According to research conducted by the American Cancer society, more than 30,000 cases of oral cancer are diagnosed each year. More than 7,000 of these cases result in the death of the patient. The good news is that oral cancer can easily be diagnosed with an annual oral cancer exam, and effectively treated when caught in its earliest stages.
Oral cancer is a pathologic process, which begins with an asymptomatic stage during which the usual cancer signs may not be readily noticeable. This makes the oral cancer examinations performed by both our hygienist and Dr. Atkins critically important. Oral cancers can be of varied histologic types such as teratoma, adenocarcinoma, and melanoma. The most common type of oral cancer is the malignant squamous cell carcinoma. This oral cancer type usually originates in lip and mouth tissues.
There are many different places in the oral cavity and maxillofacial region in which oral cancers commonly occur, including:
Reasons for oral cancer examinations
It is important to note that around 75 percent of oral cancers are linked with modifiable behaviors such as smoking, tobacco use, and excessive alcohol consumption. Dr. Atkins can provide literature and education on making lifestyle changes and smoking cessation.
When oral cancer is diagnosed in its earliest stages, treatment is generally very effective. Any noticeable abnormalities in the tongue, gums, mouth, or surrounding area should be evaluated by a health professional as quickly as possible. During the oral cancer exam, Dr. Atkins and our hygienist will be scrutinizing the maxillofacial and oral regions carefully for signs of pathologic changes. When Dr. Atkins asks you to “stick out your tongue,” he’s able to look more carefully at areas that can “hide” problems.
The following signs will be investigated during a routine oral cancer exam:
Red patches and sores – Red patches on the floor of the mouth, the front and sides of the tongue, white or pink patches which fail to heal and slow healing sores that bleed easily can be indicative of pathologic (cancerous) changes.
Leukoplakia – This is a hardened white or gray, slightly raised lesion that can appear anywhere inside the mouth. Leukoplakia can be cancerous, or may become cancerous if treatment is not sought.
Lumps – Soreness, lumps or the general thickening of tissue anywhere in the throat or mouth can signal pathological problems.
Oral cancer exams, diagnosis and treatment
The oral cancer examination is a completely painless process. During the visual part of the examination, Dr. Atkins will look for abnormality and feel the face, glands, and neck for unusual bumps. Lasers that can highlight pathologic changes are also a wonderful tool for oral cancer checks. The laser can “look” below the surface for abnormal signs and lesions that would be invisible to the naked eye.
If abnormalities, lesions, leukoplakia, or lumps are apparent, Dr. Atkins will usually send you over to the oral surgeon for a closer look. If the oral surgeon wants to be sure, he will perform a biopsy of the area. The biopsy includes a clinical evaluation that will identify the precise stage and grade of the oral lesion.
Oral cancer is deemed present when the basement membrane of the epithelium has been broken. Malignant types of cancer can readily spread to other places in the oral and maxillofacial regions, posing additional secondary threats. Treatment methods vary according to the precise diagnosis, but may include excision, radiation therapy, and chemotherapy.
During bi-annual check-ups, the dentist and hygienist will thoroughly look for changes and lesions in the mouth, but a dedicated comprehensive oral cancer screening should be performed at least once each year.
If you have any questions or concerns about oral cancer, please ask your Dr. Atkins or our dental hygienist.
