The risk factors that often accompany financial prosperity include adopting a western diet, lack of physical activity, and a sedentary lifestyle. These factors contribute to an increased prevalence of chronic diseases andcan gradually increase the risk of gastrointestinal cancers. Therefore, the purpose of this review was to investigate the effect of embracing a western lifestyle on the epidemiology and patterns of gastrointestinal cancers in Saudi Arabia.</p><p><strong>Methods: </strong>I gathered information from various sources in Saudi Arabia regarding the incidence, rate, contributing factors , and other epidemiologic measurements of gastrointestinal cancer. I utilized a range of electronic search platforms, encompassing PubMed, Web of Science, Scopus, Google Scholar, and other electronic databases that met the specified criteria.
