All women who have ever been sexually active should have regular cervical smear tests every three years between the ages of 25 and 69. This includes women who have been immunised against HPV. This test detects abnormal cells which, if left untreated, could become cervical cancer. Very often these cells are made abnormal by a human papillomavirus (HPV) which is a sexually transmitted virus. Regular tests and treatment reduces the likelihood of this sort of cancer by around 90%.
