As a complement to quantitative studies, qualitative studies give us a better understanding of how persons affected by lung cancer live their everyday lives and how they deal with the obvious strain of having lung cancer. Because qualitative studies are based on only a few participants in specific contexts, the purpose of the present study is to synthesize knowledge from these qualitative studies to get a more general picture of the everyday lives of patients with lung cancer. A search on PubMed, CINAHL, Medline and PsychInfo yielded 383 hits. After exclusion we found 16 studies that focused on how these patients lived, reflected, and dealt with their new life situation. These studies comprised 393 interviews with 283 patients with primary lung cancer, and the findings from these studies were synthesized into a core process with subcategories. The overarching process was that the patients were eager "to carry on as before". They wanted to resume their former everyday life, and their views on their relationships with their bodies and side effects of treatments, their families, the health care staff, and with dying and death were very much related to how these could assist the core process. The synthesis presented here suggests that health care in consultations with patients with lung cancer should defer to the importance of the patient's core idea that life carries on despite the fact that it will probably soon come to an end.
