transformation zone

The **transformation zone** is a critical area on the cervix where the type of epithelial cells changes from columnar to squamous. This zone is especially important in gynecology because it is the most common site for precancerous changes and cervical cancer to develop. Regular screening through Pap smears and HPV testing focuses on this region to ensure early detection and prevention of cervical abnormalities. Understanding the transformation zone helps in accurate diagnosis and effective treatment of cervical health issues.
