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).
A Pap test (or Pap smear) checks the cervix for abnormal cell changes. The cervix is the lower part of the uterus (womb), which opens into the vagina. Cell changes can develop on the cervix that, if not detected, can lead to cervical cancer. Cervical cancer can almost always be prevented, and having regular Pap tests is the key.
