The definition of a tumor is a mass of abnormally growing cells. Tumors can be either benign or malignant. Benign tumors have uncontrolled cell growth, but without any invasion into normal tissues and without any spread. A tumor is called malignant (cancer) when tumor cells gain the propensity to invade tissues and spread locally as well as to distant parts of the body. In this sense, laryngeal cancer occurs when cells in the lining of the throat grow uncontrollably and form tumors that can invade normal tissues and spread to other parts of the body. 

Symptoms

Smoking is the most important risk factor for laryngeal cancer. Heavy chronic consumption of alcohol, particularly alcoholic spirits, is also significant. When combined, these two factors appear to have a synergistic effect. Some other quoted risk factors are likely, in part, to be related to prolonged alcohol and tobacco consumption. These include low socioeconomic status, male sex, and age greater than 55 years.

Allergy: A misguided reaction to foreign substances by the immune system , the body system of defense against foreign invaders, particularly pathogens (the agents of infection ). The allergic reaction is misguided in that these foreign substances are usually harmless. The substances that trigger allergy are called allergen. Examples include pollens , dust mite, molds , danders , and certain foods. People prone to allergies are said to be allergic or atopic.

But many other things can cause a hoarse voice.  One of the most common causes is acute laryngitis (inflammation of the larynx).  This usually happens due to  a cold, a chest infection or over use of the voice, such as shouting or screaming. The symptoms of laryngeal cancer depend on where the cancer develops. Since it most often develops on the vocal cords, hoarseness or other changes in the voice are common.

Causes

There is no single cause of laryngeal cancer but some factors increase the risk of developing it. Most people diagnosed with laryngeal cancer are over the age of 50. Men are more likely to be diagnosed with this disease than wome 

Tobacco: The number one cause of laryngeal cancer is chronic smoking. It has been shown that people who smoke over a prolonged period of time, whether heavy or relatively light smokers, have the greatest risk for laryngeal cancer. As smoke passes by the larynx on its way to the lungs, it can damage the cells there.
 
Heavy drinking and smoking is particularly linked to cancer above the vocal cords (the supraglottis) and the area around the vocal cords (the glottis).   Compared to non-drinkers, you have about 3 times the risk of developing cancer of the larynx if you are a heavy drinker.  Even drinking less than two drinks a day (for example two pints of beer or two large glasses of wine) gives a slightly increased risk of laryngeal cancer. 

Treatment

The doctor can describe your treatment choices and the results you can expect for each treatment option. You will want to consider how treatment may change the way you look, breathe, and talk. You and your doctor can work together to develop a treatment plan that meets your needs and personal values.

The choice of treatment depends on a number of factors, including your general health, where in the larynx the cancer began, the size of the tumor, and whether the cancer has spread.
