Oral Cancer: How To Prevent It?

Oral cancer is the 9th most common type of cancer worldwide. Spreading to other parts of the body, oral cancers can be life-threatening. Often there are no symptoms in the early stages. If you experience any, they will often be due to pain, discomfort or bleeding. This article looks at the causes of oral cancer, their risk factors, ways to prevent it so that you can recognise them and get help if necessary.


Causes of Oral Cancer

The causes of oral cancer are not completely clear. Some sources say that it is believed that the human papilloma virus (HPV) and tobacco play a critical part in the development of this type of cancer, while others believe it is more complicated than that. The HPV virus can be transmitted through oral sex and some strains can lead to oropharyngeal cancer, which is the most common variation of oral cancer.


Symptoms of oral cancer

Oral cancer symptoms are not always obvious, which means it can be difficult to detect.

Sometimes symptoms include difficulty swallowing or pain when chewing food.

The symptoms of oral cancer may be even more subtle.

Symptoms can also include persistent sore throat or swollen gums.


What are the risk factors for oral cancer?

There are many risk factors for oral cancer. Some of the most common are tobacco use, heavy alcohol consumption, profession that exposes you to radiation, and poor immune system. Consuming large amounts of an acid called nitrate can also lead to this type of cancer.


Ways to prevent Oral Cancer

It’s not always easy to detect because symptoms like pain, discomfort and sores can be caused by other things. The best defense against oral cancer is to make sure you get your teeth checked out regularly by a dentist.


Besides, one of the most important ways is to reduce your risk of infection. This can be accomplished by avoiding alcohol and tobacco, and brushing your teeth at least twice a day. Also, avoid chewing on tobacco products. Tobacco contains a number of cancer-causing substances that increase your risk of oral cancer. These cancer-causing substances are absorbed through the lining of the mouth into your saliva and then swallowed, increasing your risk for developing oral cancer.Children with parents who smoke have an increased risk of developing oral cancer. If you smoke, it is recommended that you quit. Visit the tobacco cessation resources page for help in breaking the habit.


Also, anyone with a history of mouth cancer should have their head and neck checked regularly. If you have a family history of mouth cancer or other risk factors, your dentist will discuss what is appropriate for you personally.


Oral cancer screening is essential to early detection of any possible oral cancer. Most cases of oral cancer are found in the early stages. The Canadian Cancer Society recommends that everyone 40 years of age or older have a complete oral cancer examination as part of their regular health examination. It is recommended that you visit your dentist or physician on a regular basis to have your mouth examined and teeth cleaned.
