Avenzoar's (1091-1162) clinical description of cancer.

Abstract

In the 11(th) and 12(th) century the Western caliphate flourished, making Cordoba the capital of physicians and philosophers. During that period lived and practised the famous physician Ibn Zuhr or Avenzoar. In his monumental treatise Al Taysir, Avenzoar provided the first clinical description of a polypoid colorectal tumour as well as the case of a uterine cancer and a basal cell carcinoma. His medical work remained popular through middle ages, influencing the development of western medicine.
