Cancer biomarkers

  • What are the indicators of a cancer tumor?

A tumor marker is anything present or produced by cancer cells or other body cells in response to cancer or some benign (non-cancerous) condition that provides information about cancer. like how aggressive he is, And what kind of treatment he might respond to or whether he’s responding to treatment.

Tumor markers have traditionally been proteins or other substances that cancer cells make in higher amounts than normal cells. It can be found in the blood, urine, stool, tumors, other tissues, or body fluids of some cancer patients. However, Genomic markers (such as tumor genetic mutations, and tumor gene expression patterns, and non-genetic changes in tumor DNA) found in tumors themselves and in tumor fragments infused into body fluids.

  • How are cancer tumor markers tests used ?

  1. High levels of tumor markers can be a sign of cancer. Along with other tests, Tumor marker tests can help doctors diagnose certain types of cancer and plan treatment. Tumor marker tests are commonly used to do the following:
  2. Find out if the person has cancer. Higher levels of tumor markers may indicate a specific type of cancer. Tumor markers testing may be used as part of the initial diagnosis.
  3. Guide treatment decisions. Some tumor marker tests tell doctors whether to give chemotherapy or immunotherapy. Others help doctors choose which medications may work best.
  4. Check the progress of treatment. Changes in levels of tumor markers can show how well treatment is working.
  5. Anticipate the chance of recovery. Tumor markers can help doctors predict the behavior of cancer and response to treatment. They can also predict your chance of recovery.
  6. Anticipate or monitor recurrence. Recurrence occurs when the cancer comes back after treatment. Tumor marker tests can help predict how likely this is to occur. That’s why these tests may be part of your care after treatment ends. They may help find a repeat sooner than other tests.
  7. Tumor marker tests may also be used to look for cancer in people at high risk of developing the disease. Or, you may have these tests to learn more about the cancer when doctors first discover it.
  • Limits of Tests for Cancer Tumor Indicators

Tumor marker tests are not perfect. They are often non-specific to cancer and may not be sensitive enough to pick up cancer recurrence. The presence of tumor markers alone is not enough to diagnose cancer. You may need other tests to learn more about the possibility of developing or recurring cancer. Some of the limitations of tumor marker indicators are listed below.

A non-cancerous condition or disease can raise tumor marker levels.

People who don’t have cancer can have high levels of tumor markers.

Tumor marker levels can change over time. Tests may not get the same result every time.

Tumor marker levels may not rise until the cancer has gotten worse. This does not help detect cancer early, or in people at high risk. It also does not help in finding redundancy.

Some cancers do not make the tumor markers found in the blood. Some types of cancer have no known tumor markers.

Your tumor marker levels may not be elevated. Even if the type of cancer you have is usually making tumor markers.

  • How are tumor markers tested?

A member of your health care team will take a sample of your blood or urine. The sample goes to a laboratory for testing. Some tests must be done more than once, Because tumor marker levels can change regularly.

You’ll also need other tests to find cancer and to verify treatment. This is because tumor marker results have limitations and are sometimes false. They may do the following:

Show that a tumor is present or growing when it is not.

Show the absence of a tumor when present, Or show that a treatment works when it doesn’t.

There is no perfect test. So your doctor will likely order several types of tests to find answers.

  • Tumor marker tests for certain types of cancer

Doctors use different tumor marker tests for different types of cancer. However, Many cancers do not yet have tumor markers that can help guide care.

  • Questions to ask the health care team

You may want to ask your health care team these questions:

  • Do you think I need any tests to identify the tumor? Which ones and why?
  • Have you already looked for signs of a tumor? Any one?
  • How are these tests performed? How often should I get it?
  • Who can explain the results to me?
  • If I have abnormal levels of tumor markers, So what does that mean? How might this result affect my treatment plan?
  • Will I need tumor marker tests after cancer treatment ends?
  • Where can I learn more about tumor markers and testing?
