The two countries with the greatest shares of the world's Jewish population are the United States and Israel. The United States had been a hub of Jewish immigration since the nineteenth century, as Jewish people sought to escape persecution in Europe by emigrating across the Atlantic. The Jewish population in the U.S. is largely congregated in major urban areas, such as New York, Los Angeles, and Chicago, with the New York metropolitan area being the city with the second largest Jewish population worldwide, after Tel Aviv, Israel. Israel is the world's only officially Jewish state, having been founded in 1948 following the first Arab-Israeli War. While Jews had been emigrating to the holy lands since the nineteenth century, when they were controlled by the Ottoman Empire, immigration increased rapidly following the establishment of the state of Israel. Jewish communities in Eastern Europe who had survived the Holocaust saw Israel as a haven from persecution, while the state encouraged immigration from Jewish communities in other regions, notably the Middle East & North Africa. Smaller Jewish communities remain in Europe in countries such as France, the UK, and Germany, and in other countries which were hotspots for Jewish migration in the twentieth century, such as Canada and Argentina.

Background/Aims: Ashkenazi Jews have a 1:40 prevalence of BRCA1/2 mutations. Orthodox Jews are an understudied population with unique cultural and religious factors that may influence BRCA1/2 genetic testing uptake. Methods: Using a mixed-methods approach, we conducted a cross-sectional survey and focus groups among Orthodox Jewish women in New York/New Jersey to explore factors affecting decision-making about BRCA1/2 genetic testing. Results: Among 321 evaluable survey participants, the median age was 47 years (range, 25–82); 56% were Modern Orthodox and 44% Yeshivish/Chassidish/other; 84% were married; 7% had a personal history of breast or ovarian cancer. Nearly 20% of the women had undergone BRCA1/2genetic testing. Predictors of genetic testing uptake included being Modern Orthodox (odds ratio [OR] = 2.31), married (OR = 3.49), and having a personal or family history of breast or ovarian cancer (OR = 9.74). Focus group participants (n = 31) confirmed the importance of rabbinic consultation in medical decision-making and revealed that stigma was a prominent factor in decisions about BRCA1/2 testing due to its potential impact on marriageability. Conclusion: In order to increase the uptake of BRCA1/2 genetic testing among the Orthodox Jewish population, it is crucial to understand religious and cultural factors, such as stigma and effect on marriageability, and engage religious leaders in raising awareness within the community.
