A cervical screening test (previously known as a smear test) is a method of detecting abnormal cells on the cervix. The cervix is the entrance to the womb from the vagina.
Detecting and removing abnormal cervical cells can prevent cervical cancer.
Cervical screening is not a test for cancer; it is a test to check the health of the cells of the cervix. Most women's test results show that everything is normal, but for around 1 in 20 women the test will show some abnormal changes in the cells of the cervix.
