What is the most common type of cervical cancer?
Most cervical cancers are either squamous cell, adenocarcinoma or less often, adenosquamous. They often develop from precancerous changes in the cervix. Most of these changes are caused by a long-term infection with the human papillomavirus (HPV). Most precancerous changes in the cervix do not progress to cancer. When they do, it often takes several years for cancer to develop.
