I have no idea aboutthroat cancer, but in general cancer is unlikely unless you can connect to a cause, chewing tobacco and smoking comes to my mind as examples. Even these usually take a number of years of exposure.
Have you tried posting on the cancer community?
Thanks for responding. Can this be a sign of throat cancer? Any idea?
Hard for me/anyone to give you more insight than your hands-on ENT specialist. Sounds like he found a problem.
On the white tongue I wonder if the salt water may be adding to that problem, and what are you using for a " tongue cleaner" ? I can immage using a tooth brush to scrub the tongue, I have never heard of a tongue cleaner.
Be sure you get things in order, sore throat, white on tongue, anything else and see if there are any cause and effects there. Again, you doctor found a problem if you have not yet been checked to see if the cure worked, you may need a follow up visit with your ENT.
Good luck,
