Oncology Nursing Day is observed in Canada every first Tuesday of April, established in 2003 to recognize the vital role of oncology nurses in the healthcare system. This day celebrates their dedication and expertise in caring for cancer patients throughout their treatment journey, from screening to end-of-life care. Oncology nurses work in various settings, including hospitals and cancer centers, and are responsible for tasks such as monitoring patient conditions, managing symptoms, and providing emotional support. The Canadian Association of Nurses in Oncology (CANO/ACIO) organizes professional events like seminars, webinars, and awards ceremonies to honor these healthcare professionals. The demand for oncology nurses continues to grow due to the aging population and rising cancer rates in Canada.
