    Breast cancer mostly arises from the glandular (dense) region of the breast. Consequently, breast density has been found to be a strong indicator for breast cancer risk. Therefore, there is a need to develop a system which can segment or classify dense breast areas. In a dense breast, the sensitivity of mammography for the early detection of breast cancer is reduced. It is difficult to detect a mass in a breast that is dense. Therefore, a computerized method to separate the existence of a mass from the glandular tissues becomes an important task. Moreover, if the segmentation results provide more precise demarcation enabling the visualization of the breast anatomical regions, it could also assist in the detection of architectural distortion or asymmetry. This study attempts to segment the dense areas of the breast and the existence of a mass and to visualize other breast regions (skin-air interface, uncompressed fat, compressed fat, and glandular) in a system. The graph cuts (GC) segmentation technique is proposed. Multiselection of seed labels has been chosen to provide the hard constraint for segmentation of the different parts. The results are promising. A strong correlation (r = 0.93) was observed between the segmented dense breast areas detected and radiological ground truth.

    INTRODUCTION: This review aimed to summarise the trend of mammogram screening uptake published in local studies between years 2006 and 2015 among the Malaysian women aged 40 years and above, and identify the associated factors and barriers, as well as discuss limitations of the studies and research gaps.

    METHODS: A systematic review was conducted on breast cancer screening studies among Malaysian women, published between January 2006 and December 2015. Online databases were searched using keywords: "mammogram", "mammography", "uptake", "breast cancer screening" and "Malaysia".

    RESULTS: Thirteen original articles were reviewed. The rate of mammography uptake ranged between 3.6% and 30.9% among the general population, and 80.3% among personnel of a tertiary hospital. Factors associated with mammogram screening were clinical breast examination, age, income, knowledge on breast cancer and mammogram, perceived susceptibility to breast cancer, ethnicity and education level. Barriers to mammogram screening were lack of knowledge, embarrassment, fear of cancer diagnosis, perception that breast screening was unnecessary, lack of coping skills and pain during procedure. However, almost all of the studies could not be generalised beyond the study sample because of the limited number of sites and respondents; and most data were self-reported with no objective measures of the responses.

    CONCLUSION: Mammogram screening uptake among women in selected communities were generally low. Further studies involving the general population are essential. Future studies should also explore the availability, affordability and accessibility of this service especially in the pursuit of achieving universal health coverage in breast cancer management.

    BACKGROUND: The incidence of breast cancer in Asia is increasing because of urbanization and lifestyle changes. In the developing countries in Asia, women present at late stages, and mortality is high. Mammographic screening is the only evidence-based screening modality that reduces breast cancer mortality. To date, only opportunistic screening is offered in the majority of Asian countries because of the lack of justification and funding. Nevertheless, there have been few reports on the effectiveness of such programmes. In this study, we describe the cancer detection rate and challenges experienced in an opportunistic mammographic screening programme in Malaysia.

    METHODS: From October 2011 to June 2015, 1,778 asymptomatic women, aged 40-74 years, underwent subsidised mammographic screening. All patients had a clinical breast examination before mammographic screening, and women with mammographic abnormalities were referred to a surgeon. The cancer detection rate and variables associated with a recommendation for adjunct ultrasonography were determined.

    RESULTS: The mean age for screening was 50.8 years and seven cancers (0.39%) were detected. The detection rate was 0.64% in women aged 50 years and above, and 0.12% in women below 50 years old. Adjunct ultrasonography was recommended in 30.7% of women, and was significantly associated with age, menopausal status, mammographic density and radiologist's experience. The main reasons cited for recommendation of an adjunct ultrasound was dense breasts and mammographic abnormalities.

    DISCUSSION: The cancer detection rate is similar to population-based screening mammography programmes in high-income Asian countries. Unlike population-based screening programmes in Caucasian populations where the adjunct ultrasonography rate is 2-4%, we report that 3 out of 10 women attending screening mammography were recommended for adjunct ultrasonography. This could be because Asian women attending screening are likely premenopausal and hence have denser breasts. Radiologists who reported more than 360 mammograms were more confident in reporting a mammogram as normal without adjunct ultrasonography compared to those who reported less than 180 mammograms.

    CONCLUSION: Our subsidised opportunistic mammographic screening programme is able to provide equivalent cancer detection rates but the high recall for adjunct ultrasonography would make screening less cost-effective.

    Objective: This study aims to investigate the public pattern in seeking breast cancer screening information in
    Malaysia using Google Trends. Methods: The Google Trends database was evaluated for the relative Internet search
    popularity of breast cancer and screening-related search terms from 2007 to 2018. Results: Result showed downward
    trends in breast cancer search, whereas mammogram and tomosynthesis search fluctuated consistently. A significant
    increment was found during Pink October month. Breast cancer search term achieved the highest popularity in the east
    coast of Malaysia with [x2 (5, N=661) = 110.93, P<0.05], whereas mammogram attained the highest search volume in
    central Malaysia [x2 (4, N=67) = 18.90, P<0.05]. The cross-correlation for breast cancer was moderate among northern
    Malaysia, Sabah, and Sarawak (0.3 ≤ rs ≤ 0.7). Conclusion: Public interest trend in breast cancer screening is strongly
    correlated with the breast cancer awareness campaign, Pink October. Breast cancer screening should be promoted in
    the rural areas in Malaysia.

    BACKGROUND: Worldwide, over half a million women died of breast cancer in 2011 alone. Mammography screening is associated with a reduction of 20 to 35% in breast cancer mortality. The aim of this study was to determine the awareness and practice of mammography screening and predictors of its uptake in Malaysian women attending a primary care clinic.

    MATERIALS AND METHODS: A cross-sectional study was carried out among women aged 40 to 74 years attending a primary care clinic in Selangor, Malaysia. An assisted structured questionnaire included questions on socio-demography, source of information and level of knowledge. An adapted version of the revised Champion Health Belief Model Scale plus other associated factors for mammography screening up-take were also included as part of the questionnaire. Predictors for mammography screening uptake were only determined in those who were aware about mammography screening. Significant predictors were determined by logistic regression.

    RESULTS: 447 women were recruited for this study; 99.1% of them (n: 411) were aware about breast cancer. Only 50.1% (n: 206) had knowledge about mammography screening. Prevalence of clinical breast-examination (CBE) was 23.3% (n: 104) and mammography screening up-take was 13.2% (n: 59). The predictors for the latter were those who have had clinical breast-examination (aOR=17.58, 95%CI: 7.68-39.82) and those aged between 50 to 59 years (aOR=3.94, 95%CI: 1.61-9.66) as well as those aged 60 years and above (aOR=6.91, 95%CI: 2.28-20.94). Good knowledge and positive beliefs about mammography screening were not associated with mammography screening uptake.

    CONCLUSIONS: Half of our Malaysian women were aware about mammography screening. However, the uptake of mammography was low. Previous CBE and older age were significant predictors of mammography screening uptake. Increasing CBE services may increase compliance with guidelines.

    Breast cancer is the most common cancer among women globally. This study was conducted to compare the awareness of breast cancer and the practice of breast self-examination (BSE), clinical breast examination (CBE) and mammography screening among rural females in Pahang and Perak. A cross-sectional study was carried out in five selected rural districts of Pahang and Perak. Two hundred and fifty households were randomly selected and interviewed face to face using a semi-structured questionnaire. The majority of residents from both states were Malay, aged between 50 and 60 years and had a secondary level of education. Malay women aged 40-49 years and women with a higher level of education were significantly more aware of breast cancer (p<0.05). About half of these women practiced BSE (60.7%) and CBE (56.1%), and 7% had underwent mammography screening. The results of this study suggest that women in Pahang and Perak have good awareness of breast cancer and that more than half practice BSE and CBE. The women's level of education appears to contribute to their level of knowledge and health behaviour. However, more effort is needed to encourage all women in rural areas to acquire further knowledge on breast cancer.

    OBJECTIVE: The objective of this study was to determine the practice and barriers of mammography and associated factors among Malaysian women in the general population.

    METHODOLOGY: A cross-sectional study was conducted among 200 women in Shah Alam, Selangor; Malaysia. The questionnaire contained 27 questions and was comprised of two sections; socio-demographic characteristics and practices, knowledge and barriers of mammography. All the data were analyzed using the Statistical Package for the Social Sciences (SPSS) 13.0.

    RESULTS: Of the 200 Malaysian women who participated in this study, the majority were under the age of 50 years (65.5%), Malay (86%), and married (94.5%). Regarding any family history of cancer in general, the majority of the participants had none (78%). However, some did report a close relative with breast cancer (16.5%). While the majority of them knew about mammography (68%), 15% had had a mammogram once in their life and only 2% had the procedure every two or three years. Univariate analysis showed that age, family history of cancer, family history of breast cancer, regular supplement intake, regular medical check-up and knowledge about mammogram were significantly associated with mammogram practice among the general population (p=0.007, p=0.043, P=0.015, p=0.01, p=0.001, p<0.001; respectively). Multivariate analysis using multiple linear regression test showed that age, regular medical check-up and knowledge about mammography testing were statistically associated with the practice of mammography among the general population in Malaysia (p=0.035, p=0.015 and p<0.001; respectively). Lack of time, lack of knowledge, not knowing where to go for the test and a fear of the test result were the most important barriers (42.5%, 32%, 21%, 20%; respectively).

    CONCLUSION: The practice of mammogram screening is low among Malaysian women.

    Mammography utilization is low in Iran compared with other countries. Here a cross-sectional survey design was used to investigate psycho-social and individual factors associated with mammography among 400 women asymptomatic of breast cancer. The study was carried out at the four outpatient clinics of Tehran during the period from July through October, 2009. We found that mammography screening was related to higher self-efficacy and women's occupation. Future tailored interventions on potential psycho-social determinants and specific demographic factors are critical in increasing mammography screening rates among Iranian women.

    OBJECTIVE:
    This study investigated rural women's knowledge of breast cancer and screening methods by ethnicity and examined the predictors of breast screening methods.

    METHODS:
    A cross-sectional survey was conducted in 2011 in five rural districts of Perak; 959 women were interviewed using a semi-structured questionnaire. ANOVA and regression analysis were used in data analysis.

    RESULTS:
    Women below 50 years old, of Malay ethnicity and who had secondary education scored better than those older, of Chinese ethnicity and had primary education (p<0.001). The uptake of breast self-examination (BSE), clinical breast examination (CBE) and mammogram was 59%, 51% and 6.8%, respectively. Multivariate analysis revealed knowledge of breast cancer and CBE as top predictors of BSE, being married and knowledge of breast cancer as top predictors for CBE; and CBE as the top predictor of mammography uptake. Support from husbands and family members for breast cancer screening was a predictor for CBE and BSE.

    CONCLUSION:
    Knowledge of breast cancer and its screening uptake varies by ethnicity, location and the type of support received. Efforts and approaches to improve the women's knowledge of breast cancer and its screening uptake therefore should be customized to address the different influencing factors.

    Background: Breast cancer (BC) awareness is relatively poor among Malaysian women indicated by the presence of BC at a late stage and the low rate of mammography screening. Only a few theoretically based studies have been conducted on Malaysian women’s participation in mammography. Therefore, the objective of this study is to use health belief model (HBM) and stage of change model (SCM) to determine the relationship between health beliefs on the behavioral adoption of mammography amongst women in Kuantan, Pahang. Methods: Five hundred and twenty women were randomly selected to complete the survey. Data were analyzed using multinomial logistic regression (MLR) to ascertain the multivariate relationships between health beliefs and stage of mammography behavioral adoption. Results:
    The MLR test indicates that there is no significant difference in perceived severity, benefits, motivator factors and cues to action between participants in the action stage and the maintenance stage. However, significant differences existed in perceived severity, susceptibility, motivator factors and self-efficacy between the pre-contemplation, relapse and contemplation stage to that of the referenced (maintenance) stage of mammography adoption. Conclusion: Women in the action stage are more likely to progress towards maintenance stage as they perceived breast cancer as a disease that leads to death and that mammogram screening is beneficial in detecting the disease at an early stage. However, women in the pre-contemplation, relapse and contemplation stage are found unlikely to move towards the maintenance stage as they perceived their risk of getting breast cancer is low.

    BACKGROUND: Although significant consideration has been devoted to women participation in breast cancer prevention programs, our understanding about the psychosocial factors which influence participation remains incomplete.

    METHOD: The study applied a quantitative approach based on the cross-sectional survey design and multistage cluster random sampling. A total of 400 women aged 35-69 years, were surveyed at 4 obstetric and gynecologic clinics affiliated to Tehran University of Medical Sciences in Tehran: the participation levels of 86 women who have had a mammogram were analyzed based on their self-efficacy, belief, social influence, and barriers concerning mammography utilization.

    RESULTS: Consistent with the study framework, in bivariate analysis, the higher level of women's participation in breast cancer prevention programs was significantly related to more positive belief about mammography (p< .05), greater social influence on mammography (p< .01) and fewer barriers to mammography (p< .01). Self efficacy (p= .114) was not significantly related to the higher level of participation.

    CONCLUSION: Results suggest that women's participation levels in breast cancer prevention programs might be associated with the specific psychosocial factors on breast cancer preventive behavior such as mammography screening.
