Diagnosing cancer at an early stage is very important, but it is not easy due to several reasons, and also including lack of symptoms at early stages. Most diagnostic procedures are not suitable for early diagnosis because they can detect tumors of at least 1-2 centimeters in size, or even more. But the tumor markers we are using in daily routine practice are still considered as one of the highly valuable tools for detection and follow-up of malignant tumors.

Before the introduction of modern imaging techniques and recent developments in molecular diagnostics, tumor markers were commonly used as diagnostic tools for the management of cancer patients, and we are still using them in our daily routine. But it is important to choose the right tumor markers in the right settings to optimize patients' health outcomes and to keep healthcare costs reasonable.

Tumor markers have some practical advantages, because they can be measured in body fluids, such as blood and urine, and because they can be obtained with minimal inconvenience to the individuals and their automated essays are available. They also provide quantitative test results and have objective endpoints. Tumor markers are relatively cheap compared to radiological, histological, and endoscopic procedures.
