Cervical cancer: new screenings in Wales will save lives, says top doctor

As reported by BBC News, changes in cervical cancer screenings will help save lives, not put them at risk, according to a top gynaecologist

Prof Alison Fiander said people should not be worried screenings have dropped from every three to every five years in Wales as tests are “more effective”. Public Health Wales (PHW) said the new rules were for people aged 25 to 49.

More than 1.2m people backed calls for a rethink in a UK petition and politicians in Wales will debate it after 30,000 signed a Senedd petition. Women and people with a cervix – as it could also affect trans men too – who had not tested positive for human papillomavirus (HPV) will now wait two more years between tests.

Health chiefs in Wales said they changed the interval between screenings to the same time as those in Scotland because tests are now more accurate. Cervical screening gaps in England and Northern Ireland remain at three years. But Wales’ public health body did publicly apologise for causing “concern”, and admitted health chiefs “hadn’t done enough to explain the changes”.

Prof Fiander, a clinical lead at the Royal College of Obstetricians and Gynaecologists, said PHW had “missed an opportunity” to help educate people but reassured the public the change was safe and not a cost-cutting exercise. She was involved in the HPV vaccine rollout in Wales, which data shows can cut cervical cancer by 90%, and says having the jab and screening together “can actually beat cervical cancer completely”.

The new process means women and people with a cervix who had not tested positive for HPV will now wait five years instead of three between tests.

“It’s based on the science that over 99% of cervical cancers are caused by HPV,” added Dr Fiander.

“The cervical screening programme is using a new test, testing for HPV and that’s more sensitive than the old method of screening, which was looking for cell changes from the cervix. It allows us to pick up women who are at risk of developing cervical cancer earlier than before.

“For people who have already tested positive for HPV or have been seen in colposcopy, which is where we see women with an abnormal smear, they will be followed up more closely.

“In terms of the experience of being screened, it’s exactly the same for HPV screening.

“A smear is taken from the neck of the womb, the cervix, so the process is exactly the same it’s just that it’s tested in a different manner.”

HPV is a very common virus that most people will come into contact with at some time during their lives but PHW says one or more high-risk type of HPV is present in more than 99.8% of cervical cancers. PHW said the changes are evidence based – and follow a recommendation from the UK National Screening Committee in 2019, bringing the advice for this age group in line with the screening interval for those aged between 50 and 64.

“If you haven’t got HPV, you’re not going to develop cervical cancer,” added Dr Fiander.

“Even if you get a HPV infection the day after screening, it takes between 10 to 15 years for cervical cancer to develop so leaving the screening interval for five years is absolutely fine as long as you go and get screened when you’re invited.

“In the majority of cases, the HPV infection will be cleared by the immune defence system in two to three years without any intervention – and you don’t want to undertake unnecessary treatments. That’s the sort of science that’s underlying the changes.”

HPV testing was successfully introduced in Wales in 2018 and PHW said almost nine out of 10 results show no high-risk HPV.

“It’s true that HPV vaccination is already decreasing the number of women that are developing pre-cancerous changes,” added Prof Fiander.

“So I think combining HPV vaccination with cervical screening means that we could possibly eradicate cervical cancer in the UK, within a few generations which is really exciting.

“But it does mean that everybody that has a cervix needs to be vaccinated and, until then we do need to carry on with screening.”

In the UK, girls are offered the vaccine between the ages of 11 and 13, depending on where they live. The vaccine has also been offered to boys since 2019. Those who are particularly concerned are people who have not received the vaccine, like Maria Dullaghan who had cervical cancer and is still not convinced about the changes.

“The age range they’re looking at changing, the 25 to 49-year-olds, mostly haven’t had the vaccine yet,” said the 37-year-old from Haverfordwest, in Pembrokeshire, who needed a hysterectomy and then started cancer therapy on her 26th birthday.

“Maybe about three-quarters of my friends that age haven’t had it yet – so I don’t think it’s a good idea.

“I had a clear test and then had my diagnosis within five years of that, so I don’t want to see people going through what I did.

“The changes also haven’t been communicated clearly, I think people feel a bit caught out by it coming in quietly at the start of the year.”
