Cervical cancer is the second most common cancer among women worldwide. This book serves as a concise teaching manual on visual inspection with acetic acid (VIA) and with Lugol's iodine to train health personnel, especially in developing countries, with the aim to detect this disease in the early pre-invasive phase and save women's lives. These two simple low-technology screening tests based on the ability of the trained health-care personnel to detect acetowhite areas, or yellow non-iodine uptake areas, in the cervical transformation zone are being evaluated as potential alternatives to cervical cytology.
