What Are Cancer Marker Tests Used For?

Cancer markers are substances that are made by cancer cells or by normal cells in response to cancer. Most people have these substances at a low level in their blood, but the amount of each marker can increase, sometimes a lot, when there is cancer in the body.

Some tumor markers are specific to one type of cancer, while others may be present in many different types of cancer. If you are also feeling any kind of symptoms, then you can seek advice from an expert specialist via https://cbyelitecare.com/.

Generally, cancer marker tests are done to:

  • look for cancer in people who have a strong family history of particular cancer but don’t have symptoms
  • diagnose cancer
  • see how far cancer has spread (staging)
  • predict how aggressive the cancer is likely to be
  • predict what treatment the cancer is likely to respond to
  • predict how likely it is that cancer will come back (recur) after treatment
  • find out if cancer treatment is working or see if cancer has come back after treatment

Cancer marker tests are usually done in a lab or hospital. You don’t usually need to do anything to prepare for these tests. A lab technologist will take a sample of your blood. The blood sample is then analyzed using special machines.
