Ancient foundations
Hippocratic cancer terminology emerges
460 BC - 370 BC
Hippocrates used the term carcinos for malignant tumors. His descriptions helped establish early medical terminology for cancer and influenced medical thinking for centuries.

Cancer is recognized throughout the body
400 BC - 1800
Over the centuries, physicians recognized that cancer could occur in many parts of the body. Treatment nevertheless continued to rely heavily on Hippocrates' humor-based theory of disease until the nineteenth century.

Origins of modern oncology
Anatomical dissection gains acceptance
1500 - 1699
During the sixteenth and seventeenth centuries, it became more acceptable for doctors to dissect bodies. This allowed physicians to investigate anatomical changes and seek physical causes of death.

Surgical pathology advances through dissection
1600 - 1799
As dissection became more accepted and microscopy spread, physicians increasingly examined tissues and organs to understand disease. These developments helped move cancer study beyond purely humoral explanations.

Microscopy reveals cancer spread
1700 - 1799
The widespread use of the microscope in the eighteenth century contributed to the discovery that the so-called cancer poison could spread from a primary tumor through lymph nodes to other sites.

Percivall Pott identifies an occupational cancer
1775
In 1775, British surgeon Percivall Pott identified a common cancer of the scrotum among chimney sweeps. His observation became an early landmark in linking cancer with an occupational exposure.

Asepsis improves cancer surgery
1800 - 1899
In the nineteenth century, improvements in asepsis and surgical hygiene increased survival after operations. As a result, surgical removal of tumors became the primary treatment for cancer.

Surgery becomes dependent on the individual surgeon
1800 - 1899
With cancer treatment centered on surgery, outcomes became strongly dependent on the individual surgeon's skill in removing a tumor. The art of operative removal dominated treatment during the nineteenth century.
Campbell De Morgan formulates metastasis theory
1871 - 1874
Between 1871 and 1874, English surgeon Campbell De Morgan formulated the view that cancer spreads from a primary tumor through the lymphatic system to other sites, helping establish the modern concept of metastasis.

Key Facts
- One of the earliest known descriptions of cancer appears in the Edwin Smith Papyrus from ancient Egypt, dating to around 1600 BCE.
- The term “cancer” is associated with the Greek physician Hippocrates, who compared tumors to a crab because of their shape and spreading vessels.
- The 19th century brought major advances in pathology, anesthesia, antisepsis, and surgical techniques, making cancer surgery safer and more systematic.
- Radiation therapy emerged after the discovery of X-rays in 1895 and radioactivity in the late 19th century.
- Modern oncology combines surgery, radiation, chemotherapy, targeted therapy, immunotherapy, and precision medicine to tailor treatment to individual patients.
