    Abstract

    Background

    Breast cancer is one of the most common types of cancer affecting women globally. It has shown increasing morbidity and mortality rates over the past years. Several screening methods ranging from simple breast self-examination to a highly sensitive test procedures for early detection and treatment are available, but uptake is a challenge. Lack of a national screening programme in the country makes available regional screening programme unsuccessful. This study aims to assess the factors affecting the uptake of breast cancer screening programme among female staff in a tertiary hospital, Southwest Nigeria.

    Method

    This descriptive cross-sectional study involves 375 participants selected by a stratified random sampling technique, with proportional allocation to population size and the use of a semi-structured questionnaire. Respondents were questioned on their basic knowledge of breast cancer symptoms, risk factors and treatment, over a score of 50 and above, were set as the cut-off mark to determine good knowledge of breast cancer. Patients attitudes towards breast cancer screening as well as factors affecting uptake were also measured. Descriptive statistical analysis was done using SPSS-20 while the predictors of the uptake of screening were determined using logistic regression at p ≤ 0.05.

    Results

    There were 360 respondents, comprising of 13.3% clinical and 86.7% non-clinical female staff within the age bracket of 20 to 58 years (38.2±0.42 years). Out of the respondents, 97.8% have heard about breast cancer but only 52.3% had been screened while 65.5% had Good knowledge of breast cancer. Positive attitude to breast cancer screening was displayed in 52.5% while over 90% claimed to be practicing breast self-examination. Only 36.1% of respondents above 40 years old have had mammography done. Most frequent barriers to screening uptake include cost, poor accessibility to screening facilities, shyness (unfamiliar screener), unavailability of female doctors, careless attitude, fear of cancer and other more pressing family problems. Using logistic Regression at p ≤ 0.05, females with a negative attitude, young unmarried (less than 30years) and lack of easy accessibility to screening facilities were significant factors affecting uptake of breast cancer screening services.

    Conclusion

    Due to knowledge-uptake gap of breast cancer screening revealed in this study. It is therefore obvious from these findings that a concerted effort is needed to actively remove these barriers by repeated education, training and re-training strategies among health workers and to improve their uptake and level of advocacy and campaign for breast cancer screening among their patients and clients.

    Results

    Result Socio-Demographic Characteristics

    Among the 375 participants recruited into this study, 360 returned a completed questionnaire giving a response rate of 96%.

    The result from Figure 1 below shows the distribution of the study participants into 48 (13.3%) clinical and 312 (86.7%) non-clinical staff members and the socio-demographic characteristics of the respondents. The largest proportion of the respondents 177 (49.2%) were within the age group 30-39 years while the lowest proportion of 39 (10.8%) was within 20-29 years. The mean age of all respondents was 38.2±0.43 years, with age range of between 20 and 58 years. All the respondents were females, the highest educational status was first degree (43.3%) while 21.4% had postgraduate degrees, the majority were married (87.2%), while the remaining 25.3% had no child and included those that were single and those that were married but with no children yet.

    Awareness and Source of Information on Breast Cancer

    Majority of the respondents, (97.8%) had heard of breast cancer while only (2.2%) were ignorant of the disease. Most of the respondents got their information from their relatives (41.9%) and health workers (30.6%). Other sources included Neighbours (11.1%), friends (10.3%), and media (4.7%).

    Knowledge of Breast Cancer

    Regarding the risk factors for breast cancer, 282 (78.3%) of the respondents stated that breast cancer is hereditary, 266 (73.9%) understood that breastfeeding decreases the risk, 262 (72.8%) reported that risk increases with advancing age while some said painless breast lump is a risk factor (66.9%). Surprisingly, 130 (36.1%) of the participants claimed magic and evil spirit been risk factors also.

    The knowledge on the commonly presenting symptoms of breast cancer was also assessed, 284 (79.8%) of the respondents reported breast lump, 213 (59.2%) bloody nipple discharge, 208 (57.8%) disparity in breast sizes, 197 (54.7%) ulcer on the breast while 186 (51.7%) admitted pain in the breast. Other women stated that skin discoloration, recurrent boils in the breast and foul-smelling nipple discharge are symptoms.

    There was a good knowledge of the available screening methods for breast cancer among the respondents. Majority alluded to breast self-examination (295, 81.9%), mammography (225, 62.5%) and clinical self-examination (186, 51.7%). The staff of age 40 and above also have good knowledge of mammography (117, 81.2%).

    The respondents also had good knowledge of the available forms of treatment of breast cancer, 243 (67.5%) surgical treatment, 237 (65.8%) medical treatment and 193 (53.6%) radiotherapy. Alternative medicines were considered in 49 (13.6%) of the respondents while 115 (31.9%) said no specific treatment modality is available.

    Majority of the respondents, 276 (76.7%) also stated that early detection of breast cancer can improve outcome.

    Concerning the knowledge score of the respondents on breast cancer screening, 213 (61.9%) had good knowledge of breast cancer while only 131 (38.1%) had poor knowledge.

    Attitude to Breast Cancer Screening

    Most of the respondents, 346 (96.1%) have positive attitudes toward breast cancer screening while 14 (3.9%) have negative attitudes toward the screening. The participants above 40 years, 141 (97.9%) also have good attitudes to the screening.

    The Practice of Breast Cancer Screening

    Only 155 (43.1%) of respondents have had a breast cancer screening (Figure 1). Reasons given by respondents for non-uptake of screening services included indecision in 42.5% of all respondents, lack of information (22.9%), and feeling of good health (17.7%) (Figure 2). Most of respondents 224 (90.0%) said they practiced breast self-examination (Figure 3), while a greater proportion (139 62.3%) said they had gone for clinical breast examination before. Only 107(29.7%) reported having done MRI, 43 (7.8%) reported having done both mammography and biopsy for histology, while the least reported breast screening procedure done by respondents was ultrasound (32, 8.9%). However, of the respondent's age 40 and above (who are eligible for mammography screening and made up 40% of the respondents), only 36.1% have had mammography done (Figure 3).

    The table also shows that there is a significant relationship between the education level of respondents and respondents’ uptake of breast cancer (p = 0.017). This shows that the uptake of breast cancer screening is associated with the level of education.

    As regards the association between the number of children owned by respondents and their uptake of breast cancer screening services, the result on Table 1 shows that the uptake of screening programmes was statistically independent of the number of children owned by the respondent (p = 0.239).

    Awareness of Breast Cancer Versus Uptake of the Screening Programme

    As regards the knowledge of breast cancer and the uptake of the screening programme, there is a higher proportion of the respondents, 352 (97.8%) who have had information on breast cancer but did not take up its screening services especially the mammography. This difference though, was not statistically significant (p =0.190).

    Family History of Breast Cancer Versus Uptake of the Screening Programme

    As regards the family history of breast cancer and the uptake of the screening programme shown in Figure 4 below, a greater number of respondents who had a family history of breast cancer did not go for any screening. This relationship was statistically significant (p <0.001).

    Knowledge of Importance of Early Detection versus the Uptake of Breast Cancer Screening

    (Table 2) shows a test of significant between knowledge of the importance of early detection of breast cancer on uptake of breast cancer screening services. The result shows that uptake of breast cancer screening services was dependent on knowledge of the importance of early detection of breast cancer (p < 0.001).

    Majority of the respondents, 276 (76.9%) had good knowledge of the importance of early detection of breast cancer, its management, and its screening (139, 50.4%). Out of 65 (18.1%) respondents who had poor knowledge on the importance of early detection of breast cancer and its management and the 18 (5.0%) who had poor knowledge of the importance of early detection of breast cancer on its management, only 10 (15.4%) and 5 (27.8%) had breast cancer screening respectively.

    Attitude to Breast Cancer Screening Versus the Uptake of BSE, CBE, and Mammography

    (Table 3) shows the relationship between attitudes of the respondents on uptake of different forms of breast cancer screening which include Breast Self-Examination, Clinical Breast Examination, and mammography. The result reveals a high uptake for BSE 146 (94.8%) and CBE 92 (61.3%) among respondents who had a positive attitude to breast cancer screening, but a low uptake for mammography, 22 (14.6%).

    The study further test if respondents ‘uptake of BSE, CBE and mammography was dependent on their attitude towards breast cancer screening. The result shows that respondent’s uptake of BSE was dependent on their attitude (p = 0.002), while their uptake of CBE (p = 0.765) and mammography (p = 0.108) was independent of their attitude.

    Determinants of Breast Cancer Screening Uptake

    (Table 4) shows the result of the logistic regression performed to ascertain the effects of socio-demographic factors, attitude, and awareness of Breast cancer on the likelihood that respondents will go for breast cancer screening. The model explained 18.5% (NagelkerkeR2) of the variance in breast cancer screening uptake and correctly classified 66.2% of cases.

    Statistically significant at p ≤ 0.05

    Clear observation on Table 4 shows that attitude has a statistically significant correlation with uptake p ≤ 0.001. This implies that respondents with a negative attitude are less likely to take up breast cancer screening services (coefficient is negative). Those of age, number of children, education, barriers, and awareness were not statistically significant at p > 0.05.

    Discussion

    Discussion Discussion of Findings

    This study examined the knowledge, attitude and factors that affect the uptake of breast cancer screening among female health care workers in a tertiary health institution, Southwest, Nigeria. Even though the participants were a sample from among the female staff of the health institution, the sample, as a cross-sectional pool, should reflect what could be expected of the entire female staff.

    Knowledge of Screening

    The findings from this study highlight the major factors affecting the uptake of breast cancer screening among the respondents. The study demonstrated that the majority of the respondents have heard about breast cancer. These may be because the respondents were hospital staff which cannot be compared with a lower rate of about a third among tertiary school female student s population in Ibadan and women in a local community in the same environment. 1213. This appears to be a problem of developing countries as studies done in Tunisia and Jamaica in 2007 1415 showed a similar pattern of the low level of awareness.

    Women in developed countries also appear to be more aware of cancer of the breast and the screening programmes as indicated in a study done among Cambodian, Laotian, Thai, and Tongan women which reported above three-quarters of their women with good knowledge on Breast cancer screening 16.

    The level of knowledge of the availability of a screening programme for breast cancer was found to be high in this study. This also may reflect the respondents being health staff. Generally, the level of knowledge was found to be low for most developing countries and among the non-health workers. 1718.

    About half of the respondent's sources of information on cancer and screening were mainly from health workers. Surprisingly, this low proportion may reflect the low drive for information dissemination among the health workers on cancer screening despite high knowledge. This is unlike in the developed areas where the health workers have a mandate to ensure the provision of more effective health education and information about prevention and screening to be able to elicit the fears, prejudices and priorities of patients in these areas that may serve as barriers to uptake of the programmes 19.

    In this study, the respondents have a fair understanding of the symptoms associated with breast cancer in which painless lump in the breast and bloody nipple discharge were highly considered.

    The most common risk factors for breast cancer mentioned include hereditary, painless breast lump, and advancing age for breast cancer. This finding is also similar to the finding in a study done among Cambodian, Laotian, Thai, and Tongan Women 16. In this study, about one-fifth of the respondents could not identify any risk factor for breast cancer.

    The knowledge of risk factors is an important element in the prevention of breast cancer. Knowing the modifiable risk factors can make a woman avoid them and hence prevent disease occurrence. Surprisingly, one-fifth of the respondents still believe in the evil spirit and magic being a risk factor for breast cancer.

    Women's knowledge on the importance of screening for breast cancer to detect premalignant lesion was also good, only a few were not sure of screening importance. The majority identified BSE as the breast cancer screening method, however, some also recognized CBE and mammography. This pattern is also seen in the similar studies done among health workers in Tunisia and some developed countries 2021. Among the respondents, about half believed that any woman of age 18 years and above is eligible for screening.

    Attitude Towards Screening

    This study shows a good attitude of the respondents to seek medical help when noticed a lump or other associated symptoms though some will allude to pray unto God.

    This study also looked at the respondent s attitude to breast screening programmes. Overall, more than half of the respondent had a positive attitude towards the screenings.

    Perception of susceptibility to the development of breast cancer was found to be another factor that can affect screening behaviour. Less than one-quarter of the respondents wrongly expressed lack of personal susceptibility to cancer and therefore believed they didn't need to have any screening done.

    The Practice of Screening Programmes

    This study also looked at the practice of screening programmes among the respondents. In this study, 94%, 58% and 11% of the respondents had practised BSE, CBE and mammography before while only third of respondents above 40 years old have had mammography done. This pattern of low uptake of mammography is usually observed across African countries including among the female health workers despite their good knowledge and also among Vietnamese women 16 and 22.

    There were huge differences when comparing the practice in African countries to those in developed countries. In the UK, multiple strategies were in place to capture all eligible women for the screening programme despite the high uptake level 23. In this study, the majority of women in the age group 30-39 years uptake the screening more unlike the younger women in the developed countries, who tend to be screened earlier based on the high level of awareness and the availability standard national programmes on screening. However, the small proportion of women in the age group 20-29 years taking up the screening for breast cancer could also be due to common belief that breast cancer is commoner in older women except for people with positive family history.

    Even though there was no significant association between age and awareness of breast cancer, however, respondents at all ages practice BSE while the least practised is mammography even among the age group above 40 years which is unlike some studies where increase uptake was reported among this group 1821.

    The relationship between marital status and uptake of BSE was not significant (p> 0.05).

    Factors Affecting the Uptake of the Screening Programmes

    Barriers to the uptake of breast cancer screening have been shown to exist in many countries. The greatest barriers identified against breast cancer screening uptake include none affordability/accessibility, shyness (because of familiarity with the screener) and unavailability of female doctors most of the times. Other factors include careless attitude, fear of cancer and other more pressing family problems. Similar barriers are common to several local and hospital-based studies even in this environment 122425.

    These findings identify the need of providing adequate information about the importance of breast cancer screening to the health workers in different department to eliminate these barriers. It is therefore obvious that a concerted effort is needed to actively remove these barriers by repeated education, training and re-training strategies to improve their uptake and level of advocacy in campaigning for screening among their patients and clients.

    The correlations between the uptake of the breast cancer screening and age are significant with the uptake of mammography (p < 0.0001) and with various factors preventing utilization of screening programmes (p = 0.016).

    Conclusion

    Conclusions

    The result of this study provides a comprehensive picture of the knowledge, attitude and practise of the screening for breast cancer, including the locally available screening procedures, various barriers to uptake of the screening programmes and the barriers to the utilization of the locally available screening procedures. Various factors identified in this study that affect the screening programme are modifiable. This could be addressed through multiple channels which may include detailed and regular sensitization and awareness programme for all staff on epidemiology, risk factors, symptoms and management of common cancers. Most especially, special emphasis should be made on the available screening programmes and the importance and necessity of uptake with a primary aim of addressing the barriers.
