What distinguishes cancer-related fatigue from general fatigue?

Cancer-related fatigue is characterized by its persistent nature and does not improve with rest. This fatigue often stems from the biological processes related to cancer, including the disease itself, treatment effects, and psychological factors. Individuals experiencing cancer-related fatigue typically report a profound lack of energy that is different from the usual tiredness one might feel at the end of a busy day, which can be relieved by a good night's sleep or rest.

While general fatigue may be temporary and often goes away after adequate rest or recovery time, cancer-related fatigue tends to persist and can significantly impact daily functioning and quality of life. It is not exclusively linked to chemotherapy but can occur as a result of cancer itself or as a side effect of various treatments. Understanding the distinct characteristics of cancer-related fatigue compared to general fatigue is essential for proper management and support for individuals undergoing cancer treatment.
