oa Demographic variation of cancer incidence in Jordan 2001–2011 (age and sex an example)

Background: Age and sex are major determinants of cancer incidence. The objective of the study is to explore epidemiology of cancer in Jordan by age and sex for 2001–2011.

Methods: Descriptive study done, cases were identified from Jordan cancer registry (JCR), all Jordanian cancers patients that diagnosed and registered in 2001–2011 were included variables collected SPSS 20 used for analysis.

Further detailed studies about risk factors of cancer to age group and sex. Considering these data about age and sex in cancer screening programs in the future.
