Cervical screening is hugely important in preventing cervical cancer.
According to Public Health England, cervical cancer mortality rates have decreased by up to 70% since the introduction of the NHS cervical screening program in 1988.
However, cervical cancer remains the most common cancer among women under 35, making regular smear tests essential for early detection and prevention.
What Is a Smear Test and How Is It Done?
A smear test is a simple and effective way to detect changes in the cells at the neck of the womb (cervix) that could develop into cancer if left untreated.
The NHS offers cervical screening to all women aged 25 to 64 to check for high-risk HPV (human papillomavirus).
While HPV has many types, certain high-risk strains can cause cervical cell changes that may lead to cancer.
Most cervical cancers are linked to high-risk HPV, which is different from the types that cause genital warts.
During a smear test:
- A healthcare professional inserts a speculum into the vagina to gently open it.
- A soft brush is used to collect a sample of cells from the cervix.
- The sample is tested for high-risk HPV.
If HPV is detected, the laboratory will then check the cells for abnormalities (cytology). The frequency of NHS smear tests depends on age:
- Every three years, from ages 25 to 49.
- Every five years from the ages of 50 to 64.
What Problems Can a Smear Test Detect?
A smear test helps detect high-risk HPV and abnormal cervical cells that could develop into cancer if left untreated. If HPV is found:
- No cell changes detected → You will be invited for a repeat smear test in one year to monitor HPV. If HPV is still present after three years, you will be referred for a colposcopy.
- Abnormal cells detected → You will be referred straight for a colposcopy to examine the cervix more closely.
Why Does the NHS Cervical Screening Programme Test for HPV First?
You may wonder why the NHS tests for high-risk HPV first instead of immediately checking for abnormal cells.
Research has shown that HPV testing is the most sensitive and effective method for identifying women at risk of cervical cell changes.
While some cell changes may occur without HPV, this is far less common, and those changes are less likely to progress to cancer.
By prioritizing HPV testing, the screening program can detect at-risk individuals earlier and more accurately.
Is a Smear Test Painful?
For most women, a smear test is not painful, though some may experience mild discomfort or pressure during the procedure.
If you are feeling nervous, taking slow, deep breaths and relaxing your muscles can help.
If you experience pain, let the healthcare professional know so they can adjust the procedure to make you more comfortable.
What Is Different About Having a Smear Test in a Private Clinic?
There is no difference in how a smear test is performed in a private clinic compared to the NHS. However, private cervical screening offers more flexibility and choice, including:
- Longer appointment times to ensure you feel comfortable.
- The option to have a smear outside of NHS guidelines, such as before age 25 or after 64, or more frequently than the NHS schedule.
- The ability to request HPV and cytology testing at the same time, even if your sample is HPV-negative.
At Kent Family Medical, we always recommend testing for HPV first, but you may choose to have additional cytology testing for peace of mind.
If you have a private smear test, it does not remove you from the NHS screening program.
You will still be invited for routine NHS tests, and we ensure that your results are shared with your NHS GP to keep your medical records complete.
In Summary
Cervical screening plays a crucial role in detecting early signs of cervical cancer.
A smear test is a simple and effective way to check for high-risk HPV and abnormal cells that could develop into cancer if left untreated.
Regular screening, whether through the NHS or a private clinic, ensures early detection and timely intervention, helping to save lives.
If you are due for a smear test, booking your appointment is an important step in protecting your health.
