the objective of this study is to identify the conceptions of nurses who work with pediatric oncology concerning how their training and the further search for knowledge influences their professional practice. it is a qualitative, exploratory type study with semi-structured interviews applied to six nurses. the results were submitted to thematic analysis, which converged to the category, "subsidies that influence the pediatric oncology nursing care production". the results show that pediatric oncology performance demands professionals with responsibility, commitment, adequate preparation, and sensitivity to take care of the child at hand. care production has been grounded in the individual experiences of nurses and individual pursuit of knowledge, demonstrating the difficulties encountered in the training process and the importance of professional training. it is believed that these findings may support nursing training with a problematzing perspective and be able to promote comprehensive, humane, and efficient care for children diagnosed with cancer.
