Tumour markers are proteins found in the blood, tissue or urine that may be directly produced by a tumour or by other tissues in response to the presence of a tumour. They can be used to screen for the presence of cancer and monitor the course the disease is taking.
Prostate cancer is the second most common cause of cancer in men. If it is detected early enough, it has a 90% cure rate. CEA, a non-specific cancer antigen produced in response to malignant cells, is measured in addition to total and free PSA. Therefore, testing for CEA simultaneously with PSA provides a more accurate diagnosis of prostate cancer.
