DIY Screening for Cervical Cancer
Reported November 4, 2011
(Ivanhoe Newswire) -- A new Do-It-Yourself screen for cervical cancer could
help prevent the disease in thousands of women who, for a number of reasons,
cannot have a smear test.
The test, which detects the virus responsible for cervical cancer, was
widely accepted by women in the trial and was more effective than the
traditional smear test at picking up earliest signs of the disease.
The study was led by Professor Attila Lorincz, Queen Mary, University of
London and was tested on over 20,000 women in Mexico. Half of the women took
the DYI test at home while the other half visited a clinic for the smear
test. The DIY test picked up more than four times as many cases of cervical
cancer and more than three times as many cases of a pre-cancerous condition,
which can be treated to prevent the disease from developing.
Most importantly, uptake for the at-home test was higher than for the smear
test suggesting that women prefer this type of screening. However, according
to the researchers the test still has its limitations such as its tendency
to pick up more women who, after further tests, turn out to be healthy and
this increases the burden on the health care service. Further research is
needed to address these issues.
Cervical cancer kills 273,000 women worldwide every year and it is more
prevalent in poorer countries where women have no access to screening.
The DIY test has the potential to help thousands of women around the world
who live in countries where smear testing is not accessible. It could also
benefit women in richer nations who are unwilling or unable to visit a
clinic.
Around 2,500 women in the UK are diagnosed with the disease each year and it
is far more common in women who, for one reason or another, have never had a
smear test. These women are often from poorer backgrounds with poorer
health, which also puts them at a greater risk of getting cervical cancer.
The existing smear test is given by a nurse or doctor in a clinic and must
be checked manually by a cytologist who makes a subjective judgment by
examining the sample under a microscope. The new test can be taken by a
woman in her home and the sample can be assessed by an automated system.
Professor Lorincz, who also helped to develop the test was quoted as saying,
"Cervical cancer has a devastating global impact because it affects
thousands of women of all ages. Unlike many forms of disease, we can
actually prevent cervical cancer but only if women have access to screening
or if young girls are vaccinated against the virus that causes cervical
cancer."
"This research is tremendously exciting because it gives us a new and easier
way for women to take part in screening," Lorincz was quoted as saying.
"Our findings show that women are happy to take the test and that it is very
sensitive at picking up the women who are at risk of developing cancer. This
sensitivity is vital for a woman who may only get tested once or twice in
her life," Lorincz was quoted as saying.
