title: Cancer of the breast in women born in southern Italy and who migrated to the city of Torino.
abstract: Individual demographic data of 459 women living in Torino with incident breast cancer diagnosed in 1979 were compared with those of a random sample of 1800 women drawn from the list of residents in the same city. Among women aged 25-44 and 45+ years, age-adjusted odds ratios for birth in southern Italy were respectively 1.3 (95% CL, 0.1-2.1) and 0.7 (95% CL, 0.5-0.9). In women aged 45+ years, odds ratios increased with length of residence in Torino.
