Background: Breast cancer is the most common cancer among females in the United Arab Emirates (UAE). It carries poor prognosis when detected late. Patients usually present at late stages due to lack of awareness of various aspects of breast cancer. Aim: The objective of this study is to gain insight into the level of knowledge of breast cancer among young adult females in UAE. Methods: A cross-sectional study was conducted among females aged 25 to 45. A total of 492 females were selected using a convenience sampling method. Data were collected through an interview-based questionnaire. Frequency distributions and percentages were used to describe the knowledge tested within the questionnaire. Results: The mean age of the participants was 33.5 years. Almost 27% of our participants received a high school degree. The average total knowledge of our population was 51%. The majority (89%) knew that breast cancer is common and 45% knew that it affects ages above forty. The knowledge of signs and symptoms was 53%, and more than half (57%) knew that the most common presenting sign is a breast lump. The knowledge of risk factors was 43%. Almost 94% knew that cancer can be detected early, and 93% knew that early diagnosis improves outcome. The total knowledge of screening methods was 67%. Conclusion: The study revealed that respondents’ knowledge of breast cancer is less than expected. The increased burden of the disease should be accompanied by powerful means of spreading awareness by implementing campaigns that would improve knowledge deficits.

Photoactive aluminum doped ZnO(AlZnO)was synthesized by sol-gel *** that,AlZnO photocatalyst was deposited on five carbon-based materials(CBMs)using ultrasonic route followed by solid-state mixing using ball *** CBMs used were poly aniline(PANI),carbon nitride(CN),carbon nanotubes(CNT),graphene(G),and carbon nanofibers(CNF).The crystal phases,elemental compositions,morphological,and optical properties of the AlZnO@CBMs composites were *** results revealed that two of AlZnO@CBMs composites exhibited superior bleaching efficiency(100%removal)and photocatalytic stability(three cycles)for 50μmol/L Methylene Blue(MB)contaminated water after 60 min irradiation in visible light at pH 6.5,0.7%H2O2,and 5 g/L inorganic *** optimum conditions,AlZnO@CBMs nanocomposites were employed for the treatment of mixed dyestuffs composed of MB,Methyl Orange(MO),Astrazone Blue FRR(BB 69),and Rhodamine B(RhB)dyes under dark,ultraviolet,visible,and direct *** mixed dyestuffs,the AlZnO@G achieved the highest dye sorption capacity(60.91μmol dye stuffs/g)with kinetic rate 8.22×10^-3 min^-1 in 90 min via multi-layer physisorption(Freundlich isotherm)on graphene *** additions,AlZnO@CN offered the highest photo-kinetic rate(Kphoto)of^54.1×10^-3 min^-1(93.8%after 60 min)under direct ***,the selective radical trapping experiment confirmed that the holes and oxidative superoxide radicals are crucial on dyes photodegradation *** to their superior performance,AlZnO@G and AlZnO@CN nanocomposites can offer an effective in-situ solar-assisted adsorption/photocatalytic remediation of textile wastewater effluents.
