Causes and Risk Factors for Throat Cancer

Overview

Throat cancer, also known as oropharyngeal cancer, is a type of cancer that affects the throat area. It can affect the throat, voice box, or tonsils. Throat cancer develops when the DNA of cells mutate (change), resulting in cells multiplying out of control. These cells may form a mass or tumor. Experts have identified several factors that may increase the risk of developing throat cancer. These factors include both non-modifiable risk factors (factors a person cannot change or control) and modifiable risk factors (factors a person can potentially change or control). A person may reduce their chances of developing throat cancer by changing health behaviors related to modifiable risk factors.

Non-modifiable Risk Factors (Risk Factors You Can't Change)

Non-modifiable risk factors for throat cancer are factors that cannot be changed or controlled by individuals. These risk factors include:

Age: The risk of developing throat cancer increases with age. While throat cancer can affect people of any age, it is more common in individuals who are 40 years old or older.
Sex assigned at birth: Throat cancer is more common in males than females. However, it's important to note that anyone, regardless of their sex assigned at birth, can develop throat cancer.
Genetics: Certain genetic factors can increase the risk of developing throat cancer. For example, having a family history of throat cancer or certain genetic mutations may increase the likelihood of developing the disease.
Race or ethnicity: People of certain races or ethnicities may have a higher risk of developing throat cancer. For example, Black individuals have been found to have a higher incidence of throat cancer compared to other racial or ethnic groups.

Modifiable Risk Factors (Factors You May Be Able to Change)

It is important to understand the modifiable risk factors for throat cancer, which are behaviors or conditions that can be changed or controlled to reduce the risk of developing the disease. Here are some modifiable risk factors for throat cancer:

Smoking: Tobacco smoking is the most significant risk factor for all cancers of the head and neck, including throat cancer. Regular, long-term, heavy smokers are more likely to develop throat cancer than non-smokers. Use of chewing tobacco also increases risk.
Alcohol consumption: The heavy and ongoing consumption of alcoholic drinks raises the risk of developing throat cancer. Ethanol, which is found in alcoholic beverages, is the type of alcohol that increases the risk. It's important to note that the amount of alcohol consumed over time, rather than the type of alcoholic beverage, seems to be the most important factor in raising cancer risk.
Human papillomavirus (HPV) infection: Although not the sole cause, having an HPV infection increases the risk of developing throat cancer. HPV is a common sexually transmitted infection, and certain strains of HPV are linked to an increased risk of throat cancer.
Poor nutrition and vitamin deficiencies: Having a diet lacking in fruits and vegetables, as well as overconsuming processed meats, may contribute to the development of throat cancer.
Gastroesophageal reflux disease (GERD): This condition, which involves stomach acid flowing back into the esophagus, has been linked to an increased risk of throat cancer.
Exposure to certain materials: Being exposed to substances like asbestos or acid mists produced during certain manufacturing processes can potentially contribute to throat cancer development.

If you have concerns about your risk factors for throat cancer, it's best to contact your doctor who can provide personalized advice and guidance based on your individual health history and lifestyle choices.

Reducing Risks

To prevent or reduce the chances of getting throat cancer, there are several actions a person can take to modify their risk factors. Here are some steps they can consider:

Avoid all tobacco products: Quit smoking cigarettes, cigars, or pipes. Also stop using chewing tobacco and snuff.
Moderate alcohol consumption: The general recommendation for alcohol moderation for people who drink is no more than one drink per day for women and not more than two drinks per day for men.
Get the HPV vaccine to reduce the risk of getting HPV. The recommended age range for getting the HPV vaccine is age 9 through age 45.
Practice safe sex: Reduce the risk of getting HPV and other sexually-transmitted infections by limiting the number of sexual partners and using condoms.
Wear protective gear such as a mask when working in environments with a lot of dust, smoke, or fumes.
Eat a balanced diet that includes lots of fruits and vegetables and limits processed meats and fried or salty foods.

Remember, these actions can help modify risk factors for throat cancer, but it's always a good idea to consult with a healthcare professional for personalized advice and guidance.
