Natural Radioactivity of Tobacco and Its Role in Cancer Development abstract

Background: Tobacco use has remained a significant public health challenge worldwide dueto its strong association with various cancers. One of the little-known factors contributingto tobacco-related cancers is the presence of naturally occurring radioactive substances intobacco leaves. These naturally occurring radionuclides, such as radium-226, actinium-228,bismuth-214, and radium-228, originate from soil and fertilizers used in tobacco growing.Materials and Methods: In this review study, articles were collected from Medline, PubMed,Scopus, and Google Scholar search engines using keywords: “natural radioactivity,” “tobacco,”“cancer development,” “cigarette,” “smoking,” “cancer,” “carcinogenesis,” “radioresistance,”and “radiotherapy.” Articles were searched without a time limit. The inclusion criteria werearticles written in English and having full-text availability.Results: The studies demonstrate a strong correlation between smoking and side effects ofcancer treatment. These effects are not limited to specific cancer types but have been observedacross various malignancies and therapies.Conclusion: The carcinogenic mechanism of tobacco is very diverse and complex, involvingboth chemical and radiobiological factors. Understanding these mechanisms can help developsensitive methods to identify signature carcinogens in tobacco, facilitating effective andtargeted epidemiological studies.
