[Better understanding of cancer-related fatigue]

Cancer-related fatigue (CRF) is a major reality during treatment as well as once treatment is completed. For many people, CRF persists for long periods in the post-therapeutic phase and has a considerable negative impact on the quality of life. Fatigue is defined as a subjective and multidimensional phenomenon. CRF is associated with many factors, hence its complexity. The goal of this article is to summarize major findings from a review of literature in order to better understand the phenomenon of CRF itself, its progressive course, the main associated factors and some of the most promising interventions.
