Oral cancer screening is a routine dental examination performed by a dentist or healthcare provider to detect signs of oral cancer or precancerous conditions in the mouth and surrounding areas. This screening is often part of regular dental exams and is an essential tool for early detection, as oral cancer can be difficult to identify in its early stages without professional help.

Why Is Oral Cancer Screening Important?

Oral cancer can develop in areas such as the lips, tongue, cheeks, gums, floor of the mouth, palate, sinuses, and throat. Early detection plays a crucial role in improving the chances of successful treatment. Unfortunately, oral cancer is often diagnosed in later stages, making it more challenging to treat. Regular oral cancer screenings are essential for catching these abnormalities early, allowing for prompt intervention and better outcomes.

What Does an Oral Cancer Screening Involve?

An oral cancer screening typically includes several key steps:

1. Visual Examination:

Your dentist will thoroughly examine the inside of your mouth, including your gums, tongue, and throat, looking for any signs of abnormal growths, sores, or changes in tissue color and texture. The dentist will also inspect your face, neck, and jaw for unusual lumps or bumps.

2. Physical Examination (Palpation):

The dentist will gently feel your jaw, neck, and under the chin to check for any lumps or swelling that could signal the presence of oral cancer. They may also examine your lymph nodes for signs of infection or cancer.

3. Inspection of the Throat and Lips:

Your dentist will check your lips and the inside of your mouth (including the roof, floor, and gums), as well as the back of your throat, for early indicators like white or red patches (leukoplakia or erythroplakia), which could be a sign of oral cancer.

4. Screening Tools (Optional):

In some cases, dentists may use specialized tools like Velscope to detect tissue changes that are not visible to the naked eye. These tools use fluorescence to spot abnormalities early on.

Signs and Symptoms Detected During an Oral Cancer Screening:

Here are some warning signs that your dentist may identify during an oral cancer screening:

• Persistent mouth sores or ulcers that don’t heal (lasting more than two weeks)

• Red or white patches inside the mouth or on the lips

• Lumps or thickened areas in the mouth, gums, or throat

• Persistent pain or tenderness in the mouth, tongue, or throat

• Difficulty swallowing, chewing, or speaking

• Unexplained bleeding in the mouth

• Numbness or loss of feeling in any part of the mouth

• A sore throat or feeling like something is stuck in the throat that doesn’t go away

Who Should Get an Oral Cancer Screening?

Adults over the age of 40 are at a higher risk for developing oral cancer and should consider regular screenings. Those with additional risk factors may require more frequent screenings:

• Tobacco users: Smoking or using smokeless tobacco significantly increases the risk of oral cancer.

• Alcohol consumption: Heavy alcohol use raises the risk of oral cancer.

• Family history of cancer: If oral cancer or other cancers run in the family, your risk may be higher.

• Human papillomavirus (HPV): Certain strains of HPV, particularly 16 and 18, are associated with an increased risk of oral and throat cancers.

• Sun exposure: Frequent sun exposure, especially on the lips, increases the risk of lip cancer.

When Should You Seek an Oral Cancer Screening?

You don’t have to wait for a scheduled dental checkup to request an oral cancer screening. If you notice any of these symptoms or changes, it’s important to get screened right away:

• Persistent mouth sore that doesn’t heal

• Unexplained pain, numbness, or tenderness in the mouth, tongue, or lips

• Difficulty moving your jaw or swallowing

• Persistent bad breath (halitosis) despite good oral hygiene

What Happens if Abnormalities Are Found?

If your dentist finds any suspicious signs during the oral cancer screening, they may recommend further tests, such as:

• Biopsy: A small tissue sample may be taken from the suspicious area and sent to a lab for analysis to check for cancer cells. A biopsy is a crucial step in determining whether a growth is malignant or benign.

• Referral to a Specialist: If necessary, the dentist may refer you to an oral surgeon or a specialist for further evaluation and testing.

What Happens After an Oral Cancer Screening?

If no abnormalities are found, you will continue with regular dental checkups (typically every six months) to maintain your oral health. If suspicious findings are identified, your dentist will guide you through the next steps, including additional testing and referrals.

Prevention and Lifestyle Tips for Oral Cancer:

To reduce the risk of oral cancer, follow these preventive measures:

• Avoid tobacco: Quit smoking or using smokeless tobacco to lower your risk.

• Limit alcohol: Reducing alcohol consumption, particularly in combination with tobacco use, can decrease your risk.

• Protect your lips from sun exposure: Use lip balm with SPF or wear a wide-brimmed hat to shield your lips from harmful UV rays.

• Maintain good oral hygiene: Brush your teeth twice a day, floss daily, and visit the dentist regularly.

• Consider the HPV vaccine: The HPV vaccine can protect against strains of the virus linked to oral cancer, and it’s typically given to preteens and teenagers.

Conclusion

Oral cancer screening is a vital part of maintaining good oral and overall health. Early detection through regular screenings can significantly increase the chances of successful treatment and reduce the impact of oral cancer.
