Why smear tests still save lives

Cervical Cancer Prevention Week, which this year is happening week commencing 19th January, is an important reminder of how powerful prevention really can be. Cervical cancer is one of the most preventable cancers, yet screening rates have fallen in recent years, often because life gets busy, or appointments feel easy to postpone. Smear tests may not be something anyone looks forward to, but they remain one of the most effective tools we have for protecting women’s health.

At EssexPrivateGP, we regularly speak with women who feel unsure about screening, or who are overdue because it slipped down the priority list. That’s why we feel this awareness campaign is a good opportunity to revisit why cervical screening still matters.

Why cervical screening is still important

Cervical screening, often called a smear test, is designed to detect high-risk types of human papillomavirus (HPV). HPV is very common and usually harmless, but certain strains can cause changes in cervical cells that may progress into cervical cancer. Screening doesn’t look for cancer itself, but for early changes that can be managed long before cancer develops.

This is why smear tests are so effective. They allow problems to be identified early, often before any symptoms appear. Cervical cancer can take years to develop, and in its early stages it may not cause noticeable signs. By the time symptoms such as abnormal bleeding or pelvic pain occur, the condition may already be more advanced.

Regular screening gives reassurance when results are normal and provides an early warning system when they’re not. Even though cervical cancer is now less common than it once was, this is largely because screening works, not because the risk has disappeared.

Understanding the move to five-yearly screening

You may have heard that cervical screening intervals in England have changed. As of 2025, NHS cervical screening is now offered every five years for most women aged 25 to 64, rather than every three. This change follows improvements in the screening test, which is now more sensitive at detecting high-risk HPV earlier and more reliably.

According to Cancer Research UK, this update is based on strong evidence that HPV testing offers excellent protection, making five-year screenings safe and effective for women who test negative. Importantly, this doesn’t mean screening is less important, it just means the science behind it has advanced.

That said, it’s still vital to attend when you’re invited and to speak to a GP if you have symptoms in between screenings. Changes such as bleeding after sex, unusual discharge, or persistent pelvic pain should always be checked, regardless of when your last smear was.

Some women also choose private screening for flexibility, reassurance, or because they want more time to talk through their results. At EssexPrivateGP, we provide cervical screening appointments in a calm, unhurried setting, with clear explanations at every stage.

In addition to the HPV cervical test, EssexPrivateGP offers cervical cytology screening, which is useful in identifying other abnormalities such as ovarian and endometrial cancers (not part of routine NHS cervical screening unless there’s an HPV positive result).

Ongoing prevention

HPV vaccination has been a major breakthrough in reducing cervical cancer risk. The vaccine protects against the most common high-risk HPV strains and is routinely offered to young people in the UK. For more information including vaccine doses for different groups visit GOV.UK HPV vaccination guidance.

However, the vaccine doesn’t protect against all HPV types, which means regular smear tests are still essential. Prevention works best when vaccination and screening go hand in hand. Together, they dramatically reduce the risk of cervical cancer developing at all. For women who missed vaccination earlier in life, screening remains the most important protective step.

At EssexPrivateGP, we understand that cervical screening is personal. Our approach is gentle, respectful, and centred around your comfort, with time to ask questions and discuss results without feeling rushed. Get in touch today to book your appointment.
