Larynx Cancer Diagnosis
Laryngeal cancer results when the cell cycle in the tissues of the larynx goes awry. Normally, new cells are created to replace old ones at a steady rate, however, in cancer new cells are created when they are not needed and this can result in a malignant growth or tumor. Cancer is a life-threatening ailment when not diagnosed early enough. Untreated, the malignant cells can proliferate into the bloodstream or lymphatic system and travel to other parts of the body in a process called metastasis.
Diagnosis:
There are many ways (or steps) in which cancer is diagnosed:
~ Physical examination - during this procedure, a physician will feel the throat for any abnormal lumps or growths. Using a tongue depressor, the doctor may also examine the back of the throat.
~ Indirect laryngoscopy - this procedure entails the physician checking the vocal folds and larynx for abnormal growths using a long-handled mirror.
~ Direct larygoscopy - here, a doctor inserts a long, lighted tube, called a laryngoscope, directly down the nose or throat in order to see more obscure parts of the larynx. A sedative and/or anesthetic is used to ease discomfort.
~ CT scan - this is a test in which an x-ray machine takes a closer look at the larynx. Typically, a special dye is injected into the area to help radiologists see the larynx.
~ Biopsy - Using a laryngoscope, a physician will extract a piece of any abnormal growth tissue and then send it to a pathology lab. A pathologist will then examine the cells for cancer. This test will generally confirm either a malignant or benign tumor.
