Oral, by or having to do with the mouth. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
Preview- Evidently, sixty percent of oral carcinomas are advanced by the time they are detected, and about 15 percent of patients have another cancer in a nearby area such as the larynx, esophagus, or lungs. Esophagus is the muscular tube through which food passes from the throat to the stomach. Larynx is the area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called voice box.
- It`s possible to observe, for persistent white or erythematous oral lesions, biopsy should be performed to rule out neoplastic change or cancer. Most oral cancers are squamous cell carcinomas. Tobacco and heavy alcohol use are the principal risk factors for oral cancer. Biopsy is the removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy. Cell is the individual unit that makes up the tissues of the body. All living things are made up of one or more cells. Alcohol is a chemical substance found in beer, wine, and liquor, and some medicines, mouthwashes, household products, and essential oils (scented liquid taken from plants). Alcohol contains a carbon atom attached to a hydroxyl group (a molecule made of an oxygen atom and a hydrogen atom). Squamous cell, flat cell that looks like a fish scale under a microscope. These cells cover inside and outside surfaces of the body. They are found in the tissues that form the surface of the skin, the lining of the hollow organs of the body (such as the bladder, kidney, and uterus), and the passages of the respiratory and digestive tracts. Tobacco is a plant with leaves that have high levels of the addictive chemical nicotine. The leaves may be smoked (in cigarettes, cigars, and pipes), applied to the gums (as dipping and chewing tobacco), or inhaled (as snuff). Tobacco leaves also contain many cancer-causing chemicals, and tobacco use and exposure to secondhand tobacco smoke have been linked to many types of cancer and other diseases. The scientific name is Nicotiana tabacum.
- It would seem to be apparant that, precancer and early oral cancer can be subtle and asymptomatic. Asymptomatic, having no signs or symptoms of disease.
