Welcome back to the forum. In asking the same question on the community forum, you say you previously asked a question in this forum about oral HPV and cancer, but I can't find anything under your current username. Can you provide a link to that previous thread?
Just yesterday I answered a question on the same topic, in response to the Michael Douglas media stories, and it includes links to two other threads. Please take a look:
To your specific questions are:
1) Your symptoms have nothing to do with HPV, which doesn't cause sore throat.
2) "Lesion" just means any visible abnormality -- sore, bump, tumor, etc. Pharyngeal cancer would usually start as a visible tumor. Almost all cases occur in people older than you (generally age 40 to 50 or more). Your risk for HPV related throat cancer is very low, and if it ever were to happen, it's likely many years in the future.
3) I cannot comment. I have no idea how long Mr. Douglas had his cancer before it was diagnosed.
4) HPV is rarely if ever transmitted from mouth to genitals. You are no more at risk for having HPV, either genital or oral, than most sexually active men. With a moderate number of past sex partners, you can be sure you have had one or more genital HPV infections and perhaps (but not necessarily) oral HPV as well. However, at your age it is likely that any HPV infections you had have long since been cleared by your immune system. Any partners you have now or may have in the future are at low risk of catching HPV from you, by either from genital or oral sex, and no higher risk than from the average male partner your age.
The reasons behind these answers should be overed in the other threads, but let me know if anything remains unclear after you have read them.
