You are right. The doctor did the laryngoscopy and my throat looks normal. I still have the symptom but she says maybe the acid-blocking pills will help. She is being very thorough and will do another examination in a month. Thank you so very much for your support and expert advice.
Hi,
The symptoms of laryngeal cancer depend on the location of the tumor.Tumors in the supraglottal region above the vocal cords often cause more, but less distinct symptoms. These include:persistent sore throat,pain when swallowing,difficulty swallowing or frequent choking on food,bad breath,lumps in the neck,persistent ear pain (called referred pain; the source of the pain is not the ear) and change in voice quality.

Keeping in mind your history of acid reflux in all probability this has to do with GERD.
Your symptoms also occur only with certain food substances which also favors a diagnosis of GERD.
So I think you should hope for the best result possible i.e no cancer of larynx.
