In Saudi Arabia, breast cancer ranked the first among females in 2014, accounting for 15.9% of all cancers reported among Saudi nationals and 28.7% of all cancers reported among females of all ages. Early detection of breast cancer could decrease the risks, have a better prognosis, and have better outcomes/more successful treatments. Prevalence of breast cancer reached more than 25% of all diagnosed cancer in the kingdom among women. Aim: This study aims to assess the knowledge and performance of women attending primary care centers about breast self-examination and mammogram screening for prevention and early detection of breast cancer in Abha city primary healthcare centers, Kingdom of Saudi Arabia. Research Method: cross sectional design was conducted by using questionnaire, which was distributed to primary care center nurses. The collected data was statistically analyzed using the Statistical Package for Social Sciences, version 25. Results: The study found that participants had poor awareness and knowledge about breast self-examination, risk factors for breast cancer, and trends and practices in early diagnosis of breast cancer. Conclusion and Recommendations: It recommends increasing awareness campaigns and providing educational programs to improve knowledge and practices.展开更多

It creates spaces that strongly promote social and cultural behavior. Meanwhile, life developments and the stunning technological acceleration along with high population densities have led to many problems for the old cities and their centers, which were not prepared to address these problems. Most of these problems have caused much visual deterioration and economic recession for the centers of old cities, which raise the importance of finding alternative and flexible solutions to prevent damage in urban performance, environmental pollution and lack of requirements that affect the quality of life. The paper aims to present a vision that opens up prospects for subsequent research contributions that may contribute to improving the quality of life, inspired by sustainability and humanization features. The research relies on an inductive analysis method to develop a framework that contributes to the restoration of the old centers for their role, their aesthetic value and their functional importance, while facilitating movement and supporting their valuable architectural features.展开更多
