Hello. Thank you for writing to us at healthcaremagic Genital Hpv causing cancerous changes of cervix suggests that she likely carries a high risk Hpv type i.e one or more of type 16, 18, 31, 33. Only a small percentage of patients infected with high risk Hpv types go on to develop cencerous cell changes. In the majority, body s own immunity takes care of the infection and gets rid of it. In those few in whom infection with these high risk Hpv types persists, some of them may go on to develop cancerous cell changes. Persistence of Hpv infection is the basic underlying factor. Considering the scenario that she had cancerous cell changes, it is very likely that she still carries the Infection with high risk Hpv and has also likely passed on the infection to you and probably that also caused genital warts in you. Physical examination is usually sufficient in case of warts. Biopsy can be confirmatory in doubtful cases. Since you also likely carry the virus, therefore, you can infect anyone you come in sexual contact with. However, as I told you before, in most of those who have genital Hpv, body s own immunity takes care of the infection and ultimately gets rid of it,therefore it is very likely that you could be free of the infection an year later, provided you are not exposed to new infection from subsequent sexual encounters.
