You have no worries about oral cancer. First, the HPV types (primairly HPV -6 and -11) that cause warts are different from the one (HPV-16) associated with thoat cancer. Second, despite all the news reports about oral/throat cancer related to HPV, it amounts to only about 6,000 cases per year in the entire country -- a very rare cancer!
In 30+ years in a busy STD clinic, I never once saw a patient with oral HPV the he or she caught from his or her own genital infection. It doesn't happen.
Put HPV in perspective. You have experienced a stressful but medically unimportant infection which will never cause you (or a sex partner) serious harm. It isn't worth the anxiety you express. Just follow your provider's advice about treatment of your genital warts, then no worries. Mellow out and let it go.
