Oncological emergencies refer to life-threatening situations that require prompt treatment in cancer patients. Some examples include tumor lysis syndrome, hypercalcemia, neutropenic fever, spinal cord compression, and superior vena cava syndrome. Prompt diagnosis and treatment are crucial to prevent serious complications or death. Treatment may involve chemotherapy, radiation, surgery, or other supportive measures depending on the specific emergency. Nursing care focuses on symptom management, infection prevention, nutritional support, and palliative care.
