Circa 1600 BCE (possibly copying material from circa 2500 BCE), ancient Egypt — Edwin Smith Papyrus
Breast cancer held a documented place in medical history stretching back more than four thousand years, representing one of the earliest cancers described in surviving written records. Healers across antiquity, the medieval period, and the early modern era struggled to explain its origins and developed a range of treatments reflecting each era's dominant theories of disease. The transition from humoral and constitutional explanations to cellular and molecular understandings unfolded gradually across the nineteenth and twentieth centuries.
Historical Narrative
The oldest known description of breast cancer appeared in the Edwin Smith Papyrus, an ancient Egyptian surgical text dated to approximately 1600 BCE but believed to copy material from as early as 2500 BCE. The document described bulging tumors of the breast that were cool to the touch and had no cure, representing a remarkably candid clinical observation for its era. Egyptian healers apparently treated some breast conditions with cauterization, applying heated implements to the affected tissue.
Hippocratic physicians of ancient Greece interpreted breast cancer through the lens of humoral theory, attributing tumor formation to an excess and stagnation of black bile — the humor associated with earth, coldness, and dryness. This interpretation gave the disease its enduring name, as the Greek word for crab, karkinos, was applied to describe the hard, claw-like extensions some tumors appeared to produce into surrounding tissue. Galen of Pergamon, writing in the second century CE, elaborated on the black bile theory and explicitly discouraged surgical intervention for deeply rooted tumors, arguing that surgery would merely agitate the corrupt humor and hasten death. He recommended instead systemic treatments aimed at purging black bile, including dietary modification, purging agents, and phlebotomy. Galen's enormous authority ensured that these ideas dominated European medical thinking for over a millennium.
Medieval European physicians, working within the Galenic tradition, largely perpetuated humoral explanations and systemic treatments. Surgeons occasionally performed excisions of smaller or more accessible tumors, but such operations carried enormous risks in the absence of anesthesia or antiseptic technique. Hildegard of Bingen and other medieval healers incorporated herbal applications and spiritual interventions alongside more physical treatments.
The Renaissance began to crack the humoral edifice as anatomists like Andreas Vesalius produced more accurate descriptions of human anatomy. By the seventeenth century, physicians including Franciscus Sylvius began attributing cancer to acidic lymph rather than black bile, reflecting a shift toward chemical explanations of disease. The Dutch surgeon Johannes Scultetus provided detailed surgical descriptions of breast operations in the seventeenth century.
The eighteenth century brought more systematic surgical approaches. Scottish surgeon John Hunter argued that cancers grew from lymph and proposed principles for determining when tumors might be operable. Henri François LeDran in France argued that cancer spread through the lymphatic system, a crucial conceptual advance that redirected thinking toward surgical removal of regional lymph nodes.
The nineteenth century transformed cancer surgery through two major developments: the introduction of anesthesia in the 1840s and antiseptic surgical technique promoted by Joseph Lister in the 1860s and 1870s. American surgeon William Stewart Halsted developed his radical mastectomy procedure in the 1880s and 1890s, premised on the theory that breast cancer spread in an orderly, centrifugal fashion from its origin. The Halsted radical mastectomy became the dominant surgical approach for most of the twentieth century.
In parallel, the cellular theory of disease advanced by Rudolf Virchow in the mid-nineteenth century established that cancers arose from abnormal cell proliferation, providing a new scientific foundation for understanding malignancy. By the early twentieth century, researchers began investigating hormonal influences on breast cancer, a line of inquiry that extended through George Beatson's earlier observations in the 1890s that oophorectomy could cause tumor regression in some patients.
