Breaking bad news represents a challenge for professionals working in palliative care, with obstacles that need to be understood. To unveil them, the objective was to analyze the perspective of physicians who work in palliative care with adults about breaking bad news. A qualitative research was carried out, with the participation of nine physicians working in palliative care, in public and private hospitals, with experience in the specialty between 2 and 18 years. They answered to a semistructured script, containing the following themes: breaking bad news, professional training and difficulties in this practice. The data were analyzed using the IRaMuTeQ. The results were organized into five classes that present: 1) the importance and deficiencies in the training and practice of professionals; 2) the necessary care in the communication process; 3) the reaction of patients and their families to the diagnosis and prognosis in palliative care; 4) the integration between team and family in palliative care and; 5) the importance of checking patients' understanding of communication. It is concluded that breaking bad news in palliative care is a challenge that requires theoretical knowledge and skills in Medical and Health Psychology, which need to be emphasized in professional training.
