cervical intraepithelial neoplasia
Precancerous condition of the cervix categorized into grades (CIN 1, 2, 3) based on severity of cellular abnormalities.
Full Definition
Cervical intraepithelial neoplasia represents abnormal growth of cells on the surface of the cervix that may progress to cervical cancer if left untreated. The condition is graded from CIN 1 (mild dysplasia) to CIN 3 (severe dysplasia/carcinoma in situ), with higher grades indicating greater likelihood of progression to invasive cancer. CIN is typically detected through cervical cytology screening and confirmed by colposcopy and biopsy. Treatment options vary by grade and may include observation, cryotherapy, or surgical procedures.
Usage
Usage note: Always specify the grade (CIN 1, 2, or 3) when mentioned in clinical contexts.
