What are Tumour cell markers?

What are tumor markers? Tumor markers are substances found in higher-than-normal levels in the blood, urine, or tissues of some people with cancer. These substances, which are also called biomarkers, can be made by the tumor. They can also be made by healthy cells in response to the tumor.

What are tumor markers why are they used?

What are the types of tumor markers?

There are many different types of tumour markers, including:

  • alpha-fetoprotein (AFP)
  • cancer antigen 125 (CA125)
  • cancer antigen 15-3 (CA15-3)
  • carbohydrate antigen 19-9 (CA19-9)
  • carcinoembryonic antigen (CEA)
  • human chorionic gonadotropin (hCG or beta-hCG)
  • prostate-specific antigen (PSA)

How reliable are tumor markers?

There has been no evidence to prove that tumor markers are 100 percent reliable for determining the presence or absence of cancer. Many circumstances, such as other health issues or disease, can contribute to raised tumor marker levels.

What is a normal Tumour marker number?

Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.

Can stress cause tumor markers to rise?

The study, which followed 96 patients with chronic lymphocytic leukemia (CLL), found that those who felt more stress and anxiety about about their condition also had a higher volume of cancer cells in their blood and higher blood levels of markers for advanced disease.

What conditions can raise tumor markers?

Tumor markers are substances found in the blood. Tumor marker levels may be higher when there is cancer in the body. They are not very “specific,” meaning non-cancer health issues can also cause these levels to be higher. They must be used along with radiology tests and exams by your healthcare provider.
