Throat cancer (larynx) is the most frequent tumor of head and neck. Moreover, in recent years, the incidence has increased and diagnosed more frequently, too, to a higher level in the deep part of tongue, mouth and nose.
Laryngeal cancer mainly affects men, especially after age 60, and the snuff affects their appearance and development. The smoke that the smoker inhales from his lips, passes all the way from the mouth and throat, irritating and chronically inflamed mucosa whole aerodigestive tract, to finally reach the lungs. All this is directly related to a higher incidence of throat and adjacent anatomical areas cancer.
Another factor is alcohol directly, which enhances the effect of snuff and acts as a direct irritant across the mucosa of the mouth and neck. In 95% of cases of throat cancer patients are smokers and drinkers.
Other causal factors Throat Cancer
Other factors causing this cancer are inhaling toxic environmental or occupational exposure. The most common is asbestos, also implicated in tumor lung pleura. Nickel, cement powder, aromatic hydrocarbons and sulfuric acid, among others, have also been linked to cancer of the throat. Finally, exposure to ionizing radiation, human papillomavirus and herpes, and without forgetting the inherited genetic factors may contribute to tumor appearance.
How is it diagnosed?
The cancer is detected by screening tests done by a specialist in otolaryngology. This test is known as exploratory endoscopy and is complemented by imaging (CT, Nuclear Magnetic Resonance, PET scan, ultrasound, Stroboscopy, etc.) and is diagnosed by a biopsy of the lesion.
To treat laryngeal cancer we have surgery, which involves access to the area where the tumor is located and remove it by scalpel or laser. In many cases, it must be combined transoral surgery (minimally invasive) with open surgery to remove the cervical neck, and externally tangible or tumor-associated lymph nodes.
