The first test to be widely used to screen for any type of cancer was the Pap test, which is used to screen for cervical cancer and was developed about 100 years ago. Despite this test being readily available and easy to perform, cancer of the cervix is still the fourth most common cancer in women. The earlier cervical cancer is identified, the easier it is to treat.
The Pap test identifies precancerous lesions on the cervix, which is important, because the precancer stage has no symptoms. Once cells/lesions have developed into cancer, symptoms may include:
Abnormal, sometimes bloody discharge
Bleeding between periods
Bleeding after intercourse
