An abnormal smear test occurs in about 1 in 12 cervical screening tests, but in nearly all cases do not mean cancer.
The medical term for describing abnormal cell changes is Dyskaryosis. Dyskaryosis is not cancer and about 9 out of 10 cases revert back to normal on their own without treatment. Nearly all abnormal tests show no more than small changes in the cervical cells. It means that your smear test has done its job.
Depending on the degree of abnormality, it may be necessary to have a repeat cervical screening test or be referred to a Consultant Gynaecologist for a colposcopy. The urgency of referral depends on the result of the cervical screening test:
An abnormal smear test is often caused by the Human Papilloma Virus (HPV or Wart virus). This is a very common infection and 60-70% women get it at some stage in life. Most women will shake it off through their immunity, but in some women it may linger on and cause an abnormal smear test.
Remember that it is rare for cervical cancer to be found on cervical screening. Cervical screening is designed to find early changes that could become cancer if left untreated.
A colposcopy is a procedure where the lining of the cervix is closely examined using a magnifying instrument called a colposcope to check the cells for abnormalities.
Modern colposcopy clinics are fitted with video equipment that allows the Consultant Gynaecologist to view the examination on a monitor. The patient is able to watch the procedure if they wish, to help reduce any nervousness and anxiety.
After closer examination of the cervical cells, your Consultant will be able to determine the extent of any cell abnormalities and any treatment that is required. If the colposcopy confirms that there are cervical cell abnormalities, a biopsy may be carried out, removing a small sample of tissue for closer examination and testing. The treatment of abnormal cervical cells is almost always 100% successful. Following treatment, it is unlikely that any cell changes will occur in the future.
