What a tumour marker test can and can’t tell you
Tumour markers are substances that can be raised when certain cancers are present, but they can also rise for other, non-cancerous reasons, and a normal result doesn’t rule cancer out. They’re most useful alongside symptoms, an examination or a scan.
If your result is raised, we’ll recommend sharing your report with your GP so they can decide whether further tests are needed. If you have worrying symptoms, please see your GP promptly rather than relying on a blood test alone.
Frequently asked questions
Can a blood test detect cancer?
Tumour marker tests such as PSA and CA-125 can be raised in some cancers, but they can also be raised for other reasons and are not a diagnosis on their own. They are best used alongside symptoms, examination and imaging.
