Key legal question
Whether cancer-related fatigue should be assessed by analogy to somatoform pain disorder case law and treated as overcomeable by willpower
Extracted holding
No. Cancer-related fatigue is not to be equated with somatoform pain disorders; the analogy is not justified.
Extracted reasoning
The syndrome is medically distinct, multifactorial, and at least indirectly based on an organic cause linked to cancer or its treatment; no basis exists to import the rules developed for somatoform pain disorders.
