Oncologic conceptions in the work of the surgeon Guy de Chauliac (c. 1300-1368).

Guy de Chauliac, the most famous surgeon of the middle age, influenced the practice of surgery for centuries. His landmark work, in seven treatises, "Chirurgia Magna" was translated from Latin to French and became popular across Europe, educating hundreds of surgeons. In his book, a series of text fragments were dedicated in cancer such as breast tumor removal, amputation for soft tissue carcinomas of the extremities and cancer treatment using arsenic. Chauliac was probably the first physician to suggest the excision of cancer at early stage and this is considered as a promoter of surgical oncology.
