Background:

Breast cancer is the most prevalent malignancy in women. Epidemiology of breast cancer shows differences between populations around the world. Differences in mortality rates were reported as well. In Israel, breast cancer prevalence is lower among Arab compared to Jewish women, but incidence is increasing among Arab women at a younger age. The results of our previous cross-sectional study indicate on differences in exposure to hormonal medications between Arab and Jewish women with breast cancer, with lower use of combined oral contraceptives (OCCP) and HRT and higher use of progestogens and medications for treatment of infertility.

Research questions:

Is there an association between use of progestogens and medications for infertility and incidence of breast cancer in Arab women in Israel?

Method:

a case-control study comparing Arab and Jewish women with breast cancer and their use of hormonal medications from various types: OCCP, HRT, progestogens and medications for treatment of infertility. The population of the study will ininclude Arab and Jewish women, cared by Clalit Health Services at age 30-60, that were diagnosed with breast cancer in the years 2023. The data on use of hormonal medication will be rtrieved for the years 2000-2022. The analysis will be comprised of the description, comparing rates of use of hormonal medications between the groups, and calculation of OR in relation to each medications and combination of use, in adjustment with other risk factors, like age, number of pregnancies, age of first pregnancy, age at menopause, obesity at menopause, smoking

Results:

Ongoing study, there are no preliminary results yet

Conclusions:

Ongoing study, there are no preliminary results yet

Points for discussion:

Previous studies have indicated a possible contribution of the use of hormonal medications to breast cancer, with different conclusions related to the type of hormones.

We suggest that the differences in breast cancer between Arab and Jewish women in Israel may be associated with the social changes being experienced by Arab women in Israel.
