A precancerous condition of the cervix (the bottom of the uterus) that is more common and more severe in HIV-infected women.
Dysplasia of the cervix epithelium, often premalignant (i.e., precancerous), characterized by various degrees of hyperplasia, abnormal keratinization (forming horny epidermal tissue), and condylomata. Considerable evidence implicates human papilloma virus (HPV) in the development of CIN. Immunosuppression may also play an important role in facilitating infection or persistence of HPV in the genital tract and progression of HPV-induced neoplasia. See Condyloma; Neoplasm.
A disease of the membrane that covers the cervix. It is often considered to be pre-cancerous and should be treated.
A term to describe precancerous changes in cells of the cervix. It is detected through a Pap smear. Early detection and treatment is effective in preventing cancer.
A general term used to describe the growth of abnormal cells on the surface of the cervix. Numbers from 1 to 3 may be used to describe the degree of abnormal changes, with 1 representing the lowest degree (and thus less problematic). CIN-1 is equivalent to mild dysplasia (abnormal cells), and often disappears on its own without treatment. CI N-2 or 3 is equivalent to moderate to severe dysplasia (pre-cancer).
Abnormal, potentially pre-cancerous cell changes of the cervix. The abnormality can be graded as mild (CIN-1), moderate (CIN-2) and severe/CIS (CIN-3)
A general term used to describe the growth of abnormal cells on the surface of the cervix. Numbers from 1 to 3 (as in CIN 1 or CIN 3) are used to describe the degree of abnormal changes that have developed.CIN 1 is equivalent to mild dysplasia (abnormal cells), and often disappears on its own without treatment. CIN 2 or 3 is equivalent to moderate to severe dysplasia (pre-cancerous conditions that require treatment).
(CIN): Another term for dysplasia; a noncancerous condition that occurs when normal cells on the surface of the cervix are replaced by a layer of abnormal cells. CIN is classified 1, 2, or 3.
abnormal growth of cells of the uterine cervix, suggesting an early stage of cervical cancer. Human papillomavirus (HPV) and HIV infection are associated with an increased risk of CIN. There are 3 grades of severity: CIN I, CIN II and CIN III. A newer classification system divides these 3 classes into 2 categories: low-grade and high-grade squamous intraepithelial lesion (SIL). See also cervical dysplasia, squamous intraepithelial lesion.
A condition of the cervix, in which abnormal cells are present on the surface of the cervix. Over time, these cells may become cancerous. CIN is classified as I, II or III, depending on its severity. CIN1 often clears up without treatment, but a repeat smear test is needed to check.
A grading scale used to describe the growth of abnormal cells on the surface of the cervix. Scale from 1(mildly abnormal) to 3 (severely abnormal).
term used to classify the degree of precancerous change in cells of the cervix in a condition called cervical dysplasia.
The development of precancerous cells (cells that, by their appearance, have the potential to turn into cancer) in the cervix.
Neoplasia cervical intraepitelial (CIN) Another term for dysplasia; a noncancerous condition that occurs when normal cells on the surface of the cervix are replaced by a layer of abnormal cells. Otro término para la displasia cervical; es el crecimiento anormal de células en la superficie del cuello uterino. Se considera a la displasia precancerosa, y puede progresar a un cáncer cervical si no se la trata.
(SER-vih-kul in-tra-eh-pih-THEEL-ee-ul NEE-o-play-: CIN. A general term for the growth of abnormal cells on the surface of the cervix. Numbers from 1 to 3 may be used to describe how much of the cervix contains abnormal cells.
Cervical intraepithelial neoplasia, or CIN, is the abnormal growth of precancerous cells in the cervix. Most cases of CIN stay the same or are eliminated by the host's immune system without intervention, but a small percentage of cases progress to become cervical cancer, usually cervical squamous cell carcinoma, or SCC. The major cause of CIN is infection with the sexually transmitted human papillomavirus (HPV), usually the high-risk HPV type 16.
