Background: When a child is diagnosed with cancer it will change the life for the whole family. The safe everyday life is converted into concern and fear, and a new life with hospital visit, medicines and treatments begins. Aim: The aim of the study is to describe how parents experience their lives when their children suffering from cancer. Method: A literature- based study based on ten qualitative articles. The articles were analyzed and the result were compiled. Result: The study found that in the course of cancer diagnosis, the parents felt that their whole world was turned upside down. The disease affected the relationship with the siblings, as well as the parents' own health. The changing work situation contributed to the deterioration of the economy, and new priorities arose in everyday life. Support from other people was considered to be an important component to cope with the difficult situation. Many parents also sought spiritual support and comfort in religion, which in turn helped them find and feel hope. Conclusion: Through greater knowledge and understanding, the nurse can support the parents through the different feelings that can arise when the child becomes ill with cancer.
