This is a recurring topic on UKY, and one which there seems to be some misinformation/misunderstandings about.
Pap smears are called "smear tests" in the UK. When you arrive and register with your local GP, your name will automatically be entered in to the NHS Cervical Screening Programme.
This programme, implemented in 1988, is a national computerised system designed to invite women to be screened, and to follow up their results. Woman are first invited at 25 and remain in the system till age 65.
The intervals are:
Age group (years) Frequency of screening
25 First invitation
25 - 49 3 yearly
50 - 64 5 yearly
65+ Only screen those who have not been screened since age 50 or have had recent abnormal tests
The interval times offered in the UK seem to upset some expats. People used to having a pap smear every year, or those with a history of abnormal smears sometimes feel that having a smear every 3 years is not enough.
If you have had an abnormal smear in the past,
please let your GP know. There is also nothing from stopping you from requesting a smear test more often than the 3 year recall if it makes you more comfortable.
You can get your smear test done at several locations.
1. GP's office
2. Regional family planning clinics. These will have a mix of appointment based and walk in clinics. Ask your GP for a local list.
3. GUM Clinic. (Genitourinary Medicine) Ask your GP for the local GUM clinic information. These clinics also do confidential STD and pregnancy testing. Walk in and appointment based.
Remember that the 3 year recall is only for patients that have had a normal history. It gets a bit more complicated if abnormal calls are located.
There are several grades of abnormalities.
1. Borderline changes (aka as ASCUS in the US): This is considered to be a low grade change and in most cases, the patient will be invited back for another smear test in 6 months. If the second smear is negative, the patient will be invited back every 6 months, until 3 consecutive negatives are reached. If that happens, the patient is returned to normal recall. In the event that pre-malignant changes (dyskaryosis) are found on a subsequent smear, the patient may be monitored, or referred to colposcopy, at the GPs discretion.
2. Low Grade (Mild) Dyskaryosis: Patients may be monitored since some low grade lesions do regress on their own, or referred to colposcopy.
3. High Grade (Moderate to Severe) Dyskaryosis: Patients referred to colposcopy for treatment.
4. Malignancy: Very rare since cervical cancer is a slow growing entity. Most patients will have not had a smear test in over 10 years, or perhaps never. In my 15 years in the field, I have seen only a handful of flat out cervical cancer cases.
If dyskaryosis is found on a smear, the patient will then have a yearly recall for 10 years following the first normal smear post treatment. This clock resets itself each time a new abnormality is noted, so no one will be returned to 3 yearly recall without having had 10 years of negative smears.
I hope that this is a helpful post. The UK system is what it is, and I am not posting any of this to start a debate on which system is *better*. What I can say to you as a professional who has worked in both countries reading the smear tests, is that it was designed to maximise the number of women tested, with the most efficient timeframe, and I am completely comfortable with having my smear test done every 3 years.
