HI, thanks for using healthcare magic
Your concern is understandable.
Cancer of the throat is associated with difficulty swallowing, change in voice,
sore throat,
unexplained weight loss, bleeding through the mouth or nose,
chronic cough and swelling of the eyes , jaw, throat or neck.
If the swollen gland that you are referring to is a lymph node then there are different possible causes for an increased size.
Lymph node enlargement can occur due to any infectious or inflammatory process.
It can also enlarge in more serious conditions such as cancer.
It is possible that your symptoms are related to an infection of the throat or ear but when you visit the ENT you would be able to get more information.
In terms of prognosis of
throat cancer , it depends on the stage of the disease. If it is caught at an early stage then the survival chances are higher.
It would be best to stop
smoking as it is associated with a wide range of possible complications.
I hope this helps
