ABSTRACT
Multiple primary cancers, although uncommon, have been increasing in incidence in recent years. This trend is likely due to advances in factors such as diagnostic imaging, life expectancy, and interventional modalities with associated adverse effects. The patient presented in this case report is a 59-year-old Caucasian female with an extensive medical history who developed multiple primary cancers of the breast, mouth, gastrointestinal system, and lung in the span of four years. We attempted to elucidate the possible etiologies and risk factors that may have contributed. Given the patient's complex medical and social history, interventions, environmental, and genetic predispositions, it is impossible to pinpoint a single etiology. Rather, it is more likely that the interplay of multiple factors contributed to the findings of this case.
