  1. Season of birth and breast cancer risk in Sweden.

    Article - En anglais

    Recent research suggests that intrauterine exposures, perhaps factors that influence birth weight and other indicators of fetal growth, may affect future breast cancer risk.

    Because birth weight shows seasonal variation in Sweden, we assessed whether risk for breast cancer is associated with month of birth.

    The analyses included all 115,670 women, born between 1858 and 1968, who were reported to the Swedish Cancer Registry in 1958-89 as having breast cancer.

    Poisson regression models were used to examine the data.

    After adjustment for seasonality of number of live births in the population at risk, a significant seasonal pattern was identified for women born between 1880 and 1920.

    Women born in June had a 5% higher risk of breast cancer than those born in December.
