Good Day! I was recently diagnosed at 21yrs (4months after losing my virginity) with CIN2 after abnormal pap smear and subsequent colposcopy. I have only had sex with 1 person.  I engage in vaginal and oral sex. I want to know what are the chances of having cell changes in the neck region as well? And what is the risk of gettting head and neck cancers from hpv? Also is it safe to still engage in oral sex with my boyfriend at this point (protection or no protection)? Thank you in advance.

Hi, You said that you have been diagnosed with CIN2. It is an abnormality of cells in cervix that can lead to cervical cancer if left untreated. CIN2 means between 1/3rd and 2/3rd cells in cervix are transformed onto abnormal cells. It is caused by Human papillomavirus (HPV). HPV doesn't lead to any changes in your neck. Certain types of HPV causes cervical cancer and certain types of HPV causes genital warts. HPV does cause pharyngeal cancer. But it generally occurs in males above 40 years of age. So, It's quite uncommon in a young woman like you. No need to worry about it. As you already have developed HPV infection, you need not be worried about getting new HPV infection from your boyfriend. But always make sure to use protection like condoms. They protect you from all kind of sexually transmitted infections like chlamydia, HIV, syphilis, etc. And coming to the treatment part, your gynecologist will perform some procedure like laser therapy, freezing therapy (cryotherapy) to remove the abnormal cells. She might also use LL ETZ (a procedure using a loop of wire) to remove or scrape out the abnormal cells. Also make sure to undergo repeat testing of pap smear and colonoscopy after 6 months of having treatment for your CIN2.
