DESCRIPTION (provided by applicant): In the USA, prostate cancer (PC) is the second leading cause of cancer-related death in men; aging is a major risk factor and African Americans (AA) are at a higher risk than white Americans (WA). The American Cancer Society estimates that 1 in 9,879 (0-39 year-old), 1 in 39 (40-59 year-old), and 1 in 7 (60-79 year-old) will be diagnosed with invasive PC. Older people develop trace element deficiencies (e.g., selenium); recently, we showed that older rats also develop selenium deficiency. Selenium deficiency increases the risk of oxidative stress and cancer. Selenium-enriched yeast (SY) supplementation has been shown to protect against prostate cancer in humans; however, the dose and the form of selenium as a function of age, as well as the mechanism of action, remain to be elucidated. In a pilot study, we showed that SY (240 5g/day for 9 months) inhibits oxidative stress, reduces PSA levels in healthy men
