Colposcopy: Comprehensive Textbook and Atlas

Description:

This comprehensive textbook and atlas provides detailed guidance on the performance and interpretation of colposcopy, with a particular focus on the diagnosis of precancerous cervical, vulvar, and vaginal lesions. The book not only describes the role of colposcopy in state of the art cervical cancer screening and triage but also covers the prevention, diagnosis, and management of cervical cancer in low-resource settings, where the vast majority of cases occur worldwide. The indications for colposcopy are clearly identified, and its use is described in a variety of specific circumstances, including during pregnancy, following surgical interventions and radiation treatment, and in the immunocompromised patient. The book will be of value for gynecologists and gynecologic oncologists, general practitioners, and family practice doctors; furthermore, physician assistants, nurses, and midwives will find it very useful for training and as a source of reference, regardless of whether they are working within an established screening program based on cytopathology and/or HPV testing or within a low-resource environment applying visual inspection as the primary screening strategy.
