Interventional radiologists care for a large number of cancer patients with the breadth of palliative intent minimally invasive procedures that we provide.

Common instruments used to measure pain and quality of life for cancer patients include the numerical rating scale, visual analog scale, brief pain inventory, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, and the Functional Assessment of Cancer Therapy.
