Empathy has been identified as an important communication skill that can improve psychological outcomes for patients with cancer and palliative care patients; as such there is a need for cancer nurses to be empathic. The majority of research that has been carried out has been concerned with the definition and measurement of empathy. Exploration into the concept of empathy has shown that there is a need to examine the nature of it and to identify exactly where it succeeds and fails. The questions of how empathy is nurtured and sustained and under what conditions it flourishes and diminishes need to be addressed. This study aimed to investigate how cancer nurses interpret and acquire empathy, and to identify the conditions that influence it. It was also important to establish what cancer nurses considered to be the benefits and disadvantages of expressing empathy. The findings demonstrated that nurses are aware of the concept of empathy and do use their empathic skills; however, there are barriers that could inhibit the expression of empathy, including lack of time, poor environment and communication difficulties. This study highlights the recognition of empathy as a discrete communication skill and the need for more structured courses.
