Tumour Marker Test

A tumour marker test measures specific substances in the blood, such as PSA, CA-125, CEA or AFP, that can be elevated in the presence of certain cancers or, in some cases, non-cancerous conditions. These markers are used to help monitor known cancers for response to treatment or early signs of recurrence, though they are generally not reliable enough to diagnose cancer on their own due to variable sensitivity and specificity. They are most useful when tracked over time in a patient with a known cancer diagnosis, where a rising trend can signal disease progression before it becomes apparent on imaging. Because levels can be elevated by benign conditions as well, results are always interpreted alongside clinical findings and other diagnostic tests.

Tumour Marker Test is recommended for patients diagnosed with specific conditions where other approaches have been insufficient. Your Medical Oncology specialist will assess your suitability based on your diagnosis, health history, and treatment goals.

Side effects vary by individual and are detailed in the section above. Your specialist will discuss all risks and benefits with you before treatment begins. Serious adverse effects are uncommon but are part of the informed consent process.

Tumour Marker Test has a documented success rate of Variable sensitivity, used alongside imaging at accredited facilities. Outcomes depend on disease stage, patient health, and adherence to the treatment plan and aftercare instructions.
