Knowledge about Risk Factors for Breast Cancer and Having a Close Relative with Cancer Affect the Frequency of Breast Self-Examination Performance

Breast Cancer Knowledge and Practice of Breast Self-Examination among Female University Students, Gaza

Breast cancer is the highest public detected cancer among female population in the majority of countries worldwide. Breast self-examination (BSE) is a useful screening tool to empower women and raise awareness about their breast tissues and help detect any breast abnormalities when they occur. This study aimed to assess the level of female university students' knowledge and practice of BSE. A self-administered questionnaire was used to assess the knowledge about breast cancer and related items, and an observation checklist was used to test practicing BSE using a breast simulator. Eighty-six students participated in the study, 58.1% studying nursing and 41.9% studying clinical nutrition in the third (40.7%) or the fourth level (59.3%). Of them, 24.4% had previous family history of breast cancer. The majority of the students (80.2%) had previous information about breast cancer acquired from different sources, university studies (57%), the Internet (45%), and social media (41%). Findings showed good scores (≥70%) regarding signs and symptoms and risk factors of breast cancer; however, low knowledge scores (<70%) were detected regarding general knowledge about breast cancer disease, methods of early detection and management, and applying steps of practicing BSE. Roughly all the students (96.5%) have heard about BSE, and 69.8% knew the time to do BSE; however, only 31.4% practice it regularly. Three barriers to practice were dominant among students who do not have a breast problem (39.7%), do not know how to do it (37.9%), and being busy 31%. On the other hand, breast cancer early detection purpose and the presence of family history of breast cancer were considered facilitators to regular practice BSE. A statistically significant relationship existed between knowledge about the steps of applying the BSE and regular practicing. A training program should be implemented to increase the level of awareness about BC and practicing BSE.

Breast Cancer Risk Perception and Mammography Screening Behavior of Women in Northeast Brazil

Background: Previous studies suggest that education and income affect Brazilian women's breast cancer prevention behavior. The present study focused on the impact of perceived and estimated risk on mammography screening (MS) behavior. Materials and Methods: Information regarding socioeconomic variables and risk perception was obtained from 396 healthy women aged 40-79 years. Perceived comparative risk was measured on a seven-point Likert scale. A Breast Cancer Risk Assessment Tool of 5-year risk to develop breast cancer was used to determine objective risk. Estimated comparative risk was determined as categories of perceived risk relative to the objective risk. Regression analysis was applied to determine odds ratios (ORs) and confidence intervals (95% CIs) of variables. Results: Asked about the potential of MS to lower risk of death because of breast cancer, 215 (54.29%) responded that it does not lower risk. Women with low perceived comparative risk had a twofold (OR = 0.493; 95% CI: 0.24-1.00) decreased chance to participate in MS annually, compared with women with high-perceived comparative risk (p = 0.020). Women without family history had a 7.6-fold (OR = 0.132; 95% CI: 0.07-0.25) decreased chance of having a high-perceived comparative risk (p = 0.000). If compared with underestimation, the overestimation and accurate estimation of comparative risk tended to be associated with a decreased chance of MS attendance (p = 0.017). Regression modeling indicated that low educational level, no occupation, and no family history decreased the chance of women having MS (p = 0.040; p = 0.010; p = 0.022). Conclusions: Risk perception depended on family history. Present data did not indicate that overestimation, or accurate estimation of comparative risk, increased chance of MS attendance. Educational level, occupation status, and family history, instead, determined MS performance.

Impact of a Breast Cancer Educational Program on Female University Students' Knowledge, Attitudes, and Practices

Breast cancer (BC) is a worldwide fatal cancer among females. Efforts fighting against this disease should start with females at younger ages. This study evaluated the effectiveness a BC educational program in promoting female university students' knowledge and attitudes towards BC and practices of breast self-examination (BSE). A pre- and post-test design was used in two phases; pre- and post-intervention phase. A 1-day educational program was conducted with theoretical and practical educational sessions. Participants were evaluated twice (before and 2 weeks after the intervention) for the following variables: knowledge regarding BC warning signs, BC risk factors and knowledge in regard to BSE, in addition to their attitudes and practices of BSE. A total of 110 participants were randomized into either intervention (n = 64, 58.2%) or control group (n = 46, 41.8%). Analysis revealed that participants in both groups had relatively low level of knowledge, negative attitudes, and poor practice towards BC and BSE before attending the intervention. Analysis of the post test revealed that participants in the interventional group had significant improvement in knowledge, positive attitudes, and more practice of BSE compared to participants in the control group. The implementation of a BC awareness program had positive effects on the female university students' knowledge, attitudes, and practices regarding BC and BSE. Findings from this study strengthen and reinforce the importance of conducting such awareness programs for this young age group.
