# Understanding Testicular Cancer Risk: Why Early Screening Helps
What Is Testicular Cancer Screening?
Testicular cancer screening refers to a set of blood tests that measure specific tumour markers associated with testicular health. These markers — including AFP (alpha-fetoprotein), hCG (human chorionic gonadotropin), and LDH (lactate dehydrogenase) — can sometimes highlight changes that may warrant further clinical evaluation. Early screening can play a supportive role in identifying potential concerns before symptoms become more noticeable.
Testicular cancer is the most commonly diagnosed cancer in men aged 15 to 49 in the UK, according to Cancer Research UK. Despite this, awareness around testicular cancer risk and the availability of screening blood tests remains relatively low. Understanding your risk factors and considering proactive blood testing can be a positive step in looking after your long-term wellbeing.
Practical Insight: Testicular cancer screening blood tests do not diagnose cancer on their own. They measure specific biomarkers that, when reviewed alongside other clinical assessments, can help build a clearer picture of health.
Why Does Testicular Cancer Risk Matter?
Testicular cancer accounts for approximately 1% of all cancers in men, but its incidence has been rising steadily in the UK over recent decades. The good news is that outcomes for testicular cancer are among the most favourable of all cancer types when identified early.
Several factors may influence testicular cancer risk, including:
Practical Insight: Having one or more risk factors does not mean someone will develop testicular cancer. Risk factors simply indicate that screening may be worth discussing with an appropriate healthcare professional.
Key Tumour Markers Explained: What Do the Blood Tests Measure?
| **Biomarker** | **Full Name** | **What It May Indicate** | **Normal Reference Range** |
|---|---|---|---|
| AFP | Alpha-Fetoprotein | Elevated levels can sometimes suggest certain types of testicular tumours (non-seminoma) | Typically < 10 ng/mL |
| hCG | Human Chorionic Gonadotropin | Raised levels may be associated with both seminoma and non-seminoma testicular tumours | Typically < 5 mIU/mL in men |
| LDH | Lactate Dehydrogenase | A general marker; elevated levels can sometimes highlight increased cell turnover or tissue changes | 140–280 U/L (varies by lab) |
It is important to note that elevated tumour markers do not automatically indicate cancer. Other conditions, including liver health changes, certain infections, or even vigorous exercise, can sometimes influence these levels.
Practical Insight: A single blood test result is one piece of a larger puzzle. Tumour marker levels are most useful when reviewed alongside personal history, symptoms, and any additional assessments recommended by a healthcare provider.
Who Should Consider Testicular Cancer Screening?
There is currently no routine NHS screening programme for testicular cancer in the UK. This means that men who wish to be proactive about monitoring their health may choose to access private health screening services to check relevant tumour markers.
You may wish to consider testicular cancer screening blood tests if you:
Practical Insight: Self-examination remains an important practice alongside blood testing. Becoming familiar with what feels normal for you can help you notice changes earlier.
How Often Should You Screen?
The frequency of testicular cancer screening depends on your individual circumstances:
Our nurse-led clinic at Private Blood Tests London provides testing and reporting services that allow you to monitor your health at intervals that suit your needs. For a broader look at men’s health screening, see our guide to the 5 key blood tests every man over 40 should consider.
What Do Your Results Mean?
Normal results — All tumour markers fall within standard reference ranges. This is reassuring, though it does not guarantee the absence of all conditions. Regular monitoring remains a positive health practice.
Mildly elevated results — One or more markers sit slightly above the reference range. This can sometimes occur due to non-cancerous causes. It is advisable to seek medical advice for further interpretation.
Significantly elevated results — Markedly raised levels of AFP, hCG, or LDH may suggest that further clinical evaluation is needed. In this instance, it is important to share your results with an appropriate healthcare professional promptly.
Practical Insight: Tracking your tumour marker levels over time — rather than relying on a single snapshot — can sometimes provide a more meaningful picture.

Frequently Asked Questions
What is testicular cancer screening?
Testicular cancer screening involves blood tests that measure specific tumour markers — including AFP, hCG, and LDH — which can sometimes indicate changes related to testicular health. These blood tests do not diagnose cancer but may highlight the need for further clinical assessment.
Who is most at risk of testicular cancer?
Men aged 15 to 49 face the highest testicular cancer risk, particularly those with a family history, a personal history of undescended testicle, or a previous testicular cancer diagnosis.
Can a blood test detect testicular cancer?
A blood test can measure tumour markers that may be elevated in certain types of testicular cancer. However, blood tests alone cannot confirm or rule out a diagnosis. Results should always be discussed with a healthcare professional.
How often should I have testicular cancer screening blood tests?
This depends on your individual risk profile. Men with no known risk factors may choose annual or biannual testing. Those with identified risk factors may benefit from more frequent monitoring.
What happens if my tumour markers are elevated?
Elevated tumour markers do not necessarily mean cancer is present. Various non-cancerous conditions can influence these levels. If your results are elevated, we recommend seeking medical advice.
Is testicular cancer screening available on the NHS?
There is currently no routine NHS screening programme for testicular cancer in the UK. Men who wish to monitor their tumour marker levels proactively may choose to access private blood testing services.
Do I need a referral for private testicular cancer screening in London?
No referral is needed. At Private Blood Tests London, you can book a testicular cancer screening blood test directly.
What are AFP, hCG, and LDH?
These are proteins and enzymes measured in testicular cancer screening blood tests. AFP (alpha-fetoprotein) and hCG (human chorionic gonadotropin) are tumour markers specifically associated with certain testicular tumour types, while LDH (lactate dehydrogenase) is a general marker of cell turnover.
Can young men get testicular cancer screening?
Yes. Testicular cancer most commonly affects younger men, so screening blood tests can be particularly relevant for men in their teens, twenties, thirties, and forties.
Does Private Blood Tests London offer treatment for testicular cancer?
No. Our clinic is a nurse-led service that provides blood testing and reporting only. We do not offer diagnosis, treatment, prescriptions, or scans.
