As many as nine out of ten people people experience cancer related fatigue (CRF) at some time.
Fatigue is very different from everyday tiredness as it lasts longer and can come on without warning.
The causes of CRF are not fully understood. It may be caused by the cancer itself, the symptoms or be a side effect of treatment.
It is important to remember that your feelings of fatigue are unique and personal to you and managing it can be greatly helped by gaining a better understanding of what has a positive or negative effect on your energy levels.
