Hi sir , in my opinion all your symptoms of persisting sore throat
, mild cough, chest pain is suggestive gastritis or acid reflux
Ifvi were your treating doctor.
I would advise you to stop drinking first, then prescribe anti reflux drugs for 4 weeks and see how you respond.
U can continue all other medications.
Regarding throat cancer
, sore throat, difficulty in swallowing, painful swallowing, change of voice, breathing difficulties, sudden weight loss
, neck swelling all these are suggestive of cancer.
Patient cant detect cancer, it has to be clinically evalueted by doctor.
