In this 2006 study, birth weight was inversely associated with mother’s smoking status and use of DES during pregnancy.

Exploring whether the positive association between birth weight and breast cancer risk differs by other breast cancer risk factors may help inform speculation about biological mechanism. In these data, high birth weight was associated with breast cancer risk in younger and in more educated women, but was not associated overall.

Birth weight was not associated with attained age, age at first birth/parity, menopausal status, or family history of breast cancer, but was inversely associated with mother’s smoking status and use of DES during pregnancy. An inverse association between birth weight and age at menarche was also suggested.
