Very few cancers can be identified so far ahead of the danger point as cancer
of the cervix. The cells lining the surface of the cervix begin to show changes
visible under a microscope a decade or more before invasive cancer develops, in
plenty of time for definitive treatment. For this reason, a regular, properly
performed and interpreted Pap smear is one of medicine's most effective
preventive methods.
The stages of progression from a healthy cervix to cancer begin with what is called mild dysplasia: precancerous alterations in structure and activity. Subsequently, altered cells spread from the surface of the cervix down toward the underlying tissue. In the early stages, cancerous changes may disappear on their own, but once these cells fully penetrate the lining, progression to true cancer usually occurs within 5 to 10 years.
Medical treatment consists of watchful waiting for spontaneous regression during the early stages and more aggressive removal of the cervical lining by laser, freezing, or other techniques if no regression occurs. These options are usually successful; however, they are invasive and frequently uncomfortable.
