Tumor Marker Blood Tests: Types, Role, Common Markers & Early Detection

Tumor marker blood tests are diagnostic tools used to detect specific substances in the blood that may indicate the presence of cancer.

These tests measure the levels of certain proteins, enzymes, hormones, or other molecules that are produced by cancer cells or by the body in response to cancer.

Examples of tumor markers include prostate-specific antigen (PSA) for prostate cancer, CA-125 for ovarian cancer, and CEA for colorectal cancer.

While tumor marker blood tests are not definitive for diagnosing cancer, they can provide valuable information to healthcare providers when used in conjunction with other diagnostic methods.

The role of tumor marker blood tests in cancer diagnosis is to help healthcare providers assess the risk of cancer, monitor the effectiveness of treatment, and detect cancer recurrence.

These tests can also be used for cancer screening in individuals with a family history of cancer or other risk factors.

What is the Purpose of Performing a Tumor Marker Blood Tests Test?

The purpose of performing a tumor marker blood test is to aid in the early detection, diagnosis, and monitoring of cancer.

These tests can help healthcare providers determine the presence of cancer, evaluate the extent of the disease, and track the response to treatment.

Tumor marker blood tests can also be used to screen for cancer in individuals who are at high risk or to monitor the progression of the disease.

By measuring the levels of specific tumor markers in the blood, healthcare providers can make informed decisions about the best course of treatment for their patients.
