Cervical tumor
Cervical intraepithelial neoplasia(CiN)
Cervical intraepithelial neoplasia(CIN)
Introduction A group of precancerous lesion closely associated with the cervical cancer, which reflect the continuous process of the development of the cervical cancer 1.cin caused by virus infection rarely develop cervical cancer 2. ciN caused by multifactors may develop cervical cancer 3.TBS diagnosing system by ncl 1).atypical squamous cells, ABC (2).low-grade squamous intraepithelial lesion, LSIL 3.high-grade squamous intraepithelial lesion, HSIL LSIL means CiN L, rarely develop cervical cancer HSIL menas CiN II and ll, may develop cervical cancer
