Is CIN3 a precancer?
Cervical intraepithelial neoplasia (CIN) is a precancerous condition in which abnormal cells grow on the surface of the cervix.
How long does CIN 3 take to develop?
Whereas CIN2/3 typically develops within a few years of infection with HPV (4–6), progression to invasive carcinoma is generally thought to require much more time.
Will a hysterectomy cure CIN3?
These data suggest that: adequate colposcopy is an accurate method to rule out invasive cervical cancer and abdominal or vaginal hysterectomy is an effective therapeutic procedure in women with CIN III who have completed reproductive function.
Is cin3 serious?
CIN 3 is not cancer, but may become cancer and spread to nearby normal tissue if not treated. Treatment for CIN 3 may include cryotherapy, laser therapy, loop electrosurgical procedure (LEEP), or cone biopsy to remove or destroy the abnormal tissue. CIN 3 is sometimes called high-grade or severe dysplasia.
What are the risks of CIN 3 + and cervical cancer?
Five-year risks of CIN 3+ and cervical cancer among women with HPV-positive and HPV-negative high-grade Pap results The risks of CIN 3+ among women with HPV-negative high-grade Pap results were lower than those among women with HPV-positive high-grade Pap results, especially after AGC.
When to have a Pap test for cervical neoplasia?
If the Pap tests remain normal, the current recommendations are for a repeat Pap every 3 years from ages 21 to 29, and a Pap and HPV test every five years for women 30 to 65. Pap tests cannot prevent cervical intraepithelial neoplasia, but they are beneficial because they can detect it in its earliest stages.
How is cervical intraepithelial neoplasia ( CIN ) 1 classified?
Cervical intraepithelial neoplasia may be classified according to how much epithelial tissue is affected: Low-grade neoplasia (CIN 1) refers to dysplasia that involves about one-third of the thickness of the epithelium.
How are cervical cancer screening programs have changed?
Cervical cancer incidence and mortality have decreased due primarily to screening programs using the pap smear. As more outcome data has become available, screening, and treatment guidelines for cervical intraepithelial neoplasia (CIN) have evolved.
