What are the symptoms of larynx cancer?

specific symptoms of larynx cancer, also known as laryngeal and voice box cancer, depend on the location of the tumor. There are three primary parts of the larynx in which cancer can grow: subglottis, supraglottis and glottis. Most symptoms will be in the throat. The individual may also notice lumps, swelling and sore throat. Some patients have difficulty swallowing and atypical weight loss. There may also be a bad breath and a persistent cough that could produce blood, and breathing may sound unusually high. Some of the symptoms of larynx cancer that the doctor may discover during the initial test include one or more lump outside the neck, swelling in the neck and bloody mucus. Physical examination of the tunic inside can also show signs of disease.

If the physical test indicates the symptoms of larynx cancer, most doctors try to make a firm diagnosis through a series of intensivelytested tests. It is common for the doctor to first perform indirect laryngoscopy, in which a long handle mirror is inserted into the neck to make better views of the area. For the appropriate view, direct laryngoscopy may be necessary in which the illuminated tube is inserted into the neck.

Many doctors will also scan cranial computer tomography (CT), scanning by magnetic resonance (MRI) or biopsy to diagnose. MRI and CT scans can provide more detailed information about potential throat growths through X -ray images that are displayed on the computer screen. Biopsy involves removing the sample of the tissue from the neck to test the NCER cabuns. This final method is usually the most effective way to make a definitive diagnosis.

larynx cancer most often begins in glottis, which is the location of real vocal chords, also known as vocal folds. This is the least common at the bottom of the larynx known as subglottis.Some cases also start in Supraglottis, which is the placement of epiglottis, a flap that protects the entrance to the larynx.
