Breast cancer is now recognized as a substantial global health concern. This disease is quite widespread, and it is the leading factor behind women mortality. Despite the fact that disease is found all across the world, its mortality, incidence, and survival rates varied significantly between regions. Breast cancer is a type of cancer that is affected by a range of factors including lifestyle, population structure, genetic factors, and environmental pollutants. Environmental contaminants may serve a crucial part in the etiology of this disease. Prolonged exposure to environmental contaminants, particularly those that have an estrogenic effect, may have a key role in carcinogenesis, particularly in hormone-related cancers like breast cancer. This study reviews various environmental pollutants like pesticides, air pollutants, metals, radiation exposure, water pollutants, solvents, hair dyes, and persistent organic pollutants as potential breast cancer risk factors. Several evidences have established a link between breast cancer and numerous contaminants in the environment. Recognizing the various underlying risk factors for breast cancer could facilitate in preventing the disease.
