Serum‐free thyroxine (FT 4 ) concentrations are lower in Hawaiian and Hawaiian Caucasian women than in Hawaiian Japanese, Hawaiian Filipino, Hawaiian Chinese, and English and Japanese mainland women. There is a high inverse correlation between FT 4 and risk of breast cancer in these ethnic groups. Thyroid‐ stimulating hormone (TSH) concentrations, which are inversely correlated with FT 4 , generally show the same relationship.
