It 's almost become a catchphrase, from which it seems that you can not get out. Many patients undergoing laboratory tests, among which is also present as a cancer marker CEA, CA19.9, CA 15.3; Alpha fetoprotein etc etc. The result is often dramatic, even modest increases compared to the reference values \u200b\u200bare the cause of self-diagnosis of cancer!
Warning! markers are a valuable tool in the hands of those who know their true value and can interpret the results.
The marker can not and should not be considered as an indicator of mass SCREENING! In fact, numerous studies have shown that changes in parameters than the reference value, are caused by false positives!
