Cancer prevention at the microscopic level with the potent power of micronutrients.

Cancer remains a leading cause of morbidity and mortality worldwide, necessitating ongoing exploration of effective prevention strategies. Micronutrients, vital for maintaining cellular health, offer promising avenues for cancer prevention. This review delineates the critical roles of micronutrients in cancer prevention, elucidating their mechanisms at the cellular level. Focusing on essential vitamins and minerals like Vitamins A, C, D, E, selenium, and zinc, we explore their profound effects on fundamental cellular processes such as DNA repair, oxidative stress regulation, cellular proliferation, and immune surveillance. These nutrients, characterized by their antioxidative, anti-inflammatory, and immune-enhancing properties, have shown potential in reducing the risk of cancer. The article synthesizes outcomes from a broad spectrum of clinical trials, epidemiological studies, and systematic reviews to evaluate the efficacy of micronutrients in thwarting cancer development. This critical analysis explores significant trials, addresses controversies in nutrient efficacy, and highlights the implications for clinical practice and public health policy. The review underscores the importance of integrating nutritional strategies into comprehensive cancer prevention frameworks and suggests directions for future research to optimize the preventive potentials of micronutrients.
