Early Detection Increases Survival
The American Cancer Society's most recent 2012 estimates for cervical cancer in the United States are:
About 12,710 new cases of invasive cervical cancer will be diagnosed.
About 4,220 women will die from cervical cancer.
Some researchers estimate that non-invasive cervical cancer (carcinoma in situ) is about 4 times more common than invasive cervical cancer.
Most cervical cancers begin in the cells lining the cervix. These cells do not suddenly change into cancer. Instead, the normal cells of the cervix first gradually develop pre-cancerous changes that turn into cancer. Doctors use several terms to describe these pre-cancerous changes, including:
- cervical intraepithelial neoplasia (CIN)
- squamous intraepithelial lesion (SIL)
These changes can be detected by the Pap test and treated to prevent the development of cancer.
