Breast cancer trends in Israeli Jewish and Arab women, 1996-2007.
Breast cancer is the most common malignancy in Israeli Jewish and Arab women. The main objective of this study was to reexamine the trends in breast cancer incidence, mortality, and survival in Israel in 1996 through 2007, as well as the use of mammography. Data were obtained from the Israel National Cancer Registry, the Central Bureau of Statistics, and National Health Surveys. Incidence and mortality rates per 100 000 are age adjusted to the world standard population. Time trends are presented using the joinpoint regression analysis. The relative survival was calculated for the diagnosis years 1996-2003. Data on mammography performance were obtained from the Knowledge, Attitudes and Practices surveys carried out in 2002-2008. From 1996 through 2007, the incidence of in-situ breast cancer increased in both subpopulations whereas the incidence of invasive breast cancer decreased by 3% for Jewish women and increased by 98% for Arab women (P value for 'between-populations' differences <0.001). Reports on having had a mammogram in the last 2 years increased by 16% in Jewish women and by 17% in Arab women in 2002 through 2008 (P=0.880). Breast cancer mortality rates decreased significantly from 24.7 in 1996 to 19.0 in 2007 in Jewish women, but remained stable in Arab women (P=0.041). The 5-year relative survival increased in both subpopulations (P=0.420). The incidence of breast cancer has been stable in Jewish women, but had been increasing rapidly in Arab women throughout 1996-2007. The differences indicate an epidemiologic transition in the Arab minority in Israel. Efforts should focus not only on secondary but also on primary prevention strategies.
