Breast cancer is a leading cause of mortality among women in the United States. Women with chronic disabling conditions such as multiple sclerosis (MS) are less likely to participate in routine mammography screening than women without disabilities due to multiple barriers. Underuse of mammography screening may lead to a diagnosis of a later stage breast cancer and consequently higher breast cancer mortality rate. This study examined the influence of several factors including, severity of MS-related functional limitations, demographic characteristics, family history of breast cancer, beliefs related to mammography screening and breast cancer, and personal resources on usual screening mammography in a sample of women with MS. The conceptual framework guiding this study was synthesized from The Explanatory Model of Health Promotion and Quality of Life in Chronic and Disabling Conditions and the Health Belief Model. Data from an ongoing longitudinal study (R01NR003195) focused on health promotion of persons with MS were combined with primary data for this prospective descriptive correlational study. The nonprobability sample consisted of 274 women ages 39-85 years who were primarily White (92%), married (66.1%), and unemployed (64.1%) with a 22 year average length of diagnosis with MS. Data were collected over two years using a mailed survey. Descriptive statistics and hierarchical logistic regression analyses were used to address the research questions. The annual mammography rate in this sample was 62%. Perceived susceptibility to breast cancer (AOR = 3.0, p < .05), family history (AOR = 2.5, p < .05), economic adequacy (AOR = 1.6, p < .05), and perceived barriers to mammography (AOR = .98, p < .05) significantly predicted mammography use, adjusted for severity of functional limitations. Though severity of limitations was negatively associated with mammography, it was not a significant predictor in the overall model. These findings suggest that for women with chronic disabling conditions, health beliefs, family history, and personal resources influence mammography screening. Clinicians need to continue to eliminate the barriers to mammography screening to improve screening and reduce overall breast cancer mortality rate in this vulnerable population. / text

The aim of the study is to assess the connection between women’s participation in breast cancer screening and beliefs towards breast cancer, breast self-examination and mammography. The objectives of the study: 1. To assess validity and reliability of Champion Health Belief Model Scale for beliefs towards breast cancer, breast self-examination and mammography screening for Lithuanian women. 2. To estimate perceived susceptibility, perceived severity, perceived benefits, perceived barriers, confidence and health motivation. 3. To compare beliefs towards breast cancer, breast self-examination and mammography screening of participant and non-participant women in the screening program. 4. To assess perceived barriers towards mammography screening. 5. To investigate the role of information about breast cancer and mammography screening for women‘s beliefs towards breast cancer, breast self-examination and mammography screening. CONCLUSIONS 1. Champion Health Belief Model Scale is a valid and reliable to assess beliefs towards breast cancer, breast self- examination and mammography. The barriers- mammography item “Regular mammography screening would make me worry about breast cancer” was inappropriate to the scale and expunged from the questionnaire. 2. Surveyed women did not feel much threat to get breast cancer. They overvalued benefits of breast self-examination and positively rated mammography screening. However, confidence to perform breast self-examination was properly low...

While sisters of breast cancer patients are at increased risk for developing breast cancer due to their family cancer history and age, little research with first-degree relatives of cancer patients has focused solely on sisters. To address this issue, the current study examined sisters screening and health behaviors and the predictors of these behaviors. In accordance with the Parallel Processing Theory, the current study assessed the relationship of cognitive and emotional factors to screening and health-promoting behaviors among sisters of breast cancer patients. In addition, this study expanded upon the Parallel Processing Theory by also examining the relationship of interpersonal factors to screening and health-promoting behaviors. One-hundred-twenty sisters of breast cancer patients from 89 different families completed questionnaires assessing perceived risk of breast cancer, perceived response efficacy of mammography, diet, and exercise, breast cancer worry, trait anxiety, involvement in sister's cancer care, satisfaction with the sister relationship, mammography screenings, physical activity, and amount of fruits and vegetables consumed. Findings indicated that cognitive, emotional, and relational factors were significantly related to mammography screenings, but not to diet or exercise. Specifically, response efficacy for mammography screening was positively related to mammography screening; while trait anxiety and involvement in sister's care were negatively related to mammography screening. Additional analyses indicated that breast cancer worry had a curvilinear relationship with mammography screenings, such that no relationship was seen for women with lower breast cancer worry; for women with higher levels of worry, the greater their worry, the less likely they were to obtain mammography screenings. Breast cancer worry was also found to interact with involvement in care, such that among women less involved in their sister's care, greater breast cancer worry was associated with having fewer mammography screenings. However, for women more involved in their sister's care, greater breast cancer worry was associated with having more mammography screenings. Future research should further assess whether a teachable moment exists related to the family member's cancer diagnosis and treatment during which to encourage the FDR to engage in screening health-promoting behaviors.

Objectives: Ductal carcinoma in situ (DCIS) is a non-invasive lesion of an increasing clinical importance. Individual risk assessment is essential for an optimal treatment. Our objective was to identify clinical and molecular characteristics of a subgroup of DCIS with an unfavorable prognosis. Methods: In a population study, we analyzed women with DCIS diagnosed within one mammography screening unit. In the experimental part of this work, we conducted a comparative analysis of five biological markers in normal tissue, DCIS and invasive breast cancer by means of gene expression analysis and analysis of loss of heterozygosity (LOH). Results: We demonstrated a high proportion of pure (no invasive component) DCIS (14.41%) of all breast lesions described as malignant. In our sample, we saw a homogeneous distribution of risk factors without noting a clear pattern identifying high-risk subtypes. We noted significant differences in clinical management of tumors with similar characteristics, which demonstrates the present state of limited use of clinical predictors. In the laboratory experiment, we showed differences in loss of heterozygosity (LOH) between DCIS and invasive breast cancer for BRCA1 (8.69% vs. 44.74%) and BRCA2 (9.52% vs. 45.0%). In contrast, we did not find any differences for p53 (31.82%...

This dissertation focuses on women’s participation in mammography screening, which is a vital component of early detection and effective management of breast cancer. All Swedish women in the age group of 40-74 receive an invitation by mail at regular intervals of 18-24 months. However, about 20% of Swedish women fail to attend the mammography screening they were offered. The impact on mortality within a population is contingent on theparticipation rate, underscoring the importance of making efforts to attain a high level of participation. This thesis is an attemt to improve understanding and awareness of the women’s choices and actions that can influence life or death, especially considering that being a woman is the most significant risk factor for breast cancer. The overall aim of this thesis was to explore the phenomenon of women’s participation in mammography screening by exploring the reasons why women refrain from mammography screening from the perspective of non-attending women (Paper I) and factors that affect women’s participation in mammography screening in the Nordic countries. The research was conducted through qualitative and mixed studies review method studies. The data collection methods comprised ten personal interviews (Paper I), and 16 articles (Paper II). Qualitative content analysis was used to analyse the interviews in an indictive approach (Paper I). A deductive approach with segregated mixed research synthesis was used to analyse and summarise findings from articles in systematic review (Paper II). Health Promotion Model by N. Pender was used as a theoretical framework. Participation in mammography screening is a complex phenomenon that has many dimensions. The thesis results underscore the significance of comprehending the unique and subjective encounters of women in the context of mammography screening. These experiences hold substantial sway over their perspectives and actions regarding this procedure. Additionally, the research suggests that effective communication and prior experiences, whether positive or negative, play pivotal roles in shaping women's knowledge and attitudes towards mammography. These findings align with the biopsychosocial perspective, which underscores the intricate interplay of biological, psychological, and social factors in individuals' lives. Mammography screening, as demonstrated in Paper I, operates as a standardized system aimed at addressing the diverse and individual needs of women. Various factors, such as individual characteristics, past experiences, cognitive factors related to behavior, emotional aspects, competing priorities, and the organizational aspects of screening, collectively influence women's participation in both positive and negative ways (Paper II). Promotional efforts are essential to motivate women to actively engage in their healthcare.

Abstrakt    Bakgrund: Bröstcancer är en av de vanligaste cancerformerna hos kvinnor runt om i världen och utgör en betydande risk för hälsan. För utrikesfödda kvinnor finns särskilda utmaningar när det gäller att gå på mammografiscreening, vilket kan ha allvarliga konsekvenser för deras hälsa. För att säkerställa att alla kvinnor får likvärdig vård och att fler deltar i screeningen är det viktigt att identifiera och lösa dessa hinder. Röntgensjuksköterskor spelar en viktig roll genom att ge stöd, information och skapa en trygg miljö för patienter under mammografiscreening. Genom att förstå och hantera de hinder som utrikesfödda kvinnor möter kan vi sträva mot ett mer inkluderande och effektivt vårdsystem.   Syfte: Syftet med denna studie är att undersöka vilka hinder som utrikesfödda kvinnor möter när det gället att delta i mammografiscreening.  Metod: Studien genomfördes med en kvalitativ metod litteraturöversikt enligt Fribergs metod, där nio artiklar valdes ut för analys och granskning. Sökningen utfördes genom PubMed och Cinahl via Umeå Universitets bibliotekstjänst.  Resultat: Resultaten visade på flera hinder som hindrade utrikesfödda kvinnor från att delta i mammografiscreening. Dessa hinder kategoriserades i tre övergripande huvudkategorier och tio underkategorier: Strukturella hinder, Sociokulturella hinder och Emotionella hinder. Underkategorierna inkluderade bland annat språkbarriärer, bristande kunskap om sjukdomen och screeningen, ekonomiska begränsningar, transportsvårigheter, fatalism, skam och rädsla för smärta.  Konklusion: Sammanfattningsvis visar denna litteraturstudie att utrikesfödda kvinnor möter flera hinder när det gäller att delta i mammografiscreening. För att öka deltagandet är det viktigt att erbjuda anpassad information och stöd samt skapa en trygg och respektfull vårdmiljö. Genom att hantera dessa hinder kan hälso- och sjukvården främja jämlik tillgång till och deltagande i screeningen, vilket är avgörande för tidig upptäckt och behandling av bröstcancer. / Abstract  Background: Breast cancer is one of the most common forms of cancer affecting women worldwide, posing a significant health risk. Immigrant women face specific challenges when it comes to attending mammography screening, which can have serious consequences for their health. To ensure equitable care for all women and increase participation in screening, it is essential to identify and address these barriers. Radiographers play a crucial role by providing support, information, and creating a safe environment for patients during mammography screening. By understanding and addressing the obstacles faced by foreign-born women, we can strive towards a more inclusive and effective healthcare system.  Aim: The aim of this study was to investigate the experiences of immigrant women regarding barriers to participating in mammography screening.   Methods: The study was conducted using a qualitative method of literature review following Friberg's methodology, where nine articles were selected for analysis and review. The search was performed through PubMed and Cinahl via Umeå University's library service.  Results: The results revealed several barriers hindering immigrant women from participating in mammography screening. These barriers were categorized into three overarching main categories and ten subcategories: Structural barriers, Sociocultural barriers, and Emotional barriers. Subcategories included language barriers, lack of knowledge about the disease and screening, economic constraints, transportation difficulties, fatalism, shame, and fear of pain.  Conclusion: In summary, this literature review highlights that immigrant women encounter multiple barriers to participating in mammography screening. To increase participation, it is crucial to provide tailored information and support and create a safe and respectful healthcare environment. By addressing these barriers, healthcare providers can promote equitable access to and participation in screening, which is essential for the early detection and treatment of breast cancer.
