KLK3 and cancer: After ending curatively intended treatment, patients have outpatient follow-ups, including at least two prostate-specific antigens (PSA) measurements during the first year.3 In Sweden, physician appointments are generally scheduled three months after treatment ends, and patients are encouraged to contact their cancer nurse when needed.13 Hence, most of the time during this phase, patients are at home and left to manage concerns and symptom distress by themselves,14 which implies finding and utilising specific and relevant information.15
