The NHS in England is introducing a ‘superior’ test for cervical cancer, following a successful pilot scheme.
Experts say it is a switch that could pick up an extra 600 cancers a year.
Women invited for a routine smear test will now automatically be checked for an infection called HPV (Human Papilloma Virus), which has been strongly linked to cervical cancer.
Until now, an HPV test has only been done if doctors noticed abnormal cells in the smear sample.
