Oral Cancer Screening

The most common screening method involves a visual examination of the mouth by a dentist or other health care professional. They will look for any red or white patches, lumps or sores inside your mouth.

Some cancers never cause symptoms or become life-threatening. However, if they are found by a screening test, they may be treated. 강남임플란트 This is called overdiagnosis.

Screening Procedures

The conventional test applied in most screening studies and programs is a systematic visual inspection and palpation of the oral cavity under bright light to detect abnormal findings that raise an index of suspicion for oral cancer or OPMDs. Some programs use mobile phones to transmit clinical images deemed screen-positive by PHCWs to an expert for quick consultation.

Often, people with early-stage oral squamous cell carcinoma (OSCC) or precancerous cells will not have any symptoms. This is why it is important to check the mouth, lips, throat, and neck for changes every month, especially for those who smoke or consume alcohol.

Exfoliation

Many cancers of the oral cavity and throat are caused by the human papilloma virus (HPV). The risk is higher for people who smoke or have used tobacco in the past. It is also higher in those who regularly consume alcohol. The cancers may appear as sores, white or red patches in the mouth and neck, or lumps.

A quick and painless screening is possible by a dentist using the VELscope system. This device uses bright blue light to show problem areas that are invisible to the naked eye. Healthy tissue shows up green and any problems become very visible.

During a dental exam, your dental professional will look at the inside of your mouth and feel around with gloved hands. They will pay particular attention to the lips, cheeks and jaws for a lumpy appearance, and the floor of the mouth for sores or white patches.

Fluoride Treatment

A person with oral cancer that is caught in the early stages has a very high survival rate. But unfortunately most oral cancers aren’t diagnosed until they are in the advanced stages. This is why prevention, screening and early treatment are so important.

Dental professionals and doctors can often detect pre-cancerous or cancerous cells in the mouth, or oral cavity, during a routine checkup. The oral cavity consists of the tongue, lips, gums, palate and inside lining of the cheeks. Cancer can also form in the pharynx, which is the upper throat behind the nose.

Generally, healthcare professionals use a dye (toluidine blue) or a fluorescent light test to help spot abnormal tissue. They also recommend that patients do a self-examination once a month to look for anything out of the ordinary.

Toxicity Testing

Using the toluidine blue test, dentists can identify precancerous and cancerous cells in your mouth. This is important because cancers detected at an early stage are much easier to treat, and have higher survival rates.

Unfortunately, not all cancers found at an early stage will have a positive outcome. Some will never cause symptoms or become life threatening. It is possible that these cancers will be found by screening tests, leading to overdiagnosis.

Scientists study screening tests to find ones that have the fewest harms and most benefits. They also look at the natural history of oral cancers and OPMDs to understand how a screening program might reduce the risk of advanced disease. The natural history of these diseases is complex and varies from person to person.

Biopsies

A biopsy is a medical procedure that involves taking tissue from the mouth or lymph nodes and examining it under a microscope. The purpose of biopsies is to diagnose cancer and other diseases, allowing treatment planning.

Your healthcare provider may coat areas that are likely to be cancerous with a special dye, like toluidine blue. They can also feel (palpate) for lumps and bumps.

In addition to traditional tissue biopsy, there are other methods for obtaining a sample, including exfoliative cytology and liquid biopsy. These involve brushing, scraping or sucking cells off the surface of a lesion. The samples are then sent to a laboratory for analysis.
