Intro
A precancerous cervical lesion, which is also called an intraepithelial lesion, is an
abnormality in the cells of the cervix that could eventually develop into cervical cancer.
1
Cervical cancer is a crucial point of action for any cancer control program
because of the burden of the disease, and the possibilities for effective prevention
via screening.
2
It is historically classified as adenocarcinoma and squamous cell carcinoma
in 99% of women with squamous cervical carcinoma caused by Humans Papillomavirus
(HPV) infection.
3
Cervical cancer is the leading cause of death in women. Worldwide, cervical cancer is
the fourth leading cause of death in women.
4
By 2020, an estimated 604000 women have been diagnosed with cervical cancer
worldwide and an estimated 342,000 women have died of the disease.
3
Globally, cervical cancer has an occurrence rate of 371,000 cases and a death
rate of 190,000 with 80% of the cancer of the cervix death occurring in
resource-limited countries. The maximum rates are found in Central and South
America, East Africa, South, and South-East Asia, and the Western Pacific. The
problem is mainly worse in sub-Saharan Africa.
1
In Africa, 80,400 women were diagnosed with cervical cancer each year and it
is the second most common cancer in the region. Furthermore, 50,300 women die each
year from the disease and it is the leading cause of death from cancer. In
sub-Saharan Africa, cervical cancer accounts for 22.5% of all women with cancer, and
the majority of women with cervical cancer live in rural areas. 5 , 6 Ethiopia ranked 14th led by
Malawi among the East African Countries. In Ethiopia, about 7095 new cervical cancer
cases are diagnosed annually which makes it the 2nd leading cause of female cancer
and the 2nd most common female cancer in women aged 15-44 years according to an
estimate 2012. 7 , 8
According to World Health Organization (WHO) estimates, cervical cancer is expected
to kill more than 443,000 women by 2030, with a high rate (over 98% of deaths)
believed to occur in developing countries (especially in Sub-Saharan Africa (SSA).
9
Non-communicable diseases such as cervical cancer cause devastating effects
in developing countries.
5
Cervical cancer is the most common cancer in 23 countries and is the leading
cause of death in 36 countries. Most of these countries are in sub-Saharan Africa,
Melanesia, South America, and Southeast Asia.
10
Precancerous lesions can be progressed to cervical cancer and the risk for
the development of cervical cancer if there is missed the chance of early
identification of the precancerous lesion and its risk factor.
11
It can be prevented, unlike other reproductive cancers through effective
screening programs.
12
According to an estimate in 2012, there were about 4732 cervical cancer
deaths which occurred annually making cervical cancer the 2nd leading cause of
female cancer deaths in Ethiopia. As well as being the 2nd leading cause of cancer
mortality in women aged 15-44 years. This implies there will excessive life loss due
to the disease unless prompt intervention like screening and vaccination is undertaken.
8
Early screening and vaccination are some prevention strategies for cervical
cancer. However, the risk of death from complications related to cancer of the
cervix may be mainly affiliated to health problems over the course of a woman’s life
in low income countries.
13
Vaccination can be viewed as primary prevention, with screening as secondary prevention.
12
Even though the cause for many cancers remains unknown, established cancer causes
include external factors like lifestyle, such as tobacco use and excess body weight,
and non-modifiable judged as internal factors, including inherited genetic
mutations, hormones, and immune conditions are contributors.
14
The peak age of incidence was between 40 and 49 years. Most of the cases were
found in Addis Ababa, where the hospital is situated. An increase in the trend of
cervical cancer cases was observed.
2
In addition, in Ethiopia, early sexual activity, high HIV prevalence, and low
socioeconomic status may place women at risk for cervical cancer.
15
It is estimated that about 1-2% of women have CIN2 + each year. This rate is reported
to be higher for HIV-positive women, at 10%. 1 - 5 , 16 In high-income countries,
regular Pap smear tests have been shown to reduce the risk of developing cervical
cancer, by detecting malignant mutations.
17
As the problem is escalating in low and mid-income countries, interventions
like using visual inspection with acetic acid has been revealed to be effective for
screening in precancerous lesion low resource settings.
18
Cervical cancer is preventable, however many women in low-income countries do not
have access to effective screening programs. Ethiopia has no standard policy or
protocol for cervical cancer screening, rather it is patchy or inconsistent.
Ethiopian women typically present for cancer care at a late stage in the disease,
where treatment is likely ineffective.
19
There are no specific symptoms and no clinical features indicating the
presence of a CIN. Many of these lesions, however, may become white when 3-5% acetic
acid is added and possibly iodine-negative in the use of Lugol’s iodine solution, as
the CIN epithelium contains little or no glycogen.
20
Like that of colorectal cancer screening, this procedure can help to prevent
cervical cancers by giving opportunity for early identification and removal of
precancerous lesions. It also provides the chance to identify as early as possible,
when treatment is less extensive and more likely to be successful. Furthermore,
screening is known to contribute in decrement of death from cancers including
cervical cancer.
14
However, lack of funding for diagnostic services, low awareness of testing,
and lack of trained health professionals are also major challenges in diagnosing and
treating cervical cancer.
21
Reducing the magnitude and tackling the factors related with precancerous lesion is
very important. As it is very crucial to produce significant decreases in incidence
and mortality from precancerous lesion, barriers should be identified. Therefore,
this study is aimed at determining the magnitude of this lesion within the study
area and factors contributing to the problem.
22
Every woman has the right to be screened for cervical cancer at least once in
her lifetime. However, in resource-poor settings, 30–49-year-old women comprise the
target audience because cervical cancer is rare in women under 30 and most common in
women over 40 years. Screening younger women will detect many lesions that will
never develop into cancer, will lead to considerable overtreatment, and is not
cost-effective. 1 , 23 In the same manner, the World Health Organization set priority
to be given to screening women aged 30-49 years in the general population of women.
23
In Ethiopia according to the population census of 2013 EFY/2020/21 G.C
projected estimate of women aged 30-49 years comprises approximately 19.2% of the
total population.
1
To the best of author’s knowledge, prevalence, and factors for precancerous
cervical lesions, have not been studied yet in study area. Therefore, this study
will serve for clinicians, policy makers, and program planner’s designers as a
resource for the design of appropriate interventions to decrease cervical cancer in
areas like vaccination, early screening, and awareness creation. Further, the
results of the study may serve as baseline information for future research.

Among the study participants interviewed, only 217 (64%) had ever heard about
precancerous cervical lesions of which 56.6% replied media is a source of their
information, and 75(34.2%) reported health care workers. Around three fourth
(77.3%) claimed as having multiple sexual partners as a risk for precancerous
cervical lesions. Early sexual practice (<18 years) and cigarette smoking as
risk factors for precancerous cervical lesions were reported by 67% and 60.8% of

Among the study participants, 145(42.8%), 143(42.2%), and 157(46.3%) had strongly
agreed that cancer of the cervix is highly prevalent in Ethiopia, precancerous
cervical lesion affects any woman, and precancerous cervical lesion can be
prevented, respectively. Almost 50% of the study participants strongly agreed
that having precancerous cervical lesion screening is not harmful and that the
service is given free of charge. In general, 229(67.6%) of the respondents had a

Discussion
The findings of this study are in line with the results of a study from the city of
Arba Minch and the Zuria region (27.7%) and are higher than those reported in Easter
Ethiopia, Harar (18.5%), three referral hospitals of Amhara region 20.2%, and Jimma
(12.9%). 3 , 5 , 10 , 13 Furthermore,
the findings were significantly higher than systematic reviews conducted in Ethiopia,
24
Southern Ethiopia 22%, 25 - 26 Dessie 6.9%, Waldia and
Dessie 9.9%,
27
Almeda textile factory in North Ethiopia 6.7%
28
and Rwanda.
18
This reveals that the findings recommend raising of a screening strategy for
cervical intraepithelial neoplasia for all women.
13
In this study, 63.4% of study participants were well-informed about cervical cancer.
The findings were higher than the study results in Butajira and Wolita of Ethiopia.
On the other hand, the study also revealed that 67.6% of women interviewed had a
positive attitude toward cervical smear screening under the results reported in
Bishoftu town. 16 , 17 , 29
Participants with a diagnosis of menstrual irregularity had a statistically
significant higher odds of association [AOR=2.29(95%CI: 1.29-4.04] for being
diagnosed with a precancerous cervical lesion of the cervix, which is in line with
research done in Debre -Berhan University.
22
This might be a reason of other causes of abnormal menstruation including
uterine cancer or cervical cancer.
20
As well, sometimes cervical cancer mimics menstrual bleeding. The patient may
notice a longer or heavier menstrual cycle than usual or spotting or bleeding
between periods
24
Women having STI had 3.5 times higher odds of developing precancerous cervical
lesions compared to women with no history of STI [AOR) = 3.46(95%CI:1.94-6.18)],
which is similar to research conducted in the Debre Markos town,
30
Southern Ethiopia,
25
and three referral hospital in Amhara region.
5
This association might be due to that the fact that cervical cancer occurs in
the cervix, which is the entrance to the uterus. More than 90% of cervical cancers
develop due to persistent infection of the human papillomavirus (HPV), which is most
often transmitted through sexual intercourse.
21
It is clear that STI are a result of having sexual partners. In another way,
having multiple sexual partners escalates the risk of getting HPV, and in turn, can
lead to the development of cervical pre-cancer lesions.
13
As well, it is clear that nearly all cases of cervical cancer result from
infection with HPV, and the prevention of cervical cancer includes screening and vaccination.
12
Women having a history of bleeding after sexual intercourse were more likely to have
precancerous cervical lesions [AOR=2.88(95%CI: 1.43-5.78)] compared to their
counterparts. This is in line with a study in Beijing.
31
Bleeding during or after sex can be alarming, especially if the mothers were
not menstruating.
32
The most likely causes include a sexually transmitted infection, benign
polyps, cervical ectropion, atrophic vaginitis, endometriosis, trauma, and cancer.
33
The results suggest that to prevent precancerous cervical lesions one must
consider changes of lifestyle and sexual behavior.
34
Women with parity greater than or equal to five had 2.4 times higher odds of
developing precancerous cervical lesion compared to women with parity less than five
[AOR=2.41(95%CI: 1.23-4.75)], which is in line with Johannesburg South Africa,
35
this might be due to that high parity increases the risk of squamous-cell
carcinoma of the cervix among HPV-positive women. A general decline in parity might
therefore partly explain the reduction in cervical cancer recently seen in most countries.
36
Women with an unfavorable attitude had 2.2 times higher odds of developing
precancerous cervical lesions compared to women with a favorable attitude
[AOR=2.15(95%CI:1.21-3.83)]. This is in line with research done in Hawassa town
36
and an overall score of attitudes was 67.6%. This finding was lower than
research conducted among Adama Science and Technology University Female Students
which was (71.7 %). This discrepancy might be due to the fact that the
study area was urban and also might be due to the educational status of study participants.
37
Conclusions
Precancerous cervical lesions continue to be a significant public health concern in
Ethiopia. It will remain a cause of death of women unless effective screening
methods like VIA and vaccination to HPV are scaled up. Furthermore, having history
of menstrual irregularities, STI, bleeding after coitus, parity greater ≥5, steroid
use, and having unfavorable attitude towards screening factors are significantly
associated with occurrence of precancerous lesion. This implies that clinicians can
play a pivotal role in the prevention of advancement of the lesion to cancer as
majority of the factors can be identified during early. Therefore, effective
prevention approaches have to consider these factors for the control of cervical
cancer in early phase of lesions.

This study was conducted in selected hospitals of West Wollega, which is found in
Oromia National Regional State, located at a distance of 441 km from Addis Aba.
It has a total population of 1,951,933 (Urban %13 Rural 87%). Five government
hospitals, two NGO hospitals, 67 health centers, and 560 public health
facilities are currently functional. Data were collected from January 1-February
20/2022. The participants were selected from all women of age 30-49 years’
living in the West Wollega zone, while all selected women of age between 30 and
49 years attending pre-cervical cancer screening at West Wollega Hospitals and
selected health centers were studied by institutional-based prospective analytic
cross-sectional study design was employed.
The sample size was calculated using a single population proportion formula;
considering 27.7% as the prevalence of pre-cervical cancer among clients
screened in Southern Ethiopia,

The sample size was found to be 308. By adding a 10% non-response rate the final
sample size is 339.Hospitals and health centers providing routine cervical
cancer screening and treatment using VIA and cryotherapy services were
purposively selected . Women aged 30-49 years in four
hospitals and five selected health centers were 125,250 (Gimbi General

and Aira General Hospital=18,474) (five selected health center =40,643. The
calculated sample size was allocated using probability proportional to size
(PPS) and finally convenient sampling was used to select the study subjects.
Data were collected through face-to-face interviews with a structured
questionnaire that was initially adapted from previous studies.

The questionnaire was prepared in English, translated to Afan Oromo, and
then back to English to check the consistency. Ten BSc nurses and five
supervisors were assigned for data collection and supervision.
One-day orientation was given for data collectors and supervisors to ensure the
quality of the field operation by principal investigators. Supervisors
supervised the data collection process on daily bases and check the quality of
collected data. The data collection tool was pre-tested on 5% of the sample at
Arjo health center. Based on the findings and feedback obtained from the
pre-testing process, a modification was made to the questionnaire.
The data were entered into Epi-data version 3.2 and analyzed by SPSS version 25.0
for further analysis and interpretation. Descriptive analysis was carried out
for each of the variables to check frequency, distribution, and missing values.
Variable with a p-value of <.25 on bi-variable analysis were entered into a
multivariable logistic regression to identify predictors of pre-cancerous lesion
of the cervix. The odds ratio at 95% confidence intervals was used to quantify
the degrees of association. Results with a p-value ≤.05 were considered as being
statistically significant
A positive VIA - as “sharp, distinct, well-defined, dense (opaque,
dull, or, oyster white) acetowhite areas with or without raised margins,
abutting the squamocolumnar junction in the transformation zone” or “strikingly
dense acetowhite areas in the columnar.
