Will tumors show up in blood tests?

Tumour marker blood tests
Tumour markers are substances that might be raised if there is a cancer. They're usually proteins. They can be found in the blood, urine or body tissues. You might also hear them called biomarkers or molecular markers.


Can a blood test reveal a tumor?

Tumor marker tests use a sample of blood to look for chemicals made by cancer cells. These tests don't always help with diagnosing cancer because many healthy cells also make these chemicals. And some conditions that aren't cancer can cause high levels of tumor markers.
