Cancer Marker Blood Tests in London – What They Reveal & When to Test
By Tharb Faisl
Why Consider Cancer Marker Testing? Cancer can develop silently, showing no symptoms until advanced stages. That’s why tumour marker blood tests are increasingly used in early detection, risk monitoring, and treatment planning.
At Marylebone Diagnostic Centre, we offer discreet, rapid, and accurate cancer marker blood testing tailored to individual risk factors — without needing a GP referral.

What Are Tumour Markers?
Tumour markers are substances (often proteins) produced by cancer cells or by the body in response to cancer. While they don’t diagnose cancer on their own, they are important screening tools when combined with other clinical data.
