D00-D09: In situ neoplasms

D06: Carcinoma in situ of cervix uteri

Carcinoma in situ of the cervix uteri, also known as cervical intraepithelial neoplasia, is a precancerous condition. It implies that abnormal cells have been detected on the surface of the cervix, but those cells haven't spread deeper or to other parts of the body. This condition is primarily caused by persistent infections with certain high-risk subtypes of human papillomavirus (HPV), a sexually transmitted infection. The disease doesn't typically cause symptoms, but in some cases, may result in unusual vaginal bleeding or discharge. Over time, if not treated, these abnormal cells might develop into cervical cancer. However, with regular gynecological screenings, this condition is usually detected early, before it can progress into something more serious. Therefore, it's crucial to follow recommended schedules for regular screenings. The exact progression of the disease may vary from individual to individual, depending on various factors, including overall health, age, and the nature of the HPV subtype involved.
