Oncology
circa 1600 BCE, ancient Egypt — Edwin Smith Papyrus
Squamous cell carcinoma, a malignancy arising from squamous epithelial cells, has left traces in the historical record stretching back to antiquity, where ancient physicians described ulcerating growths of the skin and mucous membranes without understanding their cellular nature. For most of recorded history, such lesions were grouped under broad categories like cancer or noli me tangere, reflecting both the difficulty of their treatment and the terror they inspired. The modern understanding of this cancer's origin in specific cell types emerged only after the development of cellular pathology in the nineteenth century.
Historical Narrative
Ancient Egyptian medical papyri, including the Edwin Smith Papyrus dating to approximately 1600 BCE and believed to copy older sources, contained descriptions of surface tumors that physicians of the era regarded as incurable. Egyptian healers applied caustic substances and hot irons to such lesions, practices that reflected an empirical recognition that destroying tissue could sometimes arrest visible growth even when no theoretical explanation was available. The Ebers Papyrus similarly referenced treatments for ulcerating skin conditions using plant-based preparations, and the willingness of ancient practitioners to intervene surgically suggested a pragmatic, if limited, therapeutic tradition.
Hippocratic writers in ancient Greece grouped malignant surface growths under the term karkinos, meaning crab, a name said to reflect both the grasping extensions of larger tumors and the pain they caused. Hippocratic theory attributed such growths to an excess of black bile, the cold and dry humor whose accumulation was believed to corrupt tissues. This humoral explanation persisted with remarkable durability through the centuries, shaping both diagnosis and treatment in the ancient and medieval worlds. Galen refined and codified these views in the second century CE, and his authority ensured that humoral explanations dominated Western medicine for more than a millennium.
Medieval physicians encountering ulcerating facial or oral lesions often employed the term noli me tangere, meaning touch me not, for lesions considered too dangerous or intractable to treat aggressively. This linguistic retreat reflected therapeutic pessimism rather than scientific classification. Cauterization and herbal applications remained the primary interventions, and surgical excision, while practiced, was performed without anesthesia or antisepsis, limiting its success and application.
The renaissance of anatomical study in the sixteenth and seventeenth centuries gradually reoriented thinking about the body, though tumor classification remained crude. Ambroise Paré, the influential French surgeon of the sixteenth century, described excision techniques for surface cancers and reflected on the likelihood of recurrence, demonstrating a clinically sophisticated, if still humoral, understanding of malignant disease.
The most transformative intellectual shift came in the nineteenth century with the work of Rudolf Virchow, whose cellular pathology, developed in the 1850s, established the principle that disease arose from abnormalities in cells rather than in humors or fluids. Virchow and his contemporaries could now examine tumor tissue under the microscope and describe what they saw with precision. The identification of carcinomas as malignancies originating in epithelial cells, and the further distinction of squamous cell types based on their microscopic appearance, gave pathologists a new vocabulary and a new set of diagnostic criteria grounded in observable biological structure.
The occupation-related origins of certain squamous cell carcinomas attracted important scientific attention in the eighteenth and nineteenth centuries. Percivall Pott's 1775 observation that chimney sweeps in England developed scrotal cancers at unusually high rates represented one of the earliest documented associations between environmental exposure and a specific malignancy. Pott's insight, that the soot these workers encountered chronically was causally linked to their tumors, established a framework for thinking about carcinogenesis that later researchers would develop into the field of occupational and environmental oncology, fundamentally reshaping how scientists understood why cancers of epithelial surfaces arose in particular populations.
