A new study just published in the Journal of Clinical Oncology shows that Cognitive Behavior Therapy (CBT) can help cancer survivors who are experiencing severe fatigue and functional impairment. If you know someone who has been cured of his or her cancer, but has unexplained fatigue, you may want to check out this study. 112 cancer survivors with severe fatigue were randomly assigned to one of two groups -- half of them received CBT, and the other half was assigned to a waitlist for therapy (i.e. they did not receive therapy during the six month timeframe of the study). The group that received CBT treatment showed significantly reduced fatigue and functional impairment as compared to the control group.
