A national survey to assess breast cancer awareness among the female university students of Pakistan.

The incidence of breast cancer is increasing in Pakistan as well as globally. Awareness of women about breast cancer plays a cornerstone role in its early detection, better management, and prevention. Keeping this in mind, a cross-sectional study was carried out to assess the awareness of female university students about breast cancer's risk factors, signs and symptoms, and breast cancer examination. The data was collected from female university students studying in Pakistan. A total of 774 participants completed the survey and recorded their responses on an online pre-tested self-administered questionnaire. Only 29.8% of the participants have identified breast cancer history in their first-degree relatives as a risk factor. Moreover, 14.1% of the participant considered that the use of oral contraceptives for more than 5 years can increase the risk of developing breast cancer. In addition, inward pulled nipple, wounds around the nipple, and abrupt changes in the breast size were considered as the sign and symptoms of breast cancer by 25.2%, 25.7%, and 31.7% of the participants, respectively. Moreover, only 20.9% of the participants identified the correct year for starting breast cancer examination and 44.4% of the respondents marked that mammography should be initiated after 40 years. Overall, the university female students of Pakistan were poorly aware of breast cancer's risk factors, signs and symptoms, and breast examination. This study has highlighted the need for initiation of aggressive strategies regarding breast cancer awareness in both the literate and illiterate female population of Pakistan.

Introduction

Breast cancer is a disease in which breast cells start an uncontrolled growth and produce an undifferentiated cell mass [1]. The American Cancer Society (ACS) broadly divided breast cancer into in-situ and invasive breast cancer [2]. The in-situ breast cancer starts in the milk duct and stay it locally. This type of breast cancer includes ductal carcinoma in-situ (DCIS) which is considered as a non-invasive or pre-invasive breast cancer. While invasive breast cancer has the potential to spread into the surrounding breast tissues and includes invasive ductal carcinoma and invasive lobular carcinoma [1, 2].

It has been reported that increasing age is highly associated with the incidence of breast cancer [3]. Additionally, women having a family history of breast cancer, are more prone to the development of this cancer [4]. Reproductive factors like early menarche, late menopause, late age at first pregnancy, and low parity can also increase the breast cancer risk. The delay in menopause each year increases the risk of breast cancer by 3% [5-7]. Moreover, the exogenous and endogenous estrogen is significantly associated with the risk of breast cancer. The main source of exogenous estrogen is oral contraceptive and hormone replacement therapy. This medication results in enlarged and tender breasts [8]. The risk of breast cancer is slight higher in women using oral contraceptives as compared who never used them [5]. The use of this medication can over-stimulate breast tissue, and could increase the risk of breast cancer. Moreover, the higher fat and low fiber diet can play role in the development of breat cancer [3, 5, 9, 10].

Breast self-examination (BSE), clinical breast examination, and mammography are the most widely used screening techniques [11]. BSE is a screening method for early breast cancer detection that can be performed at home. This is a basic, cheap, straightforward, and efficient approach for examining breast tissue for physical or visual abnormalities. BSE improves women’s chances of treatment by enhancing their odds of survival [12]. Despite advancements in therapy, identifying breast cancer as early as possible is critical for improving health outcomes. Breast health education organizations recommend that all women begin practicing BSE regularly as soon as their breasts are completely formed. For example, the Maurer Foundation recommends that BSE be conducted at least once a month beginning at the age of 18 years. Women get familiar with their breasts as a result of such regular scrutiny and are thus more likely to identify any changes [13].

Globally, the ratio of breast cancer cases is increasing day by day and it is the second leading cause of mortality [11]. In 2020, the women diagnosed with breast cancer was 2.3 million and the associated deaths were 685,000. Breast cancer is the world’s most prevalent cancer, as there were 7.8 million women alive who were diagnosed with breast cancer at the end of 2020 [12]. As compared to other cancer, there are more disability-adjusted life years (DALYs) lost by women to breast cancer globally [13]. In Pakistan, the number of reported breast cancer cases was 25, 928 which accounted for 14.5% of all types of cancer in 2020 [14]. The risk of developing breast cancer has risen in Pakistan, with one in every nine women having a lifetime risk of being diagnosed with this cancer [15].

Awareness about the disease play important role in its early diagnosis. This awareness helps the population to avoid risk factors associated with the disease. A heightened awareness of breast cancer disease can aid the women in adherence to its screening guidelines. This adherence will lead the population to the early diagnosis of breast cancer that will help the healthcare provider for better management and also will increase the surveillance rate of the patients. The university female students were less touched in the previous reports from Pakistan, and they were limited to a single location and specific domain like some were focused on risk factors other were sign and symptoms and breast cancer examination [16-19]. Therefore, the current national survey of Pakistan was conducted to assess the understandings and awareness of female university students about breast cancer’s risk factors, signs and symptoms, and breast cancer examination.

Material and method

Study design and participants

A cross-sectional approach was used in the current study. The study participants were university female students that were enrolled in the different universities of Pakistan. The students that were Pakistani nationals, had ages greater than 18 years, and who gave their consent to participate were included in the study. The term undergraduate includes bachelor programs (BS), while the post-graduate includes master (MPhil/MS), and doctorate programs (Ph.D.) in the current study.

Study instrument

A self-administered questionnaire was developed based on previous reports [20-22]. The questionnaire was composed of two parts. The first part comprised of demographic questions including age, education level, and residence area and province. While the second part comprised of questions regarding breast cancer risk factors, signs and symptoms, and the best time for breast examination. The domain which includes the risk factors were further divided into three sub-domains based on suggestions from the face validation and pilot study. The first sub-domain includes risk factors related to the history of breast cancer and benign diseases, exposure to radiation and use of medication (D1), the second sub-domain comprised of risk factors related to gynecology and obstetrics (D2), and the third sub-domain include the risk factors related to physical activities, and lifestyle (D3). The study instrument has been provided in the S1 File.

The questionnaire was validated through face validation followed by a pilot study (N = 75). The Cronbach’s alpha value of 0.81 was obtained, which indicated a good internal consistency.

Data collection

A total of 774 respondents have completed the survey that enrolled in different universities located in four provinces (Khyber Pakhtunkhwa, Punjab, Sindh, and Balochistan) of Pakistan through an online survey. Google forms (Google LLC, California, United States) were used to create the pre-tested questionnaire, and a link was shared with participants via social media platforms (Facebook, WhatsApp, and E-mail). An online written informed consent was taken from each participant before recruitment in the study. Participant confidentiality was maintained throughout the study. The hard file was kept in the department lab locker and the soft file was maintained in the password-protected folder. The online data was collected as per the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) guidelines [23, 24].

Ethical considerations

The current study was reviewed and approved by the Department of Pharmacy Practice, Faculty of Pharmacy, BZU Multan (Reference No: Acad/PRAC/21/04) and conducted as per the Declaration of Helsinki. The current study was reported according to “The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE)” guidelines [25].

Statistical analysis

The statistical package for social science (SPSS) (IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.) was used for data analysis. The descriptive statistics and cross-tabulation were performed and the frequency and percentage were calculated to illustrate categorical variables. The Chi-square test was applied to assess the association between study questions and education level. A p-value ≤ 0.05 was considered significant for all the statistical analysis. The Bonferroni correction was used to counteract with multiple comparisons.

Results

A total of 774 participants were participated in the study out of 852 and the response rate was 90.2% as shown in Fig 1. The mean (± standard deviation) age of the participants was 23.06 ± 4.35. The majority of the participants had single marital status (87.4%). Most of the respondents were belonging to pharmaceutical sciences (63.5%) followed by medical sciences (17.5%) and biological sciences (11.1%). Almost three-quarters of the participants were studying at the undergraduate level (74.9%) and most of the participants had rural residency (76.7%). Based on provincial distribution, the majority of the participant were belonging to Punjab (41.5%) followed by Khyber Pakhtunkhwa (28.3%) Sindh (17.1%), and Balochistan (13.1%) The detail of demographic characteristics can be seen in Table 1.

Regarding the breast cancer risk factors, most of the participants were unaware of the risk factors associated with breast cancer. only a small portion of the respondents was known to risk factors of breast cancer like the history of breast cancer in their first-degree relatives (29.8%) and benign breast disease (28%), use of oral contraceptives more than 5 years (14.1%), and after menopause use of hormone therapies (19.5%). More than one-quarter of the participants considered radiation as a risk factor for breast cancer (27.9%). Furthermore, risk factors such as a history of breast cancer (p = 0.005), benign breast illnesses (p = 0.008), hormone therapy after menopause (p = 0.009), and radiation at a younger age (p = 0.038) were found to differ significantly across educational levels. The undergraduate females were more knowledgeable about risk factors of breast cancer including the history of breast cancer in their relatives (UG: 76.2% vs PG: 23.8%) and benign diseases (UG: 79.7% vs PG: 20.3%), use hormone therapy (UG: 72.2% vs PG: 27.8%), and high exposure to radiations (UG: 76.9% vs PG: 23.1%) as shown in Table 2.

*The P-value represents the difference in the level of knowledge about risk factors of breast cancer between undergraduate and postgraduate students.

A poor knowledge about breast cancer’s risk factors was reported by the participants. As a small number of participants considered overweight and obesity (34.9%), lack of breastfeeding (28.3%), and low consumption of vegetables and fruits (43.5%) as the risks to breast cancer. Stress (UG: 74.4% vs PG: 25.6%, p = 0.020), high intake of red meat (UG: 71% vs PG: 29%, p = 0.035) and fatty food (UG: 75.6% vs PG: 24.4%, p = 0.008) were highly considered as risk factors for breast cancer by female undergraduate students.

Discussion

The current study was conducted to assess the knowledge and understandings of university female students about breast cancer. The participants reported overall poor knowledge regarding breast cancer risk factors, and signs and symptoms. Additionally, the knowledge was also poor regarding the best time for examination of breast cancer.

A good knowledge of risk factors can help in the prevention of breast cancer in the female population [26]. The history of breast cancer, in first-degree relatives, is the major risk factor for breast cancer [26]. In the current study, only 29.4% of the participants considered this as a risk factor for developing breast cancer. But in contrast, a good knowledge was reported from the female university students of Nigeria (46.4%) [27] and Uganda (48.5%) [28]. Moreover, studies published from Turkey (54.8%) [29] and China (63.6%) [30] reported a good knowledge regarding the development of breast cancer in females having a family history of this cancer. It has been reported that prolonged use of oral contraceptives (more than 5 years) increases the risk of developing breast cancer [26]. In Pakistan, majority of the population including female students don’t use contraceptive techniques and these methods are not discussed in-home and at universities. The current study results showed that only 14% of the participants marked the prolonged use of oral contraceptives as a risk factor for breast cancer. But in contrast, a study reported from Nepal showed moderate knowledge regarding the prior stated risk factor (35.7%) [31]. Moreover, only 19.1% of the participant favored early menstruation as a risk factor for breast cancer in the current study. This result was consistent with a reported study reported from Nepal, where 19.2% of the female students considered early menstruation as a risk factor for breast cancer [31]. It has been well established that breast cancer mostly develops in the older age population [3]. This risk factor was only recognized by 22% of the participants in the current study. This number was consistent with the previously reported study of Uganda university female students (25%) [28].

The early detection of breast cancer in females can only be possible when they are familiar with their signs and symptoms. In the current study, participants were little known to the signs and symptoms of breast cancer that include painless and palpable breast lump (38.6%), and painless mass under the armpit (35.5%). A comparatively higher knowledge about these signs and symptoms was reported from Ethiopia (53.7%, 57% respectively) [32] and in a similar study, painless breast lamp was correctly identified as breast cancer symptom by western Nepali higher secondary students [31], that was relatively higher as compared to our findings. Moreover, the participant in the current study was little known to the morphological changes in the breast like abrupt changes in size and shaped can be a sign and symptom of breast cancer while the awareness about this sign and symptoms was high in Sharjah (74.7%) and Ethiopian (74.3%) university female students [32, 33]. In the current study, the participant had poor knowledge regarding the signs and symptoms like wound around the nipple (25.7%) and bleeding or discharge from the nipple (28.4%). These findings were consistent with a reported study from China (37.2%, 29.4% respectively) [34].

The knowledge of screening tests for breast cancer has a vital importance in the early detection of cancer. The United States Preventive Services Task Force has recommended that women with an age range of 20–30 years should perform clinical breast examination by a healthcare provider every three years while women having age greater than 40 years should perform every year. The current study result was comparable with the recommendation as most of the participants suggested that clinical breast examination by a healthcare provider should be started after the age of 20 years (55.6%). While this frequency was low as compared to the study reported from nurses in the United Arab Emirates (96.1%). The difference in knowledge may be due to the study participants, as the study respondents were nurses which may have greater clinical experience.

The social norms of the Pakistani population have a significant effect on the participant’s knowledge. For instance, it has been reported that Pakistan women feel shyness, personal modesty, and embarrassment during the examination of breasts, especially in rural regions. The open discussion of issues, related to the breast, between women, mothers, daughters, and spouses or the extended family system is considered as a social taboo. This means that breast cancer is a socially unacceptable disease. Moreover, socioeconomic and cultural factors, such as age, employment status, lack of information, fear of surgery, trust in traditional therapies, and spiritual healing, lead the women in Pakistan to seek health facilities only at the end stages of breast cancer. Therefore, these factors are considered as a major barrier to breast cancer screening. That’s why they are diagnosed at the last stage when there is the only option of surgery [35-38]. Similarly in Iran embarrassment, fear of breast cancer diagnosis, and belief in fate were the major reported barriers by females to breast cancer screening [39]. In addition, the study conducted in Canada reported the uncomfortable feeling of women while discussing breast cancer screening as a barrier to the screening of breast cancer. The barriers to breast cancer screening, which include feeling uncomfortable while discussing screening. Pakistan is a middle-income country and 24.1% of the population lives below the national poverty line [40]. In addition, there is no program offered by the government for breast cancer education and screening [41]. Therefore, the population is unable to perform self-service screening practices of breast cancer, which also increases the risk of late diagnosis.

Study limitation

This study was subjected to various limitations. Firstly, the study was based on the questionnaire, therefore recall biases cannot be ignored. Secondly, the study population was university female students, however, the responses may be different from the illiterate population that was not included in the current study. Thirdly, as the majority of the participants are from the biological and medical backgrounds, therefore, response bias cannot be completely neglected. Lastly, the current study utilized online data collection, where responses from the population having no access to the internet were not collected.

Conclusion and recommendations

In summary, university female students reported a poor knowledge about breast cancer’s risk factors, signs and symptoms, and breast examination. Interestingly, although most of the participants were from pharmaceutical and medical sciences, still the knowledge was poor. It has been seen that good knowledge about breast cancer’s risk factors, signs and symptoms, and self, and clinical examination practices play an important role in the early detection of this cancer. The early diagnosis increases the chance of recovery and also improves the surveillance rate of breast cancer patients. In contrast, the current study showed poor knowledge about breast cancer that increases the risk of a diagnosis of this cancer at later stages. The late diagnosis negatively impacts the recovery and surveillance of breast cancer patients and also increases the burden on the healthcare system. Therefore, the government health administration and other related bodies (national and international) should play a role in awareness of the general public by arranging seminars. Moreover, it is suggested that awareness weeks in the educational sectors should be included in their policies. In addition, the breast cancer examination techniques should be included in their course content. Moreover, the government should encourage the health professional to spread the awareness among general population and the health facilities should be accessible to the population living in the countryside.
