“For the life of a creature is in the blood…” Leviticus 17:11
Many were startled in 2012, when it became evident that Israel ranked first in the world in the rate of non-Hodgkin lymphoma (NHL). This cancer of the blood is the fifth most common malignancy in Israel and the eighth most common malignancy among West Bank Palestinians, according to Israel 21C.
A new study has shed light on the risk factors for the disease among Jewish and Arab groups.
Israeli and Palestinian researchers, led by Dr. Ora Paltiel, director of the Hebrew University-Hadassah Braun School of Public Health, conducted a study among 823 Israeli Jews and Palestinian Arabs with B-cell NHL and 808 healthy people as a control group.
The study revealed that in the Jewish and Palestinian populations, overall B-NHL was associated with recreational sun exposure, black hair-dye use, a history of hospitalization for infection, and having a first-degree relative with a blood cancer, according to Israel 21C.
Surprisingly, there was an inverse association with alcohol use. Smoking and greater-than-monthly indoor pesticide use, were connected with certain subtypes of B-NHL.
There were variances among the groups tested. Among Palestinian Arabs, risk factors also included gardening and a history of herpes, mononucleosis, rubella, or blood transfusion, while these factors were not seen in the Israeli Jewish group tested.
