I am not a public health expert nor
a specialist, the reason for me to write this article is because I am concerned
that people (died and )might die of the preventable cause.
So
it is cervical cancer that I am going to throw a little light and the ways to prevent
it. Cervical cancer affects the cervix of uterus in the
female reproductive system. In Bhutan, cervical cancer is the
most common cancer diagnosed in women. More than half are diagnosed in late
stages, leading to high mortality. The
morbidity and mortality associated with this cancer has impact not only on the
life of these women, but also on their families.

A woman with cervical cancer lives with bleeding, foul smelling discharge, leaking urine/feces or severe pain for many months. She dies when she is still socio-economically productive leaving behind children who are small or dependent. Besides, the government spends a lot of money getting these patients treated in centers outside Bhutan. Cervical cancer is still the most common cancer referred for radiation. This is a cancer that is not only curable if diagnosed early, but is also preventable if detected early, with availability of good screening program.
Risk
Factors
ü Early age at marriage is one
of the most important risk factors.
ü Multiple sexual partners increase
the risk of exposure to HPV infection.
ü Low socio-economy and low education:
Women
of low socio-economy are more likely to either not enroll in school or drop out
early leading to early marriage and have more children. Due to low literacy,
they are also less likely to participate in screening due to ignorance and lack
of awareness.
ü Smoking: Nicotine
and by products of smoking are thought to increase a woman’s relative risk for
cervical cancer because their concentration in the cervical mucus decreases the
immune capability of the cervical tissue.
ü Immuno-suppression: Immuno-suppression
due to any reason leads onto persistence of HPV infection with more likelihood of
developing cellular atypia. HIV positive women are at higher risk of developing
cervical cancer. Cervical cancer is one of the AIDS defining cancers.
ü Lack of screening program: Lack
of an effective screening program also acts as a risk factor. Women who
regularly undergo screening and adhere to follow up and treatment are unlikely
to get cancer compared to those who never do it.
Symptoms of cervical cancer;
· Abnormal
vaginal bleeding;
· Excessive
or foul smelling vaginal discharge;
· There
may be urinary frequency and backache;
· In
advanced cases, there may be:
o
Pain in the pelvic region or lower
limbs;
o
Swelling of lower limbs;
o
Renal failure in late stages;
o
Passage of urine and feces from vagina;
Cervical cancer may remain silent for many years till it is well
advanced. Pap smear can help in early diagnosis
and treatment. |
Cervical cancer can be
prevented by vaccination against HPV (currently HPV vaccination is provided to girls
in class VI ) and early detection through pap smear screening.
Pap smear is a proven method for
cervical cancer screening. Pap smear studies the cells leading to
identification of women with abnormalities in the cervix. In Bhutan, Pap smear
screening services are available in BHUs and Hospitals. However, despite the
free screening services, incidence and mortality due to cervical cancer did not
change significantly over the past years. One of the reasons for this could be lack
of awareness among women on this service. Even if women are aware, some do not
avail the service. Some of the reasons I often hear is “I feel shy”. ‘I am scared it might be painful’. ‘I have no time’
If you are shy; just know that
cervical cancer is even more painful than your shyness. It only takes 3 to 5
minutes to get a Pap test and it’s not a very painful procedure.
When should women get Pap smear done?
·
Pap smear should be done 7 to 10 days
after menstruation stops;
·
In women with amenorrhoea or in
menopause or who had hysterectomy, it can be done any time;
·
In women who have delivered or had an
abortion/miscarriage, it should be done after three months.
In Bhutan, target population for Pap smear is all women
between 25 to 65 years of age regardless of HPV vaccination status. All women
who are or were sexually exposed should participate in screening or do Pap
smear
