Welcome to the forum.
Almost certainly "various lumps and bumps" in your mouth are not due to HPV, and certainly they are not cancer. The only oral cancer known to be caused by HPV is of the back of the throat, and is almost never seen in people under 40 years old. Also, HPV of the throat, as well as cancer itself, is entirely painless. There is no chance that any of these symptoms, or your possibly inflamed lymph nodes, are due to HPV or cancer.
If these symptoms continue, see your doctor. But don't be worried about anything serious or about oral HPV.
I hope this has been helpful. Best wishes-- HHH, MD
Almost certainly you would have noticed the lump in your throat, perhaps with trouble swallowing, and would be able to see the growth -- which by 9 months might be as big as a marble. You would not miss it.
If the oral bumps continue, bring them to the attention of your doctor or dentist next time you visit either office. But really, don't worry about this. Despite all the news about it, throat cancer from HPV is really rare -- far less common than most cancers you know about (breast, lung, colon, prostate, etc, etc).
Thank you, doctor.
I know this probably sounds far-fetched, but supposing I did have back of throat/base of tongue cancer- if I'd had this for nearly 9 months, could I expect to have experienced some more noticeable symptoms by now? How long does HPV cancer generally take to progress/spread? Could it potentially spread from the throat area to the hard palate region?
These will be my last questions and I am truly grateful for your time.
Thank you for your time, Doctor. You provide an excellent service.
