Hi and welcome. Throat or esophageal cancer is very rare and is found in >55age,smokers and alcoholic.
Your difficulties can be caused by anxiety
or by some organic pathology. Commonly such symtoms are caused by gastritis
,GERD or hiatal hernia
. I suggest to change your dietary habbits first. Follow some of antiacid diets,avoid alcoohl, coffee, fats and smoking
.Eat more milk products and green. There ara also some medicines which can be helpful. Consult your GP about this.
If this persist or progress you should do gastroscopy to evaluate your condition.
Wish you good health.
