The incidence rate of breast cancer is the second highest of all cancers.Alterations to one's epigenome are among the most critical factors in breast cancer control.In breast cancer,nutrients can influence epigenetic pathways and homocysteine(Hcy)levels.Hcy has been related to cognitive decline,Alzheimer's disease,and cancer.Similar to how altered Hcy metabolism is strongly influenced by genetic,epigenetic,and environmental factors,it is significantly linked to cancer.This review aims to discuss the relationship between the levels of Hcy in breast cancer and the effects of nutrients on epigenetic processes.Dietary interventions have the ability to control epigenetic processes,and the Hcy levels are associated with both epigenetic mechanisms and nutritional supplements in breast cancer.Certain nutrients have been discovered to have an impact on these processes.Altered Hcy metabolism is influenced by genetic,epigenetic,and environmental factors and has a substantial link to the emergence of cancer.Nutrients,such as folic acid,vitamin B12 and many phytonutrients that have been found to affect the epigenetic processes in breast cancer may alter DNA methylation and histone modification,which in turn may affect how cancer cells behave.The review emphasizes the need for additional studies to fully comprehend nutrition's potential for the epigenetic mechanism and the relation between Hcy metabolism in breast cancer.
