Are Women who consider BSE effective in detecting breast cancer more likely to be aware of BSE, or vice versa? The present study was an attempt to answer this question. Methods: A cross-sectional study was performed for 259 female University students in Kampala, Uganda. Data were analyzed using SPSS. Univariate and bivariate analyses were carried out. Results: The majority (64.1%) were aware of the BSE technique. Women considering BSE to be effective for early cancer detection were significantly more likely to be aware of the BSE technique. Conclusions: University students who believed in the benefits of BSE were more likely to be aware of BSE than those who did not. More emphasis should be placed on health education for women of younger ages to increase the knowledge of the practice of BSE.展开更多

With an estimated incidence of 1,676,633 with 521,817 deaths in the year 2012, the figure is expected to hit the 82.5 millionth mark by 2015. Breast cancer screening is reported to be extremely low in most low-middle income countries like Ghana. This study was to determine the knowledge and practices of self-breast examination among market women at Makola Shopping Mall in Accra, Ghana. Methods: The study was conducted at the Makola Shopping Mall in Accra among women above the age of 20 years who owned a store and sell at the mall. Data were collected using mixed method involving in-depth interviews and questionnaire survey. Random samples of 170 participants were selected from a population of 400 for the quantitative survey. A total of eight in-depth interviews were conducted to generate qualitative data to complement the survey data. Results: Majority (60%) of the respondents were between the ages of 20 - 40 years. There’s a high literacy rate among the participants. Though awareness of self-breast examination was very high (93%), only 27% practiced self-breast examination in line with the recommended one week period after menses due to lack of knowledge of the basic skills to do self-breast examination. Conclusion: In view of the lack of knowledge resulting in non-performance of self-breast examination, continuous education on breast cancer screening should be given to the women to enable them acquire the skills of performing self-breast examination to promote early detection of the disease.展开更多

It is the most common cancer in women and is equally the leading cause of cancer death in women. Though in controversy Breast self-examination (BSE) remains a useful tool in early diagnosis of breast cancer. The aim of this study was to evaluate the knowledge, attitude and practice of BSE amongst women in Yaoundé and Monatele. We carried out a cross sectional study in two communities of Cameron over a period of eight months, targeting females older than 15 years. After obtaining authorization, we randomly interviewed 402 consenting participants, using a pretested questionnaire. Data were entered using CS Pro 7.3 and analysed using SPSS 23. Of a total of 402 participants, 256 (63.7%) in Monatele and 146 (36.3%) in Yaoundé VI, the mean age was 26.55 ± 9.57 years. Exactly 50% (201) had earlier heard of BSE. Health personnel and media represented the main sources of information on BSE. Of the total, 46 (11.4%) knew BSE should be done monthly. Fifty-three percent had poor knowledge and 51.0% had a generally low attitude towards BSE. Out of 402 participants, 65.2% reported not practicing BSE. For those practicing, 71.6% had poor practices. The main reason for not practicing was lack of knowledge. Poor knowledge increased poor practice. In conclusion half of the women had heard about BSE even though the majority had a poor knowledge on BSE and very low overall attitude and practice. Health personnel and media played a key role in passing of information. Increasing the number of health campaigns, multiplying TV shows and health talks about breast self-examination will improve knowledge and hence attitude and practice.展开更多

Despite the availability of early detection methods to diagnose breast cancer, a huge number of women are still unaware about these methods. This study was conducted to identify the attitude of women in Medina toward breast cancer screening methods, including breast self-examination (BSE), clinical breast examination (CBE) and mammography. Methods and Materials: A cross-sectional survey has been conducted on 124 women aged from 39 and older, who attended Taibah Medical Center for cancer screening either by doctor’s recommendation, family or friends advice, or by herself. Face to face questionnaire was used to collect data. All data were analyzed by statistical analysis system software. Results: The results showed only 35.5%, 27.4% and 37.8% of participants reported that they practiced BSE, CBE and annual mammography, respectively. Only 27.3% of women practiced BSE once per month, and 8.8% visited doctor annually for CBE. Both educational level (p = 0.004) and family history (p = 0.01) were significantly related to BSE. 57.7% of the participants who had positive family history practiced BSE, and 56.0% of the participants who practiced BSE were highly educated. Lacking awareness about BSE is the most important barrier in not practicing BSE, while not having a breast lump was the reason for not undergoing either clinical breast examination (38.7%) or periodic mammography (54.9%). Conclusion: This study emphasized the need for massive health education program to increase awareness, and improve the attitude of women toward breast cancer screening methods.展开更多

A descriptive survey design was adopted. The study population of 349 was drawn using system atichousehold sampling technique. Two research questions and three null hypotheses guided the study. The instruments used for data collection were validated structured questionnaire which was interview administered. Demographic information of the women such was also obtained for the study. The result indicated significant correlation between respondents’ educational level and BSE. There was however no significance difference between age, parity and BSE. There was need for community health nurses to reinforce home visits in order to enhance the awareness of breast cancer and needed skill for BSE among the rural populace while liberal education irrespective of age should be instituted by the Government.展开更多

Breast Self-Examination (BSE) is the quickest and cheapest means of early breast cancer detection. The objective of this study was to determine the knowledge and practice of breast self-examination among female undergraduates in Owerri, south eastern Nigeria. A multi-stage sampling design was used to select participants. Interview using structured questionnaire was conducted on randomly selected respondents in six faculties from each tertiary institution. Questionnaire was prepared in English and was self-administered. Permission to conduct the survey was requested and obtained from the university ethical review board. Informed verbal and written consent was obtained from participants. Confidentiality of information was maintained throughout the study. Knowledge and practice of BSE was examined among 720 randomly selected female undergraduates aged 16 to 28 years. It was found that 98.9 percent have heard of BSE but only 32.5 percent of them performed this examination accurately and monthly as required. There is a statistically significant relationship between knowledge of risk factors for breast cancer and practice of BSE (χ2 = 31.17, P χ2 = 86.75, P χ2 = 75.94, P < 0.001). These female undergraduates had a poor knowledge of the right procedure and practice of BSE;therefore there is need for awareness creation on the risks of breast cancer and benefits of early detection among female undergraduates through breast self-examination.展开更多

This study employed a descriptive design and data was collected with the aid of validated semi structured questionnaire from 100 female teachers in all the five secondary schools in Oko, Oyo State, and analysis was done using Statistical Package for Social Sciences. The result showed that 82% of the respondents were aware of breast self examination practices and their source of this information was from mass media (55%) and friends (25%). Fifty-four respondents had poor knowledge of BSE and 48% had negative attitude towards practice of BSE and majority (62%) had a low practice. The study however, revealed that majority of the respondents who practice BSE do not know what to look for. The results further showed that, there is no significant relationship between age of the respondents and their awareness (X2 = 8.322;p = 0.0800;df = 4) and knowledge (X2 = 14.501;p = 0.264 and df = 8) of breast self examination. This study concluded that there is poor knowledge and attitude towards BSE practice among the secondary school teachers in Oko community and with unsatisfactory practice. It therefore, suggests that breast awareness campaign and self efficacy development is important for teachers in secondary schools to aid early detection and better prognosis of breast cancer in this community, and this will have a multiplier effect on female secondary school girls.展开更多

Different studies conducted in the Kingdom have shown that knowledge of females regarding breast cancer is poor. Aim of the study was to determine knowledge, attitude and practice among students of Saudi female medical university towards Breast Self Examination (BSE) and also to explore their knowledge about breast cancer. Research Methodology: An observational cross-sectional study was conducted at Faculty of Medicine, Taif University during October 2013. Sample size was 378 with mean age of 19.9 ± 1.5. A self administrated questionnaire was used to obtain data about knowledge, attitude and practice towards BSE and knowledge about breast cancer. Data were collected and fed to SPSS version 16. Shape of distribution for numerical data was tested by using one sample Kolmogorov-Smirnov test. Chi-Square Test & Fissure Exact Test (FET) were used for testing relation between categorical variables while correlation analysis was used to test the strength of relation between numeric variables. Main Results: The study revealed that only 8.2% of participants had good overall knowledge about breast cancer and BSE. Although 66% of the study sample had positive attitude towards BSE, only 17% reported that they practiced BSE monthly. A significant positive moderate correlation was found between overall knowledge score and attitude towards BSE (r = 0.449 & p = 0.000). The same was for the frequency of BSE practice but it was found to be in a weak magnitude (r = 0.223 & p = 0.000). Conclusion and Recommendations: Although there was lack of knowledge about breast cancer and BSE yet, positive attitude towards BSE was encouraging. Most female medical students in our sample did not perform BSE or perform it irregularly. Therefore, more intensified awareness programs among students of medical university are necessary to keep in view their current status of breast cancer and BSE knowledge. Further researches are needed to identify causes of inadequate knowledge and practice of BSE among medical students in Taif.展开更多

Breast self examination makes women more “breast aware”, which in turn may lead to an earlier diagnosis of breast cancer. In Nigeria, the statistics of breast cancer have overtaken cancer of the cervix to become the commonest malignancy in women. This study was carried out to determine the awareness of breast cancer risk factors and practice of breast self examination among female students of the University of Nigeria Enugu Campus. The descriptive survey design was used for the study. The population of the study was all the female students that reside in hostels in the campus (2400) in number. A sample of 240 students was selected using quota sampling technique. Structured questionnaires based on the research objectives were used for data collection. The results of the study showed that most of the students have little knowledge of breast cancer risk factors and majority of the students do not practice BSE monthly. It was recommended that there should be regular organization of seminars and workshops for students to address sensitive topics like breast cancer risk factors and breast self examination.展开更多

Methods: A descriptive, cross sectional study was conducted in the nursing department of a tertiary institution in Benin City, Edo state. The age range of the study population was between 17-31 years. Convenient sampling technique was used to select 200 female students. The instrument used was a structured questionnaire. The questionnaire was divided into 4 sections: i) Bio-data;ii) knowledge of self breast examination;iii) practice self breast examination;iv) factors affecting SBE. Results: The results of this study indicated that majority of the students were knowledgeable about self breast examination and majority of them practiced self breast examination. The alternate hypothesis which stated that there was a significant difference between factors affecting SBE was retained and the mean values revealed that “forgetfulness” as a factor had the highest mean value. This meant that “forgetfulness” was a potent factor to SBE among the respondents studied. Conclusion: The students in this tertiary institution were aware of self breast examination and they did practice it. Studies like these could enhance the knowledge regarding BSE among nurses and other health professionals.展开更多

The infrastructural performances reflect design and geometrical characteristics of the HSR lines and stations. The technical/technological performances relate to the characteristics of rolling stock, i.e., high-speed trains, and supportive facilities and equipment, i.e., the power supply, signaling, and traffic control and management system(s). The operational performances include the capacity and productivity of HSR lines and rolling stock, and quality of services. The economic per- formances refer to the HSR systems' costs, revenues, and their relationship. The social performances relate to the impacts of HSR systems on the society such as congestion, noise, and safety, and their externalities, and the effects in terms of contribution to the local and global/country social- economic development. Finally, the environmental performances of the HSR systems reflect their energy consumption and related emissions of green house gases, land use, and corresponding externalities.展开更多
