25. Somatostatin Receptor Scintigraphy (SRS)
If your test results don’t look great, your doctor may run another test called somatostatin receptor scintigraphy (SRS). This shows where the cancerous cells are in your body, and while it doesn’t work for all types of cancer, it can help identify some of them. First, your doctor will inject octreotide and some sort of radioactive material in your blood stream. Using a special camera, your doctor can then see cancerous cells, which helps your doctor properly diagnose and treat you.
