It is possible that testicular cancer can be diagnosed by a blood test, although this is not completely reliable. Some men
with testicular cancer (but not all) have raised levels of proteins called tumour markers. There are three main tumour markers
found in men with testicular cancer:
* Alpha-fetoprotein (AFP)
* Beta human chorionic gonadotrophin (BHCG)
* Lactate dehydrogenase (LDH)
70-80% of patients with testicular cancer will have raised tumour markers. Most men will not have a diagnosis made purely
on a blood test - they will usually have an ultrasound scan as well.
If you have symptoms that are causing you concern, then you should see your family doctor (GP). Your doctor will examine
you and can then refer you to your local hospital for tests if necessary.
