Due to the polluted environment and modern way of living, tumorous diseases are becoming increasingly responsible for human deaths. Tumorous diseases can appear in any multicellular organism in some form. Traces of them have been identified in prehistoric people as well as in Egyptian mummies. The widespread word CANCER has its origin in ancient Greece. The first reports of laboratory evidence of tumorous diseases were published in scientific publications as early as the mid-19th century. This was the time of the onset of clinical biochemistry as a branch of science and medicine. Laboratory techniques did not exist then and testing was based on simple physico-chemical reactions. It was only in the second half of the 20th century that the study and examination of tumour markers enjoyed rapid development. Currently, the most common tumour can be determined by nearly any biochemical laboratory. The subject of my paper, "Tumour markers" is very broad - actually, each chapter would deserve to be an independent subject - and still, my thesis is far from a detailed analysis of each individual marker and methods of its determination. I aimed at providing a brief overview of the...
