Nurses working in oncology frequently have to make tough moral choices, such as how to break bad news or how to make sure a dying patient receives good palliative or end-of-life care. In the context of patient care, this may limit the ethical and moral options available to nurses. This can cause moral dissonance and ethical insensitivity on the job and can be very stressful. To be able to meet ethical problems in trying times calls for capacity to recognize and know how to manage the concerns. The purpose of this article was to describe common ethical challenges and to present some methods that may be helpful when confronting them. This narrative review discusses the ethical standards that oncology nurses should uphold and implement in their daily work. Many common ethical dilemmas are also explored, and the study hopes to shed light on how novice nurses, such as students and fresh recruits, may experience when caring for cancer patients and their family caregivers. Importantly, this review also addresses aspects of how nurses can improve their skills so that they can deal with the ethical quandaries and moral discomfort that arise on a daily basis in cancer care.
