Cervical dysplasia causes

Overview
Cervical dysplasia appears to arise from a chronic infection of the cervix by Human Papilloma Virus (HPV). This is the same virus that causes the common wart. There are approximately 100 strains of HPV. Thirteen of these strains appear to cause cervical dysplasia and lead to the development of cervical cancer. Hormonal treatments such as birth control pills have also been linked to higher rates of cervical dysplasia.
