Health experts have called for NHS screening for cervical cancer to be rolled out to women over 64 after research found one in five new cases is diagnosed in this age group. Around 3,000 cases of cervical cancer are diagnosed in the UK each year and it is the most common cancer in women under the age of 35. But researchers at Keele University said that on average, 20% of the 3,121 new cases diagnosed each year were in women aged 65 and over – the age at which the screening programme, commonly known as smear testing, currently ends.
