When someone becomes seriously ill from cancer their relatives experience a great suffering from observing the changes in their loved ones as a result of the disease. They felt that they did not receive the support and information they needed to process their difficult lives.It also emerged that the relatives didn’t think the nursing staff treated and saw the family as a whole. The purpose of the study was to describe the suffering of families, as they experienced that during the final stages of a cancer patient's life. An inductive, manifest, content analysis has been carried out in five autobiographies written by relatives of patients, who had died as a result of cancer. Biographies were reviewed by the Graneheim and Lundman's method of analysis. We used Katie Eriksson’s scientific theories of care regarding suffering as a theoretical framework. The result has collected material presented in three categories: fear, sadness, and frustration which mirrors the suffering of relatives in these books. The results showed that the relatives denied the disease's existence, experienced a fear of the disease symptoms, death, and a future without the patient. The relatives describe the grief that they felt about the prospect of being left alone, about the patient's deterioration, and of not being seen as individuals. Finally the relatives describe the frustration they feel over the panic, stress, fatigue and anger that they experience in the end of the patients life.
