Thanks for the query to H.C.M. Forum.
From last 5 months , you are feeling , that something is stuck in your throat.
2nd symptom is dryness in throat.
You yourself answered that if it would have cancer then wouldn't it had been worse.
Your answer is correct.
It is not cancer.
You haven't mentioned your age and gender as these two are very important.
Two possibilities are there,
, if your blood pressure is very high particularly diastolic ( lower B P ) than there are chances that you feel something is stuck in throat.
, dryness of throat is very common but in diabetes Hypertension may be associated .
3 This may be due to hyper acidity chronic .
Consult a physician and get in his opinion and blood examination as well.
Hope for the best.
