While no specific test can detect all sorts of cancer, the body produces certain substances called tumour markers that may signal the presence of cancer. These markers, primarily proteins, are released not only by cancerous cells but also by normal cells, though in significantly higher quantities when cancer is present. Tumour markers may also be found in the blood, body tissues, urine or stool of those with cancer.
Following a thorough evaluation and discussion of your symptoms, your doctor may suggest screening for specific tumour markers. No need to worry about deciding which tests to undergo—your GP will determine this and provide a detailed explanation during your first consultation.
At our Clinic, we offer tumour marker tests with same-day results. Our doctors will carefully review your results, explain their significance, and guide you on the next steps, whether that involves additional testing or treatment.
There are numerous tumour markers, each associated with specific types of cancer. While some markers are linked to a single type of cancer, others are connected to multiple cancer types. These are examples of commonly tested tumour markers:
No single blood test can definitively detect or rule out cancer using tumour markers. For a tumour marker test to reliably detect cancer, it must demonstrate both high sensitivity (the capacity to correctly identify individuals with cancer) and high specificity (the ability to accurately rule out those without cancer). This means a positive result should indicate a high likelihood of cancer whereas a negative result should suggest a low probability. Unfortunately, most known tumour markers do not meet these criteria.
Our doctors may occasionally order a tumour marker test as part of a diagnostic process. However, further testing—including endoscopy or imaging scans—is typically required to confirm or rule out a cancer diagnosis. Tumour marker tests are more commonly used after a cancer diagnosis to track the disease’s progress and evaluate the effectiveness of treatments.
Tumour blood tests are usually recommended by doctors to track the body’s reaction to cancer treatments or to look for recurrence if you’ve had cancer in the past. In cases of pancreatic cancer, tumour marker tests may be helpful in diagnosis.
Our experienced consultants are available to provide consultations and perform blood tests for more than 1,000 medical conditions. If you need to discuss tumour markers testing or any other health concerns, book an appointment today. Take the initial step toward better health and peace of mind.
