The prevention of any illness can be primary or secondary. The  previous involves taking action on the determinants of the illness to  prevent it from occurring. The second involves the early detection of  disease, followed by acceptable interventions to stop its progression.
there  has been substantial media PR about the prevention of cervical cancer  during the past half a year. Almost all of it has focused on the human  papilloma pathogen ( HPV ) vaccine, which has been called a cervical  cancer vaccine, though there isn't any such vaccine available anywhere  in the world.
Cervical smears have led to a steady decline in the  incidence and mortality of cervical cancer in developed countries which  have introduced population wide screening programmes.
Yet cervical  smears have scarcely been discussed in the media target cervical cancer  prevention. This is despite the indisputable fact that only 43% of  Malaysian women have ever had a cervical smear in their lives ( national  Health and Morbidity Survey 2006 ) although cervical cancer is the  second most typical cancer in women ( countrywide Cancer Registry 2003  ). There is an overuse of cervical screening by ladies who are younger  and/or who are at low risk.
The beginning of cervical cancer  begins with changes in the squamocolumnar junction of the cervix where  the flat squamous epithelium of the exocervix meets the columnar  epithelium of the endocervix. The proportion of the cell nucleus to the  cell size is increased in the epithelium in the pre-cancer phase of the  illness.
There is a correlation between the induction of these  changes and HPV infection. The pre-cancer changes are called cervical  intraepithelial neoplasia ( CIN ). CIN is graded as mild ( CIN 1 ),  moderate ( CIN two ) or harsh ( CIN 3 ). The CIN moves on from mild to  moderate to dreadful illness and then invasive cancer over seven to  twenty years. There are customarily no symptoms during this progression,  which can be perceived by cervical smears.
Cervical cancer has a  pre-cancerous phase lasting about 7 to 20 years before the standard  cells change to cancer cells. As the danger factors of cervical cancer  are known, behavioral interventions can be brought to prevent its  development.
Regular pelvic exams and cervical smears would detect  most pre-cancerous changes in the cervix. With treatment, the  development of aggressive cancer would be stopped. Even if there's  aggressive cancer present, it is going to be perceived at an early,  curable stage.
The cervical smear is a screening test that  uncovers pre-cancerous cells. This enables doctors to refer those with  unnatural changes in the cervix for further inquiry and treatment. It  must be emphasized that the cervical smear isn't a diagnostic test.
It  involves taking a small sample of cells from the cervix using a brush  or spatula. The cells are placed on a glass slide or into a container  and sent to the lab for minute examination.
Cervical smears are  recommended for all women, although if the woman hasn't had sex. The  likelihood of cervical cancer in such girls is thought to be low, but it  can still occur. Regular pelvic exams and Pap smears should be done  once sexual activity starts. The frequency would rely on the findings  and the woman's risk profile.
The use of cervical smears in  widespread population screening in many developed nations has ended in a  marked decrease in the incidence of cervical cancer. It's critical that  patients and/or their mom and pop are informed the vaccines provide  cover against certain HPV types and not cervical cancer.There are a  couple of vaccines available. One vaccine acts against 4 HPV types and  the other against 2. They prevent development of the HPV infection. As  HPV infection is a big risk allow for the development of cervical  pre-cancer, vaccination would forestall some of its development.
Behavioral  interventions have an important role to play and they are comparatively  economical. Yet they don't seem to be given the same press as that of  HPV vaccines. The misconception of many patients and/or their mom and  pop that HPV vaccines are the wizardry bullets to get shot of cervical  cancer needs to be addressed by health messages that reflect the  actuality of cervical cancer prevention.
In short, there needs to  be bigger stress by policy makers and healthcare execs on the proven  systems of cervical smears and behavioral interventions if there is to  be any important impact on reducing the incidence and mortality of  cervical cancer.
