For many people, Hengshan Street is a landmark. On this street, bars in bold and unrestrained styles appeal to visitors. In fact, the whole street is a large open bar: the hurly-burly of "Hello" permeates every corner of the street; the resonant singing of "Rainbow Potato" echoes in the night sky; the rock’n roll of "Full House" fascinates passers-by with the wildness of John Lennon;展开更多

The diagnosis, living with the disease, as well as the different treatments can have important impacts on the Psychological and mental health of patients. Objective: To investigate the psychological aspects that women with breast cancer develop or may develop. Methodology: A systematic review using the PRISMA methodology was used. Results: 11 articles that met the inclusion and exclusion criteria were analysed. The largest flow of publications in relation to the effects of the patient with cancer, were carried out between the years 2000 and 2023. Conclusions: Psychological disorders (depression, anxiety, stress) are part of the lives of women diagnosed with breast cancer, and their prevalence varies from one woman to another.展开更多
