What is it?
This is a test to detect abnormal cells in the cervix (the cervix is the opening to the womb from the vagina). The NHS currently invites all 25-64 year old women to have this done routinely. The test is relatively short and involves you lying down whilst a medical instrument called a speculum is gently inserted into your vagina. This holds the walls of your vagina open so that your cervix is visible. A small soft brush is then used to take some cells from the surface of your cervix. The sample of cervical cells will then be sent to a laboratory and examined under a microscope. The cells are examined for early changes that, if ignored, could develop into cancer of the cervix. You are unlikely to develop cervical cancer if you have regular cervical screening tests at the times advised by your doctor.
