The larynx is located just after the junction of the pharynx. It is

swallowed substances from returning;
being an integral part of the airways;
of vocal sounds.
The pharynx is a fibromuscular tube that extends from the back of the
nasal cavity and mouth to the esophagus. It participates in four main functions:
All these functions are
possible thanks to thousands and thousands of cells that work synergistically in the throat. Every day,
thousands of these cells naturally die (self-cell destruction or apoptosis) to be replaced by new healthy cells.
Throat cancer occurs when there is abnormal and anomic cell proliferation in the tissue of the throat.
Although all the causes of
throat cancer are not identified, its primary factor is smoking. The risk is even higher when smoking is
associated with heavy alcohol consumption, another causative factor for throat cancer. It is estimated that
heavy smokers have about 20 times more chance to die from cancer of the throat than non
Tobacco contains toxic
substances. Once in the aerodigestive
tract, tobacco smoke and the harmful
substances directly alter the lining of the throat by changing the morphology of the tissue. Smoking increases
the air temperature inside the larynx to 42 ° C. Persistence in this practice will lead to microdamage in the
throat tissue, which sooner or later turn into cancer.
