Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Selenium has been studied for its potential role in cancer prevention and therapy, primarily because of its antioxidant properties and involvement in DNA repair and immune function. Epidemiological studies have suggested that populations with higher selenium intake may have a reduced risk of certain cancers, such as prostate, lung, and colorectal cancers. Mechanistic studies indicate selenium may help protect cells from oxidative damage and modulate immune responses, potentially inhibiting cancer development.

However, large randomized controlled trials, such as the SELECT (Selenium and Vitamin E Cancer Prevention Trial), have failed to show a significant benefit for selenium supplementation in preventing prostate cancer and, in some cases, suggested potential harm or increased risk when taken in excess. Other studies have similarly found inconsistent or minimal protective effects. The U.S. National Institutes of Health (NIH) and major cancer organizations do not recommend selenium supplementation for cancer prevention or treatment in the general population.

While selenium is an essential micronutrient and deficiency may impair immune function, current scientific evidence does not strongly support its use as a natural therapy for cancer treatment. Its use should be limited to correcting documented deficiencies, and excessive supplementation can be harmful. More research is needed to clarify its role, if any, in cancer therapy.
