6. Somatostatin receptor scintigraphy (SRS)
If your doctor does find that there is cancerous material, they may use a test called a somatostatin receptor scintigraphy (SRS) to determine where all the cancerous cells are in your body. This test doesn’t work for all the tumor types listed above, but can be helpful for some. The process begins with a chemical octreotide, which is bound with a radioactive material and injected into the blood stream. A couple hours later the doctors can use a special camera giving them a highlighted look at the problem areas, as well as help determine the best treatment plan.
