A soreness of the throat or a persistent cough. A persistent cough is one of the initial symptoms of throat cancer. If the cough becomes chronic, it could indicate, instead, a cancer of the lung or of some other region of the body, including the thyroid or the larynx. A cough that goes away in a little while is nothing more than a mild respiratory disorder, such as a cold. However, a cough that is chronic and persists for a long time is definitely a symptom of something more serious.
Issues with breathing. Research studies done in the United Kingdom found that between half to nearly three quarters of all those who suffer from throat cancer will have serious issues with their breathing. If the sound that you make while breathing changes to a considerable extent from your norm, and especially if it is high pitched or extremely loud, it could be a symptom of a serious condition. Problems in breathing and noisy breathing occur when a cancer of the larynx constricts the voice box, or else the vocal cords themselves.
A tenderness or soreness in the throat and difficulty in eating or drinking. A sore throat is a very common symptom of throat cancer. There will also be the sensation of having a foreign object ‘somewhere in the throat’. Foods that are large or chunky may show extreme difficulty in going down, and it might become positively painful to ingest certain types of food, or even to drink. This is obviously due to the growth of the tumor in the throat, and these problems will be exacerbated as the tumor grows larger. Please note that a sore throat can simply be the sign of a minor respiratory infection, but all minor respiratory infections can be treated easily and will disappear in a very little while, while a sore throat indicative of cancer will be chronic.
