- laryngeal cancer
Laryngeal cancer, cancer that forms in tissues of the larynx (area of the throat that contains the vocal cords and is used for breathing, swallowing, and talking). Most laryngeal cancers are squamous cell carcinomas (cancer that begins in flat cells lining the larynx). Laryngeal, having to do with the larynx. 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- It`s been discovered that, laryngeal cancer is the growth of malignant cells in the larynx (also known as the voice box), an organ composed of the vocal cords and a structure known as the epiglottis, a flap of tissue that prevents food from entering the airway while you swallow. The larynx is located between the pharynx, or throat, and the trachea (the windpipe). Tissue is a group or layer of cells that work together to perform a specific function. Pharynx is the hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). The pharynx is about 5 inches long, depending on body size. Also called throat. Malignant, cancerous. Malignant cells can invade and destroy nearby tissue and spread to other parts of the body. Epiglottis is the flap that covers the trachea during swallowing so that food does not enter the lungs. Trachea is the airway that leads from the larynx (voice box) to the bronchi (large airways that lead to the lungs). Also called windpipe. Voice box is the area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called larynx. Organ is a part of the body that performs a specific function. For example, the heart is an organ. Larynx is the area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called voice box. Throat is the hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). The throat is about 5 inches long, depending on body size. Also called pharynx.
- It might seem to be apparant that, over 90 percent of laryngeal cancers are a type of cancer called squamous cell carcinoma (SCCA), and over 95 percent of patients with laryngeal SCCA are smokers. Smoking contributes to cancer development by causing mutations or changes in genes, impairing clearance of carcinogens from the respiratory tract, and decreasing the bodys immune response. Squamous cell carcinoma, cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. Squamous cells are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the passages of the respiratory and digestive tracts. Also called epidermoid carcinoma. 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. Response is in medicine, an improvement related to treatment. Respiratory tract is the organs that are involved in breathing. These include the nose, throat, larynx, trachea, bronchi, and lungs. Also called respiratory system. Immune response is the activity of the immune system against foreign substances (antigens). Carcinoma, cancer that begins in the skin or in tissues that line or cover internal organs.
- It could seem apparant that, laryngeal cancer is not as well known by the general public as some other types of cancer, yet it is not a rare disease. The American Cancer Society (ACS) estimates that in 2012 there will be about 12,360 new cases of laryngeal cancer (9,840 men and 2,520 women) and about 3,650 deaths (2,880 men and 770 women).Even for survivors, the consequences of laryngeal cancer can be severe with respect to voice, breathing, or swallowing.
