HPV can cause genital or anal warts, benign lesions (abnormal Pap test), and also precancerous and cancerous lesions.
HPV has been identified as being responsible for close to 100% of cases of cervical cancer, the second most common type of cancer among women between the ages of 20 and 44. Today, experts are in a position to state that “the association between HPV and cervical cancer is stronger than between tobacco and lung cancer.” [http://www.hpvinfo.ca/hpvinfo/professionals/overview-3.aspx]
HPV is also associated with many other types of cancer, including cancers of the anus, vulva, vagina, penis and throat.
It is also important to consider the psychological effects associated with HPV infection and its possible complications. For example, an HPV infection may be a significant source of stress and anxiety for the individual or be the cause of conflict for a couple.
