Understanding Oral Cancer: Causes and Risk Factors
Oral cancer refers to any cancerous growth that occurs in the mouth or throat. It can affect various parts of the oral cavity, including the lips, tongue, gums, cheeks, and roof or floor of the mouth. Like other types of cancer, oral cancer occurs when cells in the mouth or throat mutate and grow uncontrollably.
There are several common causes and risk factors associated with oral cancer. Tobacco use, including smoking cigarettes or cigars and using smokeless tobacco products like chewing tobacco or snuff, is one of the leading causes of oral cancer. Alcohol consumption is another significant risk factor, especially when combined with tobacco use.
Human papillomavirus (HPV) infection is also a known risk factor for oral cancer. HPV is a sexually transmitted infection that can cause changes in cells that lead to cancer development. Additionally, excessive sun exposure can increase the risk of lip cancer.
Why Oral Cancer Screening is Important for Everyone
Regular oral cancer screenings are essential for everyone, regardless of age or risk factors. Early detection of oral cancer can significantly improve the chances of successful treatment and survival. According to the American Cancer Society, the five-year survival rate for localized oral cancer is 84%, compared to only 39% for cases that have spread to distant parts of the body.
Screenings can help identify any abnormalities or signs of oral cancer before they become more advanced and difficult to treat. Dentists are often the first healthcare professionals to detect oral cancer during routine dental check-ups. They are trained to recognize the early signs and symptoms of oral cancer, such as red or white patches, sores that don’t heal, lumps or thickening of the skin, and difficulty swallowing or speaking.

Dentists play a crucial role in detecting oral cancer early. During routine dental check-ups, dentists perform visual exams and palpation to look for any signs of oral cancer. They examine the lips, tongue, gums, cheeks, and other parts of the mouth for any abnormalities or suspicious lesions.
Dentists are trained to recognize the early signs and symptoms of oral cancer and can refer patients for further testing if necessary. They may use advanced technologies like VELscope or OralCDx to enhance their ability to detect oral cancer. These tools can help identify abnormal tissues that may not be visible to the naked eye.
Regular dental check-ups are essential for maintaining good oral health and preventing oral diseases, including oral cancer. Dentists can provide education on oral hygiene practices, offer advice on lifestyle changes that can reduce the risk of oral cancer, and monitor patients for any changes or abnormalities during follow-up visits.
Types of Oral Cancer Screening Procedures
There are several different screening methods used to detect oral cancer. The most common method is a visual exam, where a dentist visually inspects the mouth and throat for any signs of abnormalities or suspicious lesions. They may use a tongue depressor and a light to get a better view of the oral cavity.
Palpation is another screening method used to detect oral cancer. During palpation, the dentist uses their hands to feel for any lumps, bumps, or other abnormalities in the mouth and throat. They may also examine the neck and lymph nodes for any signs of swelling or tenderness.
Advanced technologies like VELscope and OralCDx can also be used to enhance the detection of oral cancer. VELscope is a handheld device that uses a special light to detect abnormal tissues in the mouth. OralCDx is a brush biopsy system that collects cells from suspicious lesions for further analysis.
Benefits of Regular Oral Cancer Screening
Regular oral cancer screenings offer several benefits. Firstly, they provide peace of mind for individuals who may be at risk for oral cancer. By undergoing regular screenings, individuals can have confidence that their oral health is being monitored and any potential issues will be detected early.
Early detection is one of the most significant benefits of regular oral cancer screenings. When oral cancer is detected early, treatment options are more effective, and the chances of successful treatment and survival are significantly higher. Regular screenings can help identify any abnormalities or signs of oral cancer before they become more advanced and difficult to treat.
In some cases, regular oral cancer screenings can be life-saving. By detecting oral cancer early, individuals have the opportunity to receive prompt treatment and potentially prevent the spread of the disease to other parts of the body. This can greatly improve their prognosis and overall quality of life.
What to Expect During an Oral Cancer Screening Exam
During an oral cancer screening exam, individuals can expect their dentist to perform a thorough examination of their mouth and throat. The dentist will visually inspect the lips, tongue, gums, cheeks, and other parts of the mouth for any signs of abnormalities or suspicious lesions. They may use a tongue depressor and a light to get a better view of the oral cavity.
The dentist may also use their hands to feel for any lumps, bumps, or other abnormalities in the mouth and throat. They may examine the neck and lymph nodes for any signs of swelling or tenderness. If any suspicious lesions are found, the dentist may recommend further testing, such as a biopsy, to determine if they are cancerous.
It is common for individuals to have questions or concerns about oral cancer screenings. It is important to communicate any concerns or symptoms to the dentist during the screening exam. They can provide information and reassurance and address any specific concerns that individuals may have.
Early Detection of Oral Cancer: Key to Successful Treatment
