Introduction

Oral cancer, also known as mouth cancer, is a type of cancer that occurs in any part of the mouth, including the lips, tongue, gums, inner lining of the cheeks and the roof or floor of the mouth. It is classified as a head and neck cancer, and like many other types of cancer, it can be life-threatening, if not diagnosed and treated early. Oral cancer is an important health concern because it affects basic functions such as eating, speaking and breathing.

Historically, oral cancer has been linked to certain lifestyle factors, such as tobacco and alcohol use. However, recent developments have shown that human papillomavirus (HPV) infection also plays a significant role in some cases. Advances in treatment, including surgical techniques, targeted therapies and immunotherapy, have provided new hope for better outcomes and quality of life for patients with oral cancer.

Statistics

Oral cancer is one of the more common forms of cancer globally. In the United States alone, approximately 54,000 new cases are diagnosed annually, with around 11,000 deaths each year. Oral cancer is more prevalent in men than women, with men being twice as likely to develop the disease. It is also more common in people over the age of 50. The 5-year survival rate for oral cancer is around 65%, but this varies significantly depending on the stage at which the cancer is diagnosed. Early detection greatly improves the prognosis, with survival rates as high as 85% for localized cancer.

Risk Factors and Prevention

a. Known Risk Factors

Several factors increase the risk of developing oral cancer. The most significant risk factors include the use of tobacco products, such as cigarettes, cigars, pipes and smokeless tobacco. Heavy alcohol consumption is another major risk factor, especially when combined with tobacco use. Infection with HPV, particularly HPV type 16, has been increasingly recognized as a risk factor for oral cancer, particularly in younger individuals.

Other risk factors include prolonged exposure to the sun (which can lead to lip cancer), a diet low in fruits and vegetables, and a weakened immune system. Genetics also play a role, as individuals with a family history of cancer may be at an increased risk.

b. Prevention

While not all cases of oral cancer can be prevented, there are steps that can be taken to reduce the risk. Avoiding tobacco products and limiting alcohol consumption are the most effective ways to lower the risk of developing oral cancer. Vaccination against HPV can also help reduce the risk, particularly when administered before exposure to the virus. Maintaining good oral hygiene and a balanced diet rich in fruits and vegetables can also contribute to a lower risk of oral cancer. Regular dental check-ups are crucial, as dentists can often spot early signs of oral cancer.

Screening

There is no standard screening test for oral cancer for individuals without symptoms. However, routine dental check-ups play a key role in early detection. During a dental exam, the dentist will check for any abnormalities in the mouth, such as sores, lumps, or discolored patches. If anything suspicious is found, a biopsy may be performed to determine if cancer cells are present.

Symptoms and Early Warning Signs

Symptoms of oral cancer can vary, but common signs include a persistent sore or ulcer in the mouth that does not heal, a lump or thickening in the cheek, white or red patches on the gums, tongue, or lining of the mouth and difficulty chewing or swallowing. Other symptoms may include numbness in the tongue or other areas of the mouth, a sore throat that doesn’t go away, and changes in the voice.

It is important to note that these symptoms can also be caused by less serious conditions, such as infections. However, if any of these symptoms persist for more than two weeks, it is essential to seek medical attention for further evaluation.
