Four other prospective studies (Helzlsouer et al, 1994; Toniolo et al, 1995; Berrino et al, 1996; Dorgan et al, 1996) have also reported an association between relatively high serum concentrations of oestradiol and increased risk of breast cancer, while two others have reported results that appear negative but that may be statistically compatible with ours (Wysowski et al, 1987; Garland et al, 1992).
