Pap test. The Papanicolaou test (abbreviated as Pap test, known earlier as Pap smear, cervical smear, or smear test) is a method of cervical screening used to detect potentially pre-cancerous and cancerous processes in the cervix (opening of the uterus or womb).
The Pap test is a simple test used to check for abnormal changes to the cells of the cervix that may lead to cervical cancer. Pap tests are the best way for women to lower their risk of getting cervical cancer. The Pap test is a screening test â it is not a test for diagnosing cancer. Screening for cervical cancer is possible because the cervical cells go through a series of changes before they become cancerous. If changes are found, more frequent Pap tests are done to see if the cells return to normal.
