Causes

Tobacco Usage
This is the strongest risk factor for developing throat cancer. Tobacco that taken through mouth by chewed or smoked, increased the risk over time. It often takes longer time to get cancer but children who use chewing tobacco have gotten mouth cancer. The more the tobacco used, the higher the chance to get throat or mouth cancer. When the use is stopped, the risk declines almost to normal over a 5 to 10 years period. Not only the users of tobacco, people around the tobacco users will have a higher risk of having throat cancer too compare to others. They expose to second hand smoke in long term period increase the risk of developing this disease.

Alcohol Usage
Alcohol is another strongest risk factor after tobacco. Wine can raise the rise very slightly, but frequent use of alcohol will increase the risk of having throat cancer. The risk will be multiplied if a person use both tobacco and alcohol together. People who smoke and drink are most likely to get throat cancer than the people without the habit.  Like tobacco, if a person stop the frequent use of alcohol, he or she might lower their cancer risk.

Diet
Risk of having throat cancer will rise if a person does not practice a healthy eating habits. Poor eating habits causes lack of certain vitamins is part of the reason for the increased risk of throat cancer among the people.

Genetics Factors
Family members who have a background of having throat cancer may increase the risk of having throat cancer. Genes might be inherited and other family members also have the risk of getting this disease.


Work Hazards
People who spends a lot of time working outdoor, such as workers are more likely to have cancer. They have long and intense exposure to sunlight, wood dust, paint fumes and certain chemicals. For example, excessive exposure of UV light will causes cells to undergo mutation and causes throat cancer.


Oral Sex
Recently, a study show that a virus spread during oral sex and causes throat cancer in people under 50. Human Papilloma Virus can spread through unprotected sex and this cancer can mostly found in man.

Virus Infection
The main virus that causes throat cancer is Human Papilloma Virus Type 16. This virus can lead to increased cell growth and division. Moreover, findings indicate this type of cancer is much more prevalent in men than in woman. Besides that, another virus that causes this disease is Epstein-Barr virus. This virus can be found in almost all nasopharyngeal cancer (NPC) and most patients with (NPC) have evidence of infection by this virus in their blood.

Gender
This cancer can mostly found in men as compared to women. These cancers are about 4 times more common in men than in women. However, the risk for women to get this disease gradually increased as the number of women smokers rise.

Age
This disease are not common among the young people. This is because the cancerous cells need time to grow. More than half of the people with these cancer are over 65 years old when the cancers are first found.
