Cervical cancer, or cancer of the cervix, is cancer of the entrance to the uterus (womb). The cervix is the narrow part of the lower uterus, often referred to as the neck of the womb. Cervical cancer occurs most commonly in women over the age of 30. The American Cancer Society estimates that 11,270 diagnoses of cervical cancer will be made by the end of 2009 in the USA. Over 4,000 women in the USA die from cervical cancer each year.
