From Ancient Cauterization to Engineering the Body's Own Immune Defense
In short: This lecture by Professor Eleanor Stride traces the long arc of oncology, from primitive surgeries in Egypt to modern immunotherapy. It explores how our understanding of cancer has shifted from mystical humors to cellular biology and evolutionary theory.
The history of cancer treatment is a journey of increasing precision. In 3000 BCE, Egyptian texts like the Edwin Smith papyrus described treating tumors with cauterization. By 400 BCE, Hippocrates coined the term 'karkinos' (crab) to describe how tumors spread. For centuries, Galen’s theory that cancer resulted from an excess of 'black bile' dominated medical thought until the 18th and 19th centuries.
Modern oncology was born through anatomical pathology in 1761 and the development of cell theory in the 1850s. Rudolf Virchow demonstrated that tumors arise from healthy cells, a breakthrough that paved the way for radiotherapy and chemotherapy. Today, research focuses on clonal evolution and immunotherapy, which aims to harness the patient's own immune system to eliminate disease.
