thank you for your reply, very clear and complete. because of my ignorance I got into a bigger problem than myself, of which I knew nothing completely.
to date I have exaggerated otorhinolaryngology visits from a hospital primary, the last 4 months ago. I lament a swollen tonsil (with a crypt I had even before the report at risk) but now it's got worse, I have had these problems for 7 months and a swollen neck lymph node detected with MRI, "reactive" for 7 months. then I noticed that I have a whiter tongue than usual and even if I clean it with a toothbrush, it is often "dirty". the otolaryngologist who visited me told me you are calm that the lymph node is deflated but after 4 months it is still there.
I went to an oncologist gynecologist, I did peniscopy with acid, nothing significant. only initial warts say, to be cured with creams and supplements. from him I also did two oral and penile tampons, called HPV TEST in practice they are sticks rubbed on the affected area and then made to analyze in molecular biology. negative results. this gives me some relief in spite of the symptoms that persist, but I don't actually know what reliability they have, are you not aware of them? next week I will go to an otorino, maybe a specialist for cancer, not if I can get a biopsy, I hope so. but I would also like to understand how invasive it is as an exam ... thanks to everyone and good luck!
