Women who identify as men are not being routinely offered potentially life saving NHS screening for breast and cervical cancer, amid fears it might offend them it is claimed.

However men living as women are being invited for cervical smear tests even though they do not have a cervix, an official guidebook states.

The invitations were yesterday accused of being “ludicrous”.

David Davies MP, who has campaigned against Government plans to let people legally 'self-identify' their own gender, told the Mail on Sunday: “This NHS effort to be politically correct is putting the lives of women who claim to be men at risk.”

He claimed it was also “wasting the time of men who claim to be women by offering them tests for organs they do not have”.

Laura Perrins, A conservative women’s campaigner, told the paper: “We've now got to the point where state collusion with this transgender agenda is endangering the health of women. It's a ludicrous use of NHS resources to invite men for a cervical smear test, while it's immoral and dangerous not to invite women.”

A 24-page Public Health England booklet giving information on NHS screening programmes for trans people explains who is routinely invited for tests.
