What is cancer of the cervix?

Cervical cancer is cancer that starts in the cervix. Since the Pap test became a routine test for women in the United States, cervical cancer is no longer a major health problem here. In fact, it now makes up less than 2% of all cancers in women in the United States. However, in many developing countries where the Pap test is not a routine test, this form of cancer is very common.
