Women aged between 25 and 50 are advised to have a cervical smear carried out every three years. This is a simple, quick test which may detect early changes at the neck of the womb. If treated straight away we can prevent the cancer ever developing. Patients are called for a smear by letter. If you think you are due for a smear but have not been recalled, please let us know. Smear clinics are held during most afternoon surgeries by the practice nurse. After 50 years of age, smear tests are carried out every five years.
