(Ringing in the Ears)
Tinnitus – Definition
Tinnitus is the perception of abnormal ear or head noises. Tinnitus is unpleasant enough itself. It is also sometimes a symptom of other problems, including hearing loss, tumors, and narrowing of the blood vessels.
Noises may be high pitched and “ringing,” or sound more like a clicking. Some tinnitus is pulsatile. This means that it may be caused by the flow of blood that accompanies each heartbeat. This type of tinnitus is a result of the narrowing of the blood vessels.

Throat cancer – Definition
Throat cancer is a disease in which cancer cells grow in an abnormal way in the throat. The throat is the hollow tube that runs from behind the nose and mouth, down the neck, to the opening of the esophagus and windpipe.
Cancer occurs when cells in the body (in this case throat cells) divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissues and spread to other parts of the body. A benign tumor usually does not invade or spread.
