The family of a young woman who died from cervical cancer after being diagnosed too late are backing a national campaign to stop the same tragedy happening to other people's daughters.

Despite having a smear test and being told by three Bradford doctors that she had nothing more serious than a sexual infection, 28-year-old Kelly Glossop from Bierley died of cancer last August aged 28 - her weight plummeting from 13 stone to just four.

Her angry family claim she was "never given a chance" by medical professionals who they claim "missed" the disease.

The family claim Kelly was wrongly given the all-clear by Leeds Teaching Hospitals NHS Trust who analysed her last smear test in 2000.

They are also unhappy that despite complaining to her own GPs of stomach pains and bleeding for two years she was not diagnosed until 2003.

Kelly's stepfather Gerald Robertshaw, 50, said they made repeated visits to three GPs at Highfield Health Centre in Proctor Street, off Tong Street, in the two years after the smear. She was finally diagnosed with cancer a year later in the Isle of Man where she had been working for B&Q as an office administrator.

Mr Robertshaw said: "She was all alone in the Isle of Man when they finally broke the news to her. It should have been picked up on while she was still here in Bradford at home with us.

"The abnormal cells should have been picked up at the smear test and she should have been referred for further investigations by her doctors but instead they just missed it and went down the road of sexually transmitted disease."

They have already been told by the General Medical Council that the doctors from the surgery have no case to answer.

Mr Robertshaw and Kelly's mother Irene and dad Steven Glossop say they are thinking of taking action against Leeds Teaching Hospitals NHS Trust which carried out the smear test analysis.

A spokesman for the Trust said due to pending legal action he was unable to discuss Kelly's case.

The Medical Protection Society issued a statement on behalf of Highfield Health Centre saying: "The centre appreciates the sad circumstances surrounding this case and wishes again to offer their condolences to Kelly Glossop's family.

"The doctors who cared for Kelly have an ongoing duty of confidentiality to their patients and therefore are unable to comment publicly on the specific details of this tragic case."

The family is consulting London solicitor Sarah Harman - sister of former Government Minister Harriet Harman - who was recommended to them by Jo's Trust a charity which fights cervical cancer.

The family are now putting its strength behind Jo's Trust, a national charity calling for better screening of women for cervical cancer and wants to raise public awareness of the condition.

The family want to see cervical smears offered to young women as soon as they become sexually active and smear tests offered every 12 months instead of the current three years.

Last year the Government upped the testing age from 20 to 25 years of age because the under 25s had a low mortality rate from the disease.

But Mr Robertshaw said: "We can't bring Kelly back but we can help save other people's daughters. We are backing Jo's Trust. We are calling for better, earlier and more frequent screening. We want girls having sex at such a young age to know there are other risks than getting a sexual infection or getting pregnant."
