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 papilloma virus (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 oropharyngeal cancer. But it generally occurs in males above 40 years of age. So, its 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 LLETZ (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 colposcopy after 6 months of having treatment for your CIN2.
