR at 5.5 per 100,000 women from 2001 to 2008. There was a slight increase in the CIRs and ASIRs for thyroid cancer in Saudi Arabia between 2001 and 2008. Riyadh, Tabuk and eastern region were the highest overall ASIR in Saudi Arabia. While, Jazan and Hail had the lowest rates. Finally, the region of Qassim had the highest changes in CIR and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of thyroid cancer disease among Saudi women.
