Test for Tumor markers

Tumor markers are substances produced by cancer cells which can be found in the blood, body fluids, or tissues. The two main purposes of taking a test for tumor markers are to sense the existence of certain types of cancer in the body, and to monitor the progress of cancer treatment.

Particularly, this test is employed to examine the success of recent therapy, assess the need for surgical intervention, or evaluate the development of recurrence. If a certain tumor marker is found in the body, it can signify that the cancer is still present and ongoing treatment may be suggested.


Common Tumor Markers
Some cases of common tumor markers include:

  PSA: valuable marker for supervising disease evolution in prostate cancers.
CEA (carcinoembryonic antigen): functional in monitoring patients with diverse types of malignancies, such as gastrointestinal, pancreatic, breast, and lung cancers.
  CA15-3: sensitive tumor marker for breast cancer.
CA19-9: some patients with gastrointestinal tumors have presented elevated antigen in the blood.
  CA-125: useful marker for observing disease progression in ovarian cancers.
