Another study presented on Monday (Nov. 26) at RSNA 2007 looked at the influence of the Western lifestyle on breast composition. Miriam Sklair-Levy, M.D., and colleagues from Hadassah Medical Center in Jerusalem compared breast densities of Israeli women and Ethiopian women who immigrated to Israel. The study found that Ethiopian-born women who have immigrated to Israel had significantly lower breast density than did Israeli-born women. In addition, past Ethiopian immigrants who had begun to adopt a Western lifestyle (decreased number of children, change in diet or increased hormone use) had significantly higher breast density than recent immigrants.

At a Glance
-- Women who live in cities have denser breast tissue than women who live
in suburban or rural areas.
-- Women with dense breasts are at an increased risk of developing breast
cancer.
-- In the study, the risk of increased density was twice as great in
women 45 to 54 years old.
