Breast cancer remains a global health challenge, prompting a search for preventive strategies beyond conventional approaches. This review explores the potential of specific micronutrients, including antioxidants, vitamins, and probiotics, in breast cancer prevention. Through an extensive literature search encompassing PubMed up to March 2024, 14 micronutrients emerged with promising roles in breast cancer prevention. These include five vitamins: folate, vitamin D, vitamin B6, beta carotene, and vitamin C and nine other micronutrients: curcumin, piperine, epigallocatechin-3-gallate, quercetin, sulforaphane, indole-3-carbinol, lactobacillus, n-3 polyunsaturated fatty acids and lycopene. Understanding the efficacy of these micronutrients could pave the way for personalized preventive interventions, offering new avenues for reducing breast cancer incidence and improving public health outcomes.
