Post-menopausal women with high levels of hormones such as estrogen or testosterone are known to have a higher risk of breast cancer. New research published in BioMed Central's open access journal Breast Cancer Research looked at eight different sex and growth hormones and found that the risk of breast cancer increased with the number of elevated hormones - each additional elevated hormone level increased risk by 16%.
