The publication in 2009 of the new recom- mandations by the American College of Obstetricians and Gynaecologists (ACOG) about the screening of cervical cancer enabled us to optimize the treatment, especially in young patients. The aim of these modifications is to decrease overtreatment of low grade lesions and thereby the risk of obstetrical complica- tions. The objective of our article is to briefly recall these new guidelines together with a study conducted in our Department of Obstetrics and Gynaecology which aim is to confirm that our practice follows these instructions and to check that these procedures are safe for the future of these young patients.
