Cervical screening (a smear test) checks the health of your cervix. The cervix is the opening to your womb from your vagina. It’s not a test for cancer, it’s a test to help prevent cancer. All women and people with a cervix aged 25 to 64 should be invited by letter. During the screening appointment, a small sample of cells will be taken from your cervix. You’ll get your results by letter, usually in about 2 weeks. It will explain what happens next.
