every year half a
million women are diagnosed with cervical cancer and over half of these women
will die medical aid films has produced this film to explain how many of these
lives could be saved through screaming early detection prevention and treatment
let's hear from an expert in cervical cancer screening to explain how this
works in practice it is important to be
aware that nearly all
cervical cancer is caused by a genital infection with the HPV or human
papilloma virus and this is sexually transmitted HPV infections can be
prevented by giving a course of HPV vaccinations two young girls exposure to
high risk HPV can increase with the number of sexual partners a woman may have so it's
important to vaccinate girls before they become sexually active.

HPV infections are
extremely common in women under the age of 35 but only a small number of women
go on to develop abnormal or precancerous changes in the cells of the cervix
these changes can be found through screening screening is not a test for cancer
it is a method for detecting precancerous changes in women which if left
untreated may lead to cancer in most countries screening is recommended for
women between the ages of 30 and 49.
In some countries
such as uganda screening starts at the age of 25 the world health organization
recommends that women are screened once every five years there in some
countries they
recommend every three
years. HIV positive patients should be screened, once a year as HIV women have
a higher risk of contracting HPV infection and a higher risk of developing
cervical cancer is our health worker who will describe some different screening
tests now we're going to look at the four main tests visual inspection with
acetic acid VI a visual inspection with Lugo's ID ein test really happened
nicolau Pap test and the HPV DNA test which chest you use depends on the
equipment you have available in your community.
The first two tests
involve looking at the service so the results are available right away the last
two tests require laboratory analysis so you have to wait for the results this
test is also known as the vinegar. Tess as normal household vinegar can be used
instead of acetic acid for this test five percent vinegar or five percent
acetic acid solution is applied to the cervix and after one minute. The health
worker checks to see if it changes color when vinegar is applied to abnormal
cervical tissue white spots will appear so you can make an immediate assessment
of a positive or negative result white spots occur because the precancerous
cells have increased
protein normal cells
do not change color, the remain pink in this test.
I didn't is applied
to the cervix if cervical precancerous changes are present they will appear
well defined thick and mustard or golden yellow in color while the normal cells
of the cervix stains brown or black the results from these tests are
reported as negative
or normal positive. for pre-cancer or suspicious for cancer a negative result
means the woman has a normal cervix a positive result means the cervix has
pre-cancer cells which if not treated early can develop into cancer and results
reading suspicious. for cancer means the woman has changes visible on her
cervix that causes you to suspect cancer she will need to be referred for
diagnosis and treatment.
The test cannot
confirm a cancer diagnosis or the stage of cancer this has to be done by a call
pasta p biopsy and examination if a positive pre cancer diagnosis is made then
treatment can take place in the same visit as part of the screen and treat
approach this is more convenient for the woman the visual screening tests are
simple give immediate results and are easy to perform this means they can be
carried out by nurses or a health worker. These methods are very effective for
premenopausal women
but less suitable for postmenopausal women this is because the transformation
zone of these women is often inside the cervical canal and therefore not
visible the transformation zone is part of the cervix where precancerous
changes often occur due to the occurrence of false positives.

Some woman who test
positive do not have the disease this means that some women will get treated
unnecessarily if we caused them anxiety however VI a and really produce very
few false negatives so many women will be saved from developing cancer with
these relatively simple safe tests and treatment now it's time to hear about
the other two screening methods. First the Papanikolaou or Pap test the Pap
test involves collecting cells of the cervix using a spatula or brush these are
then smeared onto a glass
slide and immediately
faced with a solution to preserve the cells the sample must be carefully
labeled and sent to the laboratory, where it is stained and examined by a
trained health worker using a microscope this determines whether the cells are
normal or abnormal
and the extent of the abnormality perhaps have been used for a long time. in
some countries however they require good laboratory resources and quality
controls they have fewer false positives than the visual test but they have
more false negatives which means they are most useful in areas where animal
screaming.
as possible as samples
have to be sent to the laboratory it can be costly and the results are not
immediate the results will come back as negative positive for high-grade ore
low-grade lesions all suspicious for cancer the Pap test cannot confirm the
final diagnosis of the stage of cancer the fall screening test is the HPV DNA
screening. while all the other tests are detecting precancerous changes in the
cervix this method is used to detect the DNA of high-risk HPV in vagina or
cervical smears a sample of cells is collected from the cervix all vagina using
a swab or a small brush and plays in a container with a preservative solution.
The specimen can be
collected by the healthcare worker or by the woman herself by inserting a swab
deep into the vagina until it meets resistance and then turning it three times,
the sample is then sent to a laboratory for analysis. detection of high-risk
HPV does not necessarily mean that pre cancer or cancer is present it indicates
simply that the woman has a huge bv infection and that this if left. Untreated
can lead to cancer HPV testing has fewer false positives and false negatives so
the test will tell you more accurately who is at risk if the results are
positive the woman will still need to undergo one of the other cervical.
Screening tests to
establish if the HPV infection has led to the development of cervical
pre-cancer or cancer so those are the four screening tests used to detect
abnormalities on the cervix, now we will hear about what happens next all woman
should receive the results of the test well the negative or positive and
effective system for follow-up and treatment of women who test positive is an
important component for successful. cervical cancer prevention after a positive
result some women may require a car pasta p if there is one available alka
pasta p is the visual examination of the cervix vagina and vulva with a special
type of microscope which provides elimination and magnification allowing the
seller person to be examined application of dilute acetic acid highlights abnormal
areas and a visual analysis of the extent of the precancerous lesions can be
carried out if needed a biopsy can be performed at the same time using a punch
biopsy forceps small
pieces of tissue removed from the abnormal areas of the cervix.
The sample is placed
in a preservative labeled and then sent to the laboratory for analysis this
will confirm whether there is pre cancer or cancer and the severity and extent
so that appropriate treatment can be given , pasta p.m. biopsies should be performed
by properly trained health professionals once clearly diagnosed small
precancerous lesions can be treated with cryotherapy as part of the screen and
trees approach a woman with large. Lesions found with VI a of valley or high
grade lesions cloud with pap tests or coupee should be referred to a gana
colleges for procedures requiring more expertise before doing the cryotherapy
Presidio and VI a or a very test will need to be performed in order to identify
the abnormal tissue for removal sometimes both tests are carried out
cryotherapy eliminates precancerous areas on the cervix by freezing them.
This simple procedure
takes about 15 minutes and can be performed without anesthesia by trained
professionals who
are skilled in public
examination and cryotherapy to perform cryotherapy a speculum is inserted into
the vagina and abnormal areas of the cervix are identified by applying either
acetic acid or I adine that a highly cool metal discs called a cryoprobe is
applied to the cervix this freezes the surface
using carbon dioxide
or nitrous oxide gas the crier probe is applied to the cervix twice lasting for
three minutes each time with a five-minute saw or rest in between this is
called the double fries technique or the 353 freeze formula
Cryotherapy has a success
rate of around ninety percent for the treatment of small lesions cryotherapy
preserves the uterus and cervix so women can still have children in the future
for big
lesions are those
thought to be more serious than a loop electrosurgical excision procedure or
leap is used. Before any treatment it is important that the health worker
discusses the procedure and the potential side effects with the patient
after treatment, the
woman may experience mild pain and
cramping and a watery
discharge we should disappear within two weeks the cervix takes a month to heal
and it's important that the woman either abstains from sex or use a condom
during this
time the woman should
report to the health facility for investigation and treatment is she
experiences fever
severe abdominal
pain.
Foul smelling
discharge or lower back pain a follow up review should take place for weeks
after the procedure and
a further check out a
year later treatment by cryotherapy and leap is appropriate for precancerous
conditions if screening suggest there is a suspicion of cervical cancer then
the woman should be referred on for further investigation and treatment
treatment. would depend on the stage of the cancer the age and the general
health of the woman treatment options could include surgery and radiotherapy,
finally we hear about how important it
is to keep records
records should include every woman's clinical record appointments that have
been scheduled and those that have been kept or missed this can be a simple
paper record or computer-based with the exception of the Pap test, there are no
permanent samples of the screen test that can be reviewed later.
So it's important
that all screenings and results are recorded in a log book it is also important
to make sure that women receive their results whether they're positive or
negative and that women with positive results are followed up for treatment
remember screening
alone does not prevent cervical cancer
this Article has
introduced you to the principles behind cervical screening test treatments and
prevention and the
second film in the
series you will see a step-by-step guide to
perform in the visual
screening tests and remember screaming alone does not prevent cervical cancer
follow up and treatment are key to the prevention of cervical cancer yeah
