Abstract

Background: Breast cancer (BC) has a major impact on women's health worldwide. The Kingdom of Saudi Arabia is no exception, where it is considered the most common malignancy, embodying the second leading cause of cancer deaths after lung cancer. In today's world, people are more health conscious and more aware of different medical specialties. Despite the tremendous advancements in education, there seems to be a limited knowledge among the public regarding this issue. Objective: The present study aims to assess the breast cancer awareness and its screening measurements among the common population. This study also evaluates the knowledge about Breast Self-Examination (BSE) and their opinion about its effectiveness in early diagnosis of breast cancer to detect the relationship between awareness and socioeconomic status. Methodology: This study is a cross-sectional prospective study with a sample of 202 female participants evaluated by questionnaire given to female attending lecture about breast cancer awareness in October 2018 in Jeddah, Saudi Arabia. The selection of participants was based on the simple random sampling method. Results and conclusion: The present study showed little awareness of BSE, mammography screening and clinical breast examination. However, breast cancer awareness was found to be quite optimal suggesting increasing knowledge of breast cancer awareness among Saudi females.

Introduction

Breast cancer (BC) is a common problem worldwide and is one of the major cause of death in females [1,2]. It is a type of cancer that originates in the breast tissue ranging from noninvasive to metastatic carcinoma. According to the International Agency for Research on Cancer, approximately, 2.1 million breast cancer cases were diagnosed in females worldwide in the year 2018 [3]. Breast cancer cannot be prevented, however its risk can be reduced and can be treated if detected at an early stage [4,5].

Evidence suggests that various factors are linked with the delay in seeking care and establishment of early diagnosis thereby making the treatment less effective. These factors include lack of public awareness about breast cancer symptoms, its mechanism of prevention, risk factors and treatment options [6,7].

One of the most essential factors that determines prognosis is early diagnosis of breast cancer. This increases the treatment efficacy and survival rate of breast cancer patients. Various methods like breast ultrasound, mammograms, clinical examinations and breast self-examination (BSE) has been suggested to help with early diagnosis. Screening of breast cancer is quite effective technique to decrease the morbidity and mortality associated with breast cancer. Various screening approaches such as clinical breast examination, self-breast examination and mammography are suggested to be beneficial in early screening and early detection of breast cancer and in improving women’s health [8].

Cancer-screening tests have greatly shown to decrease mortality in breast cancer patients [9]. According to the American Cancer Society (ACS), clinical breast examination (CBE) and mammography has been suggested for the early diagnosis of breast cancer [10]. Due to lack of knowledge and awareness of breast cancer in the society, many women fail to early diagnosis and treatment opportunities thereby conquering advanced stages of this disease [11].

Breast self-examination (BSE) is a practice of monthly palpation continually to a rigorous set method carried out by the female at the same time of each month [12]. In combination with improved breast awareness, BSE allows women to increase their perception of vulnerability to the risk of breast cancer [13]. This encourages them to participate in effective screening procedures which enable early breast cancer diagnosis and subsequent decrease in mortality.

Thus, it is essential to evaluate the existing knowledge and procedures linked with breast cancer and its screening in the common population. This will enable one to carry out effective health promotion strategies for decreasing breast cancer mortality that arises from improper health related activities and poor screening. The aim of the present study was to assess the public awareness about breast cancer, screening and breast self-examination among females in Jeddah, Saudi Arabia.

Patients and Methods

This study is a cross-sectional prospective study performed by distributing validated questionnaire to evaluate the female participant’s knowledge about the public awareness of breast cancer. A total 202 female participants were evaluated about the awareness using multiple questions related to the sample knowledge of the risk factors of breast cancer, breast selfexamination and other questions. The selection of participants was founded on the simple random sampling method.

93.6% of the sample who answered this question didn’t have any benign or malignant tumor compared to 6.4% who had a benign or malignant tumor (Figure 8).

Sample distribution by family history of breast cancer patients show that 13% of the sample who answered the question have one or more in their families who had breast cancer, compared to 87% who didn’t have any member of their family that have a breast cancer. And for those who have a member of their family that have a breast cancer having one patient on average, while the maximum patients in the same family is 4 and the minimum is 1 and 13.6% of the them was their Grandma, 22.7% is the daughter of their mother's aunt and 18.2% is their direct aunt from the father side.

Discussion

With the increasing incidence of breast cancer globally, and with many recent efforts to increase breast cancer awareness in Saudi Arabia, it is necessary to assess the existing knowledge and training of breast self-examination among Saudi females. Breast cancer awareness aims to inculcate and spread the knowledge of breast cancer in females, and stresses on the significance of breast self-examination. This would result in early diagnosis, and is more likely to decrease the incidence of breast cancer mortality. Awareness of breast cancer and breast self-examination is known to improve the health of females due to early reporting of symptoms, breast cancer screening thereby increasing the survival rate. Lack of breast cancer awareness is associated with late reporting of symptoms and hence higher mortality [14,15].

According to the present study, breast cancer awareness and BSE was found to suboptimal among Saudi females. This is in accordance with previous studies [16-18]. With respect to the risk of breast cancer, only a few of them answered that they smoke and less than quarter of them were previously exposed to radiation.

Among the various types of screening methods, BSE is the best way and is the most cost-effective procedure, if women have adequate knowledge. BSE is an effective tool for the detection of breast cancer at an initial stage [19,20]. It was reported that most females can detect breast cancer by breast selfexamination, thereby having a better diagnosis and treatment [21]. Many studies have shown that most women do not have much knowledge about BSE and some of them who have knowledge about this method do not carry out it regularly [22-24]. According to the present study, less than half of the participants performed breast self-examination and few of them check periodically. Mammography screening is another screening tool for breast cancer diagnosis. It has been suggested that screening by mammography can decrease the breast cancer mortality 25% in females aged over 50 years [25]. Breast ultrasound is relatively and common method for breast cancer screening. It is an optimal method while assessing women aged under 40 years [26]. In the present study, it was found that only a quarter of the participants were examined by the doctor for breast cancer and only few of them underwent mammogram screening and breast ultrasound which was quite low. This is in accordance with the previous study of Dandash et al. [27].

In contrast, breast cancer awareness among the population was found to be quite significant. 88% believed that taking a sample of the breast does not lead to the spread of the tumor and a very few of them answers that breast cancer is contagious. Most of them knew that breast feeding prevents breast cancer. The present study showed quite a good response of breast cancer awareness as reported by the earlier study conducted in Jeddah, Saudi Arabia [28].

Conclusion

In conclusion, the present study showed little awareness of BSE, mammographic screening and clinical breast examination. However, in terms of breast cancer awareness, the results were quite good suggesting increasing knowledge of breast cancer awareness among Saudi females. As only a few females did mammogram screening and breast ultrasound, several measures need to be taken in order to increase awareness on BSE among the population.
