A long term sore throat is one of the warning signs of cancer. This does not mean you have it, but it does mean that you should get a definitive diagnosis as to why this has persisted. More than one opinion from someone else besides your ENT that is oral cancer oriented would be worthwhile. Discolorations of the gingiva in the mouth whether bluish or with red and white coloration are also not positive indicators, and are potential causes for concern. Precancerous conditions such as leukoplakia and erythroplakia, as well as melanoma all discolor oral tissues. Please do not delay any longer in having this checked out. A simple biopsy of the area can put your mind at rest, or get you proper help if it is something that requires more serious concern and action. Do not go with one person
