Plasma carotenoids and risk of breast cancer over 20 y of follow-up.
This 20 years follow-up study examined the association between carotenoid intake and breast tumors. 32.826 women donated blood samples. 11–12 years later, 18.743 of these women contributed a second blood sample. Between the first and second blood collection, 2188 breast cancer cases were diagnosed. The results showed that women with high carotenoid intake had a reduced breast cancer risk, particularly for more aggressive and fatal disease. Further details can be found in the study.
