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.
