YOUR feature on cervical cancer ("Advice from medical experts about cervical cancer", The Herald, January 23) is factually incorrect.

It is based on screening intervals and age range for England. The age range you quote is every three years for women aged 25-49 and every five years for women aged 50-65. This is not the situation in Scotland, where women are invited every three years from age 20 until age 60.

This is under review and is likely to change in 2016 but the figures quoted in the article do not reflect practice in the Scottish screening programme.
