Labour MP Alison McGovern said the death of Sophie Jones, who died of cervical cancer aged 19 after she was refused a smear test because of her age, shows that a "culture change" is needed within the NHS.
Speaking during a debate on lowering the age of eligibility for cervical screening from 25, she said that the NHS "must listen to young women".
"There are lots of forces in society that are set up to undermine young women," she added. "Please let's not have the NHS be one of them."
A mother has prompted a debate in Parliament after losing her 19-year-old daughter Sophie Jones to cervical cancer in March, saying that her child couldn't have a test due to her age.
In the commons, Steve Rotherham MP stated that he wasn't calling for routine cervical screening for all women under 25, but for "guidance, that women should be able to request a smear regardless of their age".
ITV News' Medical Editor Lawrence McGinty reports:
Jo's Cervical Cancer Trust, a charity dedicated to those affected by cervical cancer and cervical abnormalities, told ITV News that women who are invited to take smear tests are increasingly failing to make the appointments.
Following 19-year-old Sophie Jones' death from cervical cancer, 322,000 people have supported a campaign to change the law on smear tests
MPs will today discuss lowering the age limit for cervical screening from 25 to 16 after the record-breaking petition drew 200,000 more signatures than is required to trigger a Parliamentary debate.
The campaign was started by the family of the Merseyside teenager, who died in March after doctors refused her request for a smear test.
She had been suffering from pelvic pains, prolonged menstruation and loss of appetite, but was not screened because of her age.
The twin sister of a 19-year-old who died from cervical cancer despite repeated pleas to doctors for a smear test has said she believes her sibling would still be alive if she had been screened.
Ashleigh Jones told Good Morning Britain her sister Sophie would still be alive if doctors had given her a smear test after she complained of pelvic pains, prolonged menstruation and loss of appetite.
She said: "I think it would have saved her life. I think even if she had had it two months earlier, it could have saved her life."
Sophie's Mum Peri Cawley, Ashleigh and other sister Chelsea were speaking ahead of a debate in Parliament lower the age women are eligible for smear tests from 25, in the wake of Sophie's death.
The age at which young women can first be tested for cervical cancer will be up for debate in Parliament later today, MPs have said.
A campaign to lower the age was brought by a bereaved mother, who lost her 19-year-old daughter in March when doctors failed to correctly diagnose the cervical cancer she was suffering from.
Sophie Jones had complained of pains in the pelvic area, severe back pain and lower stomach pain back in January 2013, but was not diagnosed until November after numerous doctors had dismissed her pleas for a smear test, partly because she was under 25.
During the summer of 2013 Sophie stopped eating and was referred to a gastroenterologist as doctors suspected she had Crohn's disease.
She was then referred to a gynaecologist who admitted her that day and immediately referred her for a colposcopy which showed she had cancer.
The campaign to bring this debate to Parliament secured more support than any other in the government e-petition website's history - beating Stop the Badger Cull' and 'Convicted London Rioters should lose all benefits!'.
A 35-year-old woman who was two years overdue for a smear test has told Daybreak of the difficulties she faced when she was diagnosed with cervical cancer,
Samantha Kemp, who was 32 at the time of diagnosis, said doctors discovered "quite severe abnormal cells" and sent her in for an MRI, which revealed a tumour small enough "that it meant I did not have to have a hysterectomy".
"That for me that was my scariest point, was having that situation of not knowing if I could have children anymore."
It is misleading to suggest the rise in overdue smear tests is the result of a lack of GP access, the Government has said.
A Department of Health spokeswoman claimed there had been a sharp rise in the number of women screened for cervical cancer in the wake of Jade Goody's death in 2009, and now, fewer were choosing to get screened:
The 11% rise in the number of women who have failed to have a smear test is "extremely worrying", Labour have said.
Shadow health minister Liz Kendall said:
