Cancer-Related Fatigue Facts
This fact sheet addresses some common questions that people may have about cancer-related fatigue--likely causes, how it is measured, treatment options and self-care tips. As with any cancer-related symptom or side effect of treatment, it's important for individuals to tell members of their oncology team if and when they feel exhausted.
More than half of the people diagnosed with cancer experience cancer-related fatigue (CRF), which is characterized by excessive and persistent exhaustion that interferes with daily activity and function. CRF often begins before cancer is diagnosed, worsens during the course of treatment, and may persist for months--even years--after treatment ends. Fatigue can be difficult to assess because there are no objective measurements.
