Diagnosing a Mouth or Throat Tumor

You have a tumor in your mouth or throat. A tumor is a mass of abnormal cells. To learn more about your tumor, your healthcare provider will evaluate you. This may include a health history, physical exam, and some tests. The results help your provider and healthcare team plan the best treatment for you.

Your health history

Your healthcare provider will take your health history. They'll ask about your health problems, symptoms, and any treatments you’ve had. It's vital that you share all important health information with your provider. If needed, you may be referred to a specialist for more evaluation.

Your physical exam

The physical exam is done in a healthcare provider’s office. The provider will look inside your nose and mouth with a light. They'll also feel your neck and maybe your mouth. The following may be done during the exam as well:

  • Indirect laryngoscopy. A handheld mirror is held to the back of your throat. The provider directs a light to the back of your throat to check the larynx, vocal cords, the base of the tongue, and other tissues in your throat. A numbing medicine may be used to keep you comfortable.

  • Panendoscopy. Different types of tubes (endoscopes) are put into your mouth or nose, and sometimes down into your throat. This is usually done in the hospital with general anesthesia so you can sleep during the test.

 

Imaging tests

You may have 1 or more imaging tests. These give your healthcare provider more information about your tumor. You’ll be told how to get ready for these tests ahead of time. Some common imaging tests include:

  • X-ray. This test uses high-energy beams to take a picture of tissues inside the body.

  • CT scan. This uses a computer and X-rays to take detailed pictures of your body.

  • MRI scan. This test uses strong magnets and computers to take images. The test does not use X-rays

  • PETCT scan. A PET scan uses a small amount of a radioactive substance to show areas that might be cancer. The PET-CT scan is 2 tests done at the same time. This creates a more detailed image.

Direct pharyngoscopy and laryngoscopy

For a closer look at your throat, larynx, and other nearby tissues, your healthcare provider may do direct pharyngoscopy and laryngoscopy. During this test, the provider puts a lighted tube (laryngoscope) into your throat. Direct laryngoscopy is often done in the hospital.   You'll be given general anesthesia to help you relax and sleep through the test.

Biopsy

A biopsy means the healthcare provider removes a small sample of your tumor. This sample is then sent to a lab and studied. This test is done to find out if the tumor is cancer. A biopsy may be done in the provider’s office or in the hospital. In some cases, the provider does a biopsy during direct laryngoscopy.

Fine-needle aspiration

For fine-needle aspiration (FNA), the healthcare provider puts a very thin needle attached to a syringe into the tumor. Then they and pull out some cells that will be examined in a lab. This type of biopsy is sometimes done in the provider’s office.

Deciding on treatment

Treatment depends on the tumor’s size, type, and where it is. Treatment also depends on if the tumor is cancer. Treatment may include 1 or more of the following:

  • Surgery

  • Radiation therapy

  • Chemotherapy
