Cancer can also spread through the lymphatic system.
This procedure creates images of your lymphatic system (scintigrams). This is done using a special camera (gamma camera) and a small amount of radioactive material (radiotracer). Images are taken after you are injected with the radiotracer. The radiotracer gives off energy that is picked up by the gamma camera and used to create the images of your lymphatic
