Study protocol: Trough treating physicians, the investigators will identify 240 men in the Västra Götaland healthcare region who have been diagnosed with prostate cancer of intermediate risk-level (T1-T2, Gleason score <8, PSA<20)scheduled for radical prostatectomy. The clinic will be informed of which patients have been enrolled in the study, and the surgery for these patients will be scheduled six weeks ahead of time from the date of inclusion. Once a patient has agreed to participate, he will be randomized to one of the two intervention arms. The patient will then receive additional information depending on which group he belongs to and will be asked to donate a blood sample. Under normal clinical routine, data on all prostate cancer cases is collected in the National Prostate Cancer Register (NPCR), for example information on Gleason score, tumor volume, Prostate-specific antigen (PSA) levels. The investigators will collect information from the registry in connection with the analysis of data.
