AIM: The aim was to improve the knowledge and understanding of how newly diagnosed advanced prostate cancer affects the men and their life situation and perhaps causes fatigue before the side effects of any treatment has an impact on them. METHOD: The qualitative study where ten men, newly diagnosed with advanced prostate cancer and at an early stage in their treatment, were interviewed. The interviews were analysed by using Gadamer's hermeneutics. RESULTS: The men in the present study did not experience fatigue specifically because they had been diagnosed for advanced prostate cancer. Three topics were identified during the analysis and interpretations: awareness of mortality, the influence on their emotions and the influence on their normal life. These topics offered a structure presenting the essence; the need to get back to as normal a life as possible, albeit with a new perspective. The topics together confirmed an affected life situation, which in turn helped the participants to form a new perspective on life. CONCLUSION: The knowledge and understanding of the study is that advanced prostate cancer affects men's lives: they are placed in a new life situation, against their will, and in their new situation they form a new life perspective. Healthcare professionals need to evaluate, perceive and furthermore understand the men's apprehensions and expectations, on an individual basis, for their future and empower them to formulate a new life perspective.
