What is a Cancer Marker Test?

A cancer is a serious health concern, and early detection and treatment are crucial for improving treatment success and survival rates. Cancer markers are certain biomolecules that exhibit abnormal expression within a patient’s body and are associated with the occurrence, development, and prognosis of cancer. Testing for cancer markers can serve as auxiliary tools for cancer diagnosis and monitoring, helping doctors assess the status of cancer and treatment effectiveness.

Cancer markers can include proteins, enzymes, antibodies, genetic materials, and more. Here are some common cancer markers and their applications:

  • Alpha-fetoprotein (AFP): Used for monitoring liver cancer and evaluating treatment responses.
  • Carcinoembryonic antigen (CEA): Commonly used for diagnosing colorectal cancer, monitoring treatment effectiveness, and assessing the risk of recurrence.
  • Cancer antigen 125 (CA-125): Mainly applied for diagnosing and monitoring ovarian cancer.
  • Prostate-specific antigen (PSA): Used for diagnosing and monitoring prostate cancer, though it may also elevate in other non-cancerous conditions.
  • Acid phosphatase (ACP): Frequently used for monitoring prostate cancer and evaluating treatment responses.

Testing for these cancer markers is typically done through blood, urine, tissue samples, etc. However, it’s important to note that an elevated level of a single cancer marker cannot definitively confirm the presence of cancer, as other non-tumor factors can also lead to marker fluctuations. Therefore, a comprehensive assessment and judgment are usually necessary, taking into account clinical history, symptoms, other test results, and imaging studies.

The application of cancer markers aids in early cancer screening and monitoring treatment effectiveness. However, they are not used for screening all types of cancer and may yield certain false positive and false negative results. Therefore, the use of cancer markers should be guided by a healthcare professional and interpreted based on each patient’s specific circumstances.

In conclusion, cancer markers are specific biomolecules with value in cancer diagnosis and monitoring. They can serve as auxiliary diagnostic tools for cancer, assisting doctors in assessing cancer status and treatment effectiveness. However, the results of cancer marker tests need to be considered alongside other relevant factors and interpreted under medical guidance. If you have any suspicions or questions, please consult a healthcare professional promptly for accurate diagnosis and appropriate treatment. Early detection and treatment of cancer are key to improving treatment success and survival rates.
