Despite growing awareness of neurocognitive and psychological complications of systemic chemotherapy administration in breast cancer, prospective observational studies evaluating such effects in Egyptian breast cancer patients-especially with pre- and post-treatment assessments-remain limited. Given the rising incidence of breast cancer in Egypt and the growing population of long-term survivors, it is essential to investigate the extent and nature of cognitive and psychological changes associated with treatment. The current study aims to fill this gap by prospectively evaluating neurological, cognitive, and psychological parameters in newly diagnosed breast cancer patients, using validated tools before and one year after treatment.
