The relation between multiple births and maternal risk of breast cancer.
Data from two case-control studies conducted in New York State during 1982-1986 were used to examine the relation between multiple births and the maternal risk of breast cancer.
The cases were 2,561 women between 20 and 79 years of age with a diagnosis of primary breast cancer.
Controls (n=2,616) were selected from driver's license files and matched to cases by year of birth and county of residence.
The odds ratio for any multiple birth was 0.94 (95% confidence interval (Cl) 0.56-1.56) in women less than 55 years of age and 0.95 (95% Cl 0.62-1.46) in women aged 55-79 years.
