  • Background: This study analyzed predictors of regular mammography performance in Korea. In addition, we determined factors affecting regular mammography performance in life-transition aged women by applying an attitude, social influence, and self-efficacy (ASE) model. Materials and Methods: Data were collected from women aged over 40 years residing in province J in Korea. The 178 enrolled subjects provided informed voluntary consent prior to completing a structural questionnaire. Results: The overall regular mammography performance rate of the subjects was 41.6%. Older age, city residency, high income and part-time job were associated with a high regular mammography performance. Among women who had undergone more breast self-examinations (BSE) or more doctors' physical examinations (PE), there were higher regular mammography performance rates. All three ASE model factors were significantly associated with regular mammography performance. Women with a high level of positive ASE values had a significantly high regular mammography performance rate. Within the ASE model, self-efficacy and social influence were particularly important. Logistic regression analysis explained 34.7% of regular mammography performance and PE experience (${\beta}=4.645$, p=.003), part-time job (${\beta}=4.010$, p=.050), self-efficacy (${\beta}=1.820$, p=.026) and social influence (${\beta}=1.509$, p=.038) were significant factors. Conclusions: Promotional strategies that could improve self-efficacy, reinforce social influence and reduce geographical, time and financial barriers are needed to increase the regular mammography performance rate in life-transition aged.

  • 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.

  • Objective: This research was conducted to determine the breast cancer risk levels of women with and without previous mammography and their beliefs on breast cancer and mammography. Methods: The sample for this descriptive research consisted of women aged 50 years or older who were registered at the Family Health Center in the city center of Erzurum. The research was conducted with a total of 420 women with at least one mammography (210) and without mammography (210) who presented to the center on Wednesdays and Thursdays for any reason between 1 January 2010 and 1 January 2011. Research data were collected using the personal information "Breast Cancer Risk Assessment Form" accepted and recommended by the Turkish Ministry of Health, and the Champion's Health Belief Model Scale for Breast Cancer and Screening (CHBMS). Data were evaluated using percentages and means with the t-test. Results: According to the research data, 89.8% of the women were found to be in the low risk group, 87.6% with and 91.9% without mammography. When the health beliefs of women with and without mammography were compared, it was found that susceptibility, seriouness, motivation, mammography benefit scores were higher among those with mammography (p<0.01). The mammography barrier score average was higher in the group without mammography (p<0.01). Conclusion: Knowing women's health beliefs, which have positive and negative effects on participating in mammography screening, may increase the rate of mammography uptake among women. Moreover, women with high breast cancer risk may be determined by increasing society's level of knowledge on breast cancer and risk factors.

  • Mammography is considered the single most important diagnostic tool in the early detection of breast cancer. Today's dedicated mammographic equipment, specially designed x-ray screen/film combinations, coupled with controlled film processing, produces excellent image quality and can detect very low contrast small lesions. In mammography, it is most important to produce consistent high-contrast, high-resolution images at the lowest radiation dose consistent with high image quality. Some of the major technical development milestones that have let to today's high quality in mammographic imaging are reviewed. Both the American College of Radiology Mammography Accreditation Program and the Mammography Quality Standards Act have significant impact on the improvement of the technical quality of mammographic images in the United States and worldwide. A most recent development in digital mammography has opened up avenues for improving diagnosis.

  • Mammography using mammography equipment is a method of examination that is being employed most widely to diagnose the early stages of breast cancer. Detecting or diagnosing a fibrous tissue, micro calcification, or mass in the breast is influenced by the quality management of mammography equipment considerably. Particularly in mammography, quality management refers to a behavior of figuring out and correcting all sorts of hindrance factors that can cause all the problems related to the equipment associated with the diminishment of diagnosed area due to the reduction of image quality in clinical imaging in advance and maintaining a consistent level of image quality and obtaining a proper image. Here, these researchers aim to summarize and report the general contents of quality management in mammography using mammography equipment.

  • This study was carried out to assess the perception of decisional balance of Korean women toward mammography screening. From Dec. 20, 1998 to Apr. 30, 1999, a samples of 1,903 subjects were selected from 7 metropolitan areas and 6 provinces of Korea. Data was collected using Rakowski et al's decisional balance scale to measure the decisional balance regarding a woman's adoption of mammography screening and to assess the woman's current stages of adoption of mammography. The classification of women according to the stage of adoption of mammography was 54.9 % in precontemplation, 31.9 % in contemplation, 7.8 % in action, and 5.5 % in maintenance. The mean difference of pros, cons, and the decisional balance by the stage of mammography adoption were statistically significant. There were significant mean differences between the stages of adoption according to a woman's experience with and intention for mammography and the pros score, the cons score, and the decisional balance score. The behavioral portion of stage of mammography adoption provides a further level of discrimination. Results provide the empirical evidence for the Transtheoretical model.

  • Background: Despite the efficacy of regular mammograms, the incidence and mortality rate of breast cancer have been increasing in China. Insufficient studies on the factors affecting mammography adherence in Chinese married women have been conducted. The purpose of the present study was to explore the factors associated with adherence to guidelines for regular mammography among Chinese married women. Materials and Methods: The participants were recruited conveniently and included Chinese and Korean Chinese women who were married, living at Yanbian City in China. Demographic information, status regarding eight risk factors of breast cancer, health responsibility, and perceived benefits/barriers of mammography were obtained. Descriptive analyses, t-test, and multivariate analysis were performed. Hierarchical logistic regression was conducted to explore the factors associated with regular mammography adherence in Chinese and Korean Chinese subgroups. Results: About 24% of the sample population was adherent in going for regular mammography. The adherent group was significantly more educated, had more children, and had a lower proportion experiencing early menarche and a greater menopausal proportion than the non-adherent group. The final model using logistic regression analysis showed that being Chinese [OR=2.199 (1.224-3.951)], having no or one child [OR=4.879 (1.835-12.976)], early menarche [OR=3.515 (1.057-11.694)], being menopausal [OR=3.120 (0.965-10.088)], aged 40-49 [OR=2.374 (1.099-5.124)], having low education [OR=0.400 (0.211-0.765)], and perceiving greater benefits in doing mammography [OR=1.080 (1.014-1.151)] were significantly associated with mammography adherence, after controlling for covariates. Conclusions: Sociocultural sensitive intervention for minorities should be emphasized when improving the adherence of regular mammography. Intervention tailored for women with lower education should be delivered and the benefits of mammography should be propagated to women in rural areas of China.

  • Purpose: The purpose of this study was to examine factors related to different stages of mammography screening based on the transtheoretical model (TTM) and health belief model (HBM). Method: 143 women were recruited from community centers in W city. The mean age was 44.08 (SD=7.78) and 74 (51.7%) had experienced education on preventative behavior related to breast cancer. The Decisional Balance Scale (Pros and Cons of mammography) and Stages of Adoption of Mammography Scale by Rakowski et al. (1992) and the revised Health Belief Model Scale (Perceived Seriousness, Perceived Susceptibility and Health Motivation) by Champion (1993) were used. Result: According to the stage of adoption of mammography, 17.4% of the women were In pre-contemplation, 45.5% in contemplation, 24.5% in action, and 12.6% in maintenance. The mean differences for pros, and the decisional balances between the stages of mammography adoption were significant (F=8.84, p=.000; F=7.20, p=.000). Education related to prevention of breast cancer was the most important variable. Prevention education, history of breast disease and pros of mammography explained the stages of mammography adoption ($R^{2}=26%$). Conclusion: Findings support TTM as a useful tool for improving mammography adherence. Behavioral interventions that target decisional balance and health belief can effectively promote adherence to mammography.

  • Background: Mammography is considered the gold standard of breast cancer mass screening and many countries have implemented this as an established breast cancer screening strategy. However, although the incidence of breast cancer and racial characteristics are different between Western and Asian countries, many Asian countries adopted mammography for mass screening. Therefore, the objective of this research was to determine whether mammography mass screening is cost-effective for both Western and Asian countries. Materials and Methods: A systematic review was performed of 17 national mammography cost-effectiveness data sets. Per capita gross domestic product (GDP), breast cancer incidence rate, and the most optimal cost-effectiveness results [cost per life year saved (LYS)] of a mammography screening strategy for each data set were extracted. The CE/per capita GDP ratio is used to compare the cost-effectiveness of mammography by countries. Non-parametric regression was used to find a cut-off point which indicated the breast cancer incidence rate boundary line determining whether mammography screening is cost-effective or not. Results: We found that the cost-effective cut-off point of breast cancer incidence rate was 45.04; it exactly divided countries into Western and Asian countries (p<0.0014). Conclusions: Mammography screening is cost-effective in most of Western countries, but not in Asian countries. The reason for this result may be the issues of incidence rate or racial characteristics, such as dense breast tissue. The results indicate that mammography screening should be adopted prudently in Asian countries and other countries with low incidence rates.

  • Since the mean age of breast cancer in women living in developing countries, compared with those in developed countries, is lower by about 10 years, repetition of mammography can play an important role in reducing morbidity and mortality. Hence, this study aimed to investigate the relationship between family history of breast cancer and risk perception and its impact on repetition of mammography. In this cross-sectional study, 1,507 women aged 50 years and older, referred to the mammography center of Regions 1 and 6 in Tehran, Iran, were enrolled. Data were collected using a self-report questionnaire and analyzed using SPSS and LISREL. According to our findings, knowledge about the time interval of mammography was found to have the highest correlation with repetition of mammography (r=0.4). Among the demographic variables, marital status (${\beta}$= -0.1) and family history of breast cancer (${\beta}$=0.1) had the most direct and significant impact on repetition of mammography (P <0.05). Among the other variables studied, knowledge (${\beta}$=-0.5) had the highest direct and significant impact on repetition of mammography (P <0.05). Family history of breast cancer was one of the predictors of repetition of mammography, but the results did not prove any relationship with risk perception. Further studies are needed to assess the effect of risk perception and knowledge about time interval on the initiation and continuation of mammography.
