Investigating the psychological impact of active surveillance or active treatment in newly diagnosed favorable-risk prostate cancer patients: A 9-month longitudinal study.

Men undergoing AS had significantly higher anxiety symptoms than AT and non-cancer participants, contradicting previous literature. This may be due to perceived inactivity of AS relative to traditional narratives of cancer treatment. Participant experiences appear to be less favorable relative to other international centers. Recommendations for future research and clinical practice include the need to improve diagnosis and treatment information provision particularly for lower risk patients.
