But Dr. Lital Keinan-Boker of the University of Haifa, and colleagues compared the cancer rates in a cohort of over 300,000 Israeli Jews who were born in Europe and immigrated to Israel before or during World War II (the non-exposed group) with cancer rates in a cohort of European-born Israeli Jews who immigrated from Europe AFTER World War II*. The strongest associations were with breast and colorectal cancer.
A companion study from the University of Texasâ€”MD Anderson Cancer Center in Houston, discuss these results in European-born Israeli Jews and those of several past studies of calorie reduction and cancer risk. They say the data from this study add to the growing body of literature on the effects of severely restricted calorie intake and of unimaginable psychosocial and physical hardships on cancer risk. They wrote, “From this unique cohort we can learn lessons about adaptation to extreme hardships in early life, resilience during life, and cancer susceptibility later in life.”

** Note 2. Exposure was based on immigration dates because no individual data were available on actual Holocaust exposure.
Note 3. I guess they should compare the results to Jewish post war immigrants to Australia and the US, and dare I say, Canada. and see what the results are, in order to correct for the Israeli diet and stressful environment versus the North American diet.
