Oral Cancer Exam

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 the dentist critically important. Oral cancers can be of varied histologic types such as teratoma, adenocarcinoma, and melanoma. The most common type of oral cancer is 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% of oral cancers are linked with smoking, tobacco use, and excessive alcohol consumption. Dr. Carroll can provide literature and education on oral cancer prevention, making healthy 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. Carroll and your dental hygienist will carefully examine the maxillofacial and oral regions for signs of pathologic changes.
The following signs will be investigated during a routine oral cancer exam:
Oral cancer exams, diagnosis and treatment
The oral cancer examination is a completely painless process. During the visual part of the examination, Dr. Carroll will look for abnormalities and feel the face, glands, and neck for unusual bumps. Lasers that can highlight pathologic changes are also a wonderful tool for oral cancer screening. The laser can “look” below the surface for abnormal signs and lesions which would be invisible to the naked eye.
If abnormalities, lesions, leukoplakia or lumps are apparent, the dentist will implement a diagnostic impression and treatment plan. In the event that the initial treatment plan is ineffective, a biopsy of the area will be performed. The biopsy includes a clinical evaluation which will identify the precise stage and grade of the oral lesion.
Oral cancer is deemed to be 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, Dr. Carroll and your hygienist will thoroughly look for changes and any 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 Dr. Carroll or your dental hygienist.
