An introductory overview for this topic. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
Oncological emergencies are a group of conditions that occur as a direct or indirect result of cancer or its treatment that are potentially life-threatening
These include:
Hypercalcaemia
Neutropaenic sepsis
Tumour lysis syndrome
Leukostasis
Raised intracranial pressure
Spinal cord compression
Cauda equina syndrome
Superior vena cava obstruction
Syndrome of inappropriate antidiuretic hormone secretion (SIADH)
Disseminated intravascular coagulation
How this connects to Medical Oncology
Cancer biology involves abnormal clonal growth, tissue invasion and interactions with immune, stromal and vascular components. Tumor type, grade, stage and molecular findings answer different questions; diagnostic and treatment decisions require tissue-specific evidence and multidisciplinary clinical assessment.

What the underlying subject studies
At postgraduate and higher-specialty level, begin with normal anatomy and physiology of the relevant organ system, then compare distinct disease mechanisms, their evidence base and the limitations of available investigations.
How mechanisms and evidence connect
Advanced study requires evidence appraisal, multidisciplinary interpretation and a clear distinction between established facts, hypotheses and research findings. Procedural, diagnostic and prescribing skills must be learned under an accredited program.
How to develop a sound explanation
Identify the scope of this topic within the named specialty, connect it to the applicable patient population and formulate a structured question that can be answered using current specialty literature and supervised teaching.
