Since the 50s, malignant tumors of pharynx and larynx are very common, especially in males (85% of cases). They can be prevented by avoiding snuff and performing early explorations.
The pharynx and larynx cancer is related to alcohol and snuff. In the case of cigarettes, the ratio is in the combustion of the tar follows. A kilo of snuff (50 packages) occurs between 50 and 60 grams of tar. In the case of alcohol, it acts as a local irritant and can solubilize carcinogens, enhancing their effect.
Another cause is the presence and participation of the human papilloma virus.
Initial symptoms are difficulty swallowing and pain, which may radiate to the ear. In the case of tumors of the pharynx, not usually altered voice, while laryngeal tumors frequently hoarseness and voice changes (hoarseness) occurs, caused by alteration in the vocal cords. If the tumor grows obstructs the airway difficult breathing (dyspnea), sometimes even bleeding in the mouth. These tumors often cause glands in the neck.
The diagnosis is made through an exploration of the mouth, pharynx and larynx, and endoscopy latter. Progressive and persistent hoarseness and neck masses, an exploration endoscopy was also performed.
Treatment may consist of surgery, chemotherapy or radiotherapy. In recent years surgery has advanced significantly, allowing more precise treatments that avoid mutilations. Currently, the greatest healing results are obtained with surgery, either radical or partial (open or endoscopic, which in turn may be conventional, laser or robotics).
