There's a warning lives could be put at risk because of changes to the age women in Wales will be called for a smear test. Currently all women between 20 and 64 are invited for a screening but from Sunday the starting age will rise to 25.
The Welsh Government say the decisions are based on expert advice, but not everyone's convinced as our health reporter Rob Osborne has been finding out.
Ian Lewis from Tenovus told ITV News that a lot of research has been done into the benefits of screening women under 25 versus the harm it would cause through "unnecessary worry."
He said a bigger concern was the low uptake in women going for smear tests when invited - only one in four women attend appointments when called.
Alison Denton is calling on the Welsh Government to rethink changes to the cervical screening programme that come in on Sunday. Her daughter had precancerous cells detected during a smear test.
She told ITV News the Welsh Government needs to provide more information on the science it says supports the changes.
Concerns are being raised over changes to the cervical screening programme in Wales which come into effect this weekend.
From Sunday, the starting age for woman to have smear tests will rise from 20 to 25 and women over 50, who are currently tested every three years, will only be called for a test every five years.
Lindsay Whittle, Plaid AM for South Wales East, says he has raised the issued with Health Minister Mark Drakeford AM, after he was contacted by two women affected by cervical cancer.
He said: "I have grave concerns that this decision will lead to more cases of cervical cancer laying undetected for longer. I have two constituents who are examples of the importance of early detection which with cancer we are always told is crucial.
"Wales has been first on issues like free concessionary bus passes, charges on carrier bags and free prescriptions. But i don't like the idea of being first on an issue which could affect women's health and a huge chunk of the Welsh population."
