Oral cancer usually occurs in the anterior (anterior) part of the mouth, and in addition to the lips which are no longer the main site of the disease, there are also common sites on the tongue and the bottom of the mouth.People who chew tobacco are likely to develop in a groove between the lips or cheeks and the soft tissue (gum) that covers the jaw (mandible).And a few cancers are unique to the salivary glands, as well as very dangerous melanomas.Although the incidence of metastatic oral cancer is insignificant compared with other metastatic oral cancers, it accounts for a small proportion of the total incidence.In the United States, it is not uncommon, but not unknown.The root of the tongue at the back of the mouth, the oropharynx (back of the throat), the amygdala column, the amygdala recess, and the amygdala itself are now more common sites, especially among young people who do not smoke.If your dentist or doctor thinks an area is suspicious, the only way to determine if it is dangerous is to biopsy the area.It’s not painful, it’s cheap, and it takes very little time.It is important to have a clear diagnosis as early as possible.Chances are your dentist or doctor will ask you to see a specialist for a biopsy.This does not cause panic, but normal communication between doctors of different specialties.More on biopsy and diagnosis
The following tests and procedures can be used to examine if you have oral caner:
Physical examination of the mouth and lips: examine the abnormal areas of the mouth and mouth.A doctor or dentist feels the entire interior of the mouth with gloved fingers and examines the mouth with a small, long-handled mirror and lamp.This includes examining the inside of the cheeks and lips;Gums;Roof and floor of mouth;The top, bottom, and sides of the tongue.There are swollen lymph nodes in the neck.Patient health habits, past illnesses, medical and dental histories will also be taken.
Endoscopy: a method of examining the internal organs and tissues of the body to examine abnormal areas.An endoscope is inserted through an incision in the skin or an opening in the body, such as the mouth.The endoscope is a thin, tubular instrument with light and lenses for observation.It may also have a tool to remove tissue or lymph node samples, which are examined under a microscope for signs of disease.
Biopsy: the removal of cells or tissue for observation under a microscope by a pathologist.If white spots are found, cells taken from the patch will also be examined under the microscope for signs of cancer.
Exfoliation: the process of collecting cells from the lips or mouth.A piece of cotton, a brush, or a small stick is used to gently scrape off the cells in the lips, tongue, mouth or throat.These cells are viewed under a microscope to see if they are abnormal.
MRI(magnetic resonance imaging): a method of using magnets, radio waves, and computers to perform a series of detailed imaging of the body’s internal regions.This process is also known as nuclear magnetic resonance imaging (NMRI).
CT scan (CAT scan): a series of detailed photographs of the human body’s internal areas from different angles.The photos were taken by a computer connected to an X-ray machine.A dye may be injected into a vein or swallowed to help the organ or tissue show more clearly.This process is also known as computed tomography, computed tomography, or computerized axial tomography.
