What is cancer fatigue?

 

Fatigue means tiredness and lack of energy. For people with cancer, this can be severe and last a long time. Cancer or its treatment can cause fatigue.

 

Fatigue makes you feel like you can't do things at your normal pace. We all feel this at times, like when we're working too hard, worrying about something or overdoing the socialising.

 

Not eating properly or taking too little exercise can make it worse.

 

With this type of fatigue, your body is letting you know that you are overdoing it. The tiredness is usually short term and you feel better after you stop and rest.

 

Fatigue for people with cancer might not go away even when you rest. It can go on for weeks, months or even years after you finish treatment. This is called chronic fatigue, which means long lasting. Most people get back to their normal energy levels from between 6 months to a year after the end of cancer treatment. But it can take longer.

 

Fatigue is very common in people with cancer. It can be the most troubling symptom. It affects between 70 and 80 out of every 100 people (70 to 80%). Many people say it's the most disruptive side effect of all.
