Toenail selenium levels and the risk of breast cancer.
The association between toenail selenium and breast cancer was studied in a prospective study on diet and cancer among 62,573 Dutch women aged 55-69 years that started in September 1986.
The analysis was based on 355 breast cancer cases, detected during 3.3 years of follow-up (1986-1989), for whom selenium data were available.
Selenium levels were significantly lower among cases diagnosed early during follow-up.
After exclusion of cases that occurred in the first year of follow-up, multi-variable-adjusted rate ratios of breast cancer in increasing quintiles of selenium were 1.00,0.90,0.76,0.86, and 0.91 (trend p=0.618).
