Cancer Prevention (Potential)

Selenium intake might lower the risk of certain cancers like prostate, lung, and colorectal cancer. More studies are needed to confirm these findings and clarify the mechanisms involved.

Adequate selenium intake may contribute to cancer prevention by acting as an antioxidant, protecting cells from damage, and influencing immune function and DNA repair mechanisms. These actions may reduce the risk of cellular mutations that lead to cancer development, particularly in the prostate, lungs, and colon. However, more rigorous research is required to establish a definitive causal relationship and understand the optimal selenium levels for cancer prevention.
