The Challenges of Cancer Pain Assessment

Cancer pain is not a single entity. It incorporates a range of aetiological, pathophysiological and anatomical subtypes, all requiring unique descriptive terminology, assessment techniques and treatment modalities. The tumour itself can press on bones, nerves and other organs. Chemotherapy drugs can cause pain at the site of administration or limb paraesthesia. Radiotherapy can cause skin erythema and organ irritation.
