A few weeks ago my dentist pointed out to me that the right tonsil was bigger than the left one. I am 31 male, nonsmoker, nondrinker. He examined my neck and said no lymph nodes were enlarged. The right tonsil does not have any ulceration and appears to be slightly larger than the other one. After I got home I started feeling a little pain once in a while in the tonsil area and in the neck. I don`t have pain anymore but the tonsil is still same as it was 3 weeks ago, same in appearance and size. My insurance just kicked in but it does nor cover any tonsil/adenoids conditions for the first 6 months. Thinking about making an appointment with ENT. I am sure everyone here will suggest exactly that.....
Tonsil at cancer is caused by HPV, Human Papilloma Virus, most of the time. It is usually not painful and looks like grey clam in the side of your throat. Tonsils are susceptible to infection and accumulation of bacteria and their waste.
Recommend best person for diagnosis is a dentist, not an ENT.
I am a dental hygienist and see this cancer occasionally.
Hope this helps even though you posted this a while ago.
