Reducing the screening age might save one life per 1,000 ladies checked, the scientists say.
However specialists warning there are various different issues, together with value.
Most cancers Analysis UK says it’s nonetheless “not clear if lowering the breast screening age would give any further profit in comparison with the UK’s current screening programme”.
The charity says the precedence ought to be getting most cancers providers “again on monitor” for girls aged 50-70, after disruption attributable to the pandemic.
Throughout lockdown, most cancers screening programmes which detect early indicators of bowel, breast and cervical most cancers have been paused in Wales, Scotland and Northern Eire, though not formally stopped in England.

“Within the fullness of time, it’s price serious about decreasing the age of screening.”
Nevertheless, he mentioned the monetary value of this ought to be taken into consideration, and extra analysis was wanted into the affect of contemporary screening gear on diagnoses.
Sophia Lowes, well being data supervisor at Most cancers Analysis UK, mentioned the charity had issues concerning the examine outcomes.
“Many ladies acquired false optimistic outcomes and a few ladies would have been over-diagnosed with cancers that will by no means have gone on to trigger them hurt,” she mentioned.
“Whereas analysis into bettering our screening programmes stays important, screening programmes are already below big pressure as a result of pandemic, and the precedence proper now ought to be getting providers again on monitor for girls aged 50-70.”
The charity calculates that six occasions extra ladies of their 40s, in comparison with these aged 50-70, would have to be screened to save lots of one life.
