Physicians reading MRI results

If a physician suspects that a patient might have a neuroendocrine tumor, he or she can use a variety of tests to confirm the diagnosis, such as:

  • A physical examination – Neuroendocrine tumors can produce symptoms that vary from one person to another depending on the type of tumor present and where it’s located within the body. A physician can test for these symptoms during a physical exam.
  • Blood and urine tests – These tests can be used to detect the presence of certain hormones produced by neuroendocrine tumors. For example, because neuroendocrine tumors can secrete serotonin, a patient’s urine may be tested for abnormal levels of hydroxyindoleacetic acid (5-HIAA), which is a breakdown product of serotonin.
  • Imaging tests – Physicians often use imaging tests such as computed tomography (CT) scans, magnetic resonance imaging (MRI) scans, positron emission tomography (PET) scans, ultrasounds and X-rays to detect the presence of neuroendocrine tumors. Certain imaging tests can also be used to determine whether a tumor has metastasized (spread to another area of the body).
  • Endoscopies and biopsies – During an endoscopy, a physician inserts a long, thin tube with a light and camera attached to it into the patient’s body to check for abnormalities. If the physician finds an abnormality, he or she may perform a biopsy, which involves collecting a small tissue sample and sending it to a laboratory for testing by a pathologist.
