Oral cancer is a type of cancer that occurs in the mouth or throat. It typically starts in the cells lining the mouth, tongue, or lips. Risk factors for oral cancer include tobacco use, heavy alcohol consumption, and human papillomavirus (HPV) infection. Symptoms of oral cancer can include persistent mouth sores, swelling, numbness, or difficulty swallowing. Early detection and treatment are important for improving the prognosis of oral cancer. Treatment may involve surgery, radiation therapy, chemotherapy, or a combination of these approaches. Regular dental check-ups and self-examinations can help in the early detection of oral cancer which can consult Dr Nima Arafati in Balwyn Dental Practice.

Visual examination
During a dental examination, your dentist will conduct a visual examination to check for any signs of oral cancer. This includes inspecting your lips and face for any abnormalities or changes in color, texture, or symmetry. The dentist will also observe your oral cavity, looking for any red or white patches. Additionally, they will examine your tongue and the floor of your mouth to check for any irregularities or lesions.
Physical examination
In addition to the visual examination, your dentist will perform a physical examination of your oral cavity. This involves palpating (feeling) the inside of your mouth to detect any lumps, bumps, or abnormalities. By carefully feeling the tissues, your dentist can identify any areas of concern that may warrant further investigation. Furthermore, they will assess the lymph nodes in your neck to check for any enlarged or tender nodes, which could be a potential indication of oral cancer or its spread.
Medical history and risk factors
To gain a comprehensive understanding of your oral health, your dentist will discuss risk factors for oral cancer. They will inquire about your personal and family history of cancer, including any instances of oral cancer. It is crucial to provide accurate information about any previous cancer diagnoses, as well as family history of cancer. Additionally, your dentist will evaluate your lifestyle habits, including tobacco and alcohol use.
Diagnostic tests
If your dentist identifies any suspicious areas during the visual and physical examinations, they may recommend further diagnostic tests to confirm or rule out oral cancer. Some common tests for oral cancer include an oral brush biopsy, where a sample of cells is collected from the suspicious area for microscopic examination. Toluidine blue staining may also be used, which involves applying a dye to the tissues to help identify abnormal cells. Fluorescence visualization and salivary tests can also aid in the detection and diagnosis of oral cancer. In some cases, a CT scan or an MRI scan may be required to assess the extent and spread of the disease.
Use of specialized equipment
To facilitate a thorough examination, your dentist may utilize specialized equipment. This includes a mirror and light to visualize hard-to-reach areas of the oral cavity. The mirror allows for a better view of the back of the mouth and throat, while the light helps to illuminate any potential abnormalities. Your dentist will also wear sterile gloves during the examination to ensure hygiene and prevent the spread of infections. A tongue depressor may be used to hold the tongue down and provide better access to the back of the mouth. Additionally, a head and neck examination may be performed to assess the overall health of these areas. In some cases, mouth rinses with dye may be used to aid in the detection of abnormal cells.
Early detection signs
It is essential to be aware of the early detection signs of oral cancer and report them to your dentist promptly. Persistent mouth sores that do not heal within a reasonable time frame should be evaluated. Any white or red patches on the lips, gums, tongue, or other areas inside the mouth should not be ignored. Unexplained bleeding from the mouth or gums, difficulty swallowing or chewing, as well as numbness or pain in the mouth or lips, should also be brought to the attention of your dentist. Finally, any unexplained swelling or lumps in the mouth or neck should be examined thoroughly.
Symptoms to report
In addition to the early detection signs, there are specific symptoms that warrant reporting to your dentist. Persistent mouth pain that does not resolve or is impacting your daily activities should be discussed with your dentist. Loose teeth or changes in how your dentures fit could be indicative of underlying issues, including oral cancer. Hoarseness or persistent throat soreness, unrelated to a common cold or viral infection, should also be reported. Furthermore, if you experience ear pain without any apparent ear infection, it may be related to oral health concerns and should be mentioned to your dentist.

Special considerations for high-risk individuals
Certain individuals have a higher risk of developing oral cancer, and therefore, require special consideration during dental check-ups. Tobacco users, including those who smoke or use smokeless tobacco, are at an increased risk and should be monitored closely by their dentist. Heavy alcohol consumers, particularly those who combine alcohol with tobacco use, are also at a higher risk. Excessive sun exposure to the lips, as well as infection with the human papillomavirus (HPV), can contribute to the development of oral cancer. Lastly, individuals with weakened immune systems, such as those with HIV/AIDS or undergoing certain medical treatments, also face a higher risk.
Follow-up screenings
Regular dental check-ups play a vital role in oral cancer prevention and early detection. Your dentist will likely recommend routine screenings to monitor your oral health and detect any potential changes or abnormalities. In addition to professional screenings, it is essential to perform self-examinations at home regularly. Becoming familiar with the normal appearance of your mouth can help detect changes early, leading to timely evaluation and treatment by specialists if needed.
Educating patients about oral cancer
Dentists are dedicated to promoting oral health and preventing oral cancer. As part of their role, they educate patients about the risks and prevention of oral cancer. Your dentist may discuss the various risk factors associated with oral cancer, including tobacco and alcohol use, HPV infection, and excessive sun exposure. Emphasizing the importance of early detection, your dentist will stress the significance of regular dental check-ups and self-examinations. They may provide you with educational resources and support materials to facilitate a proactive approach to your oral health.
In conclusion, dentists play a crucial role in the early detection and prevention of oral cancer. By conducting comprehensive examinations, including visual and physical assessments, and considering medical history and risk factors, dentists can identify potential signs of oral cancer. Utilizing specialized equipment and conducting diagnostic tests when necessary, they can further evaluate suspicious areas. Prompt reporting of symptoms and regular follow-up screenings are essential, especially for high-risk individuals. By educating patients about oral cancer and promoting self-examinations, dentists empower individuals to take an active role in their oral health. Together, dentists and patients can work towards preventing oral cancer and ensuring early detection for better treatment outcomes.
