Transcript of Laryngeal Cancer

Laryngeal Cancer The larynx has three main parts:

Top: The top part of the larynx is the supraglottis.
Middle: The middle part is the glottis. Your vocal cords are in this part.
Bottom: The bottom part is the subglottis. It connects to the windpipe (trachea). Your larynx opens or closes to allow you to breathe, talk, or swallow:

Breathing: When you hold your breath, your vocal cords shut tightly. When you let out your breath or breathe in, your vocal cords relax and open.
Talking: Your larynx makes the sound of your voice. When you talk, your vocal cords tighten and move closer together. Air from your lungs is forced between the cords and makes them vibrate. The vibration makes the sound. Your tongue, lips, and teeth form this sound into words.
Swallowing: Your larynx protects your lungs from food and liquid. When you swallow, a flap called the epiglottis covers the opening of your larynx to keep food and liquid out of your lungs. The picture below shows how food or liquid passes through the esophagus on its way from the mouth to the stomach. Abnormal (high-pitched) breathing sounds


Coughing up blood

Difficulty swallowing

Hoarseness that does not get better in 1 - 2 weeks

Neck pain

Sore throat that does not get better in 1 - 2 weeks, even with antibiotics

Swelling or lumps in the neck

Unintentional weight loss Symptoms Where is it? Surgery People who smoke or otherwise use tobacco are at risk of developing throat cancer.
Excessive alcohol use also increases risk. Smoking and drinking alcohol combined lead to an increased risk for throat cancers.
Most cancers of the throat develop in adults older than 50. Men are 10 times more likely than women to develop throat cancers Who's At Risk? Biopsy of tissue to confirm the presence of a cancerous tumor

Cranial CT scan

Cranial MRI

Laryngoscopy Tests I could Take? What Are They? A biopsy is the removal of a small piece of tissue for laboratory examination. A biopsy is most often done to examine tissue for disease. A magnetic resonance imaging (MRI) scan of the head is a noninvasive method to create detailed pictures of the brain and surrounding nerve tissues.

Unlike x-rays and computed tomographic (CT) scans, which use radiation, MRI uses powerful magnets and radio waves. Signals from the magnetic field bounce off your body and are sent to a computer, where they are turned into images. Different types of tissues send back different signals. A cranial computed tomography (CT) scan uses many x-rays to create pictures of the head, including the skull, brain, eye sockets, and sinuses. Laryngoscopy is examination of the larynx (voice box) using a small mirror held just below the back of your palate, or a rigid or flexible viewing tube called a laryngoscope placed in your mouth. IF I HAVE IT>
THEN WHAT? The goal of treatment is to completely remove the cancer and prevent it from spreading to other parts of the body.

When the tumor is small, either surgery or radiation therapy alone can be used to remove the tumor.

When the tumor is larger or has spread to lymph nodes in the neck, a combination of radiation and chemotherapy is often used to preserve the voice box.

Some patients need surgery to remove the tumor, including all or part of the vocal cords (laryngectomy). If you have a laryngectomy, you can learn other ways to speak with speech therapy.

Many patients also need swallowing therapy after treatment to help them adjust to the changes in the structure of the throat Treatment Throat cancers can be cured in 90% of patients if detected early. If the cancer has spread to surrounding tissues or lymph nodes in the neck, 50 - 60% of patients can be cured. If the cancer has spread (metastasized) to parts of the body outside the head and neck, the cancer is not curable and treatment is aimed at prolonging and improving quality of life.

After treatment, patients generally need therapy to help with speech and swallowing. A small percentage of patients (5%) will not be able to swallow and will need to be fed through a feeding tube Expectations Video Bibliography
