Cancer related fatigue

Fatigue is a feeling of physical, emotional, and/or mental exhaustion. Cancer related fatigue is different from regular fatigue because it doesn’t go away once you get some sleep or rest. Most people dealing with cancer experience some level fatigue.

Symptoms of cancer related fatigue

Your experience of exhaustion and cancer will be unique to you – and it can change throughout your treatment. Your fatigue symptoms during the early diagnosis period can differ from what you experience during treatment and may change again in your recovery period. You’ll most often notice fatigue while your cancer is being treated and afterwards, but your energy levels will usually improve over time.

Cancer related fatigue symptoms can include:

  • Having little or no energy
  • Feeling mentally and/or emotionally exhausted
  • Muscle aches and pains
  • Feeling weak all over
  • Difficulty thinking clearly or concentrating
  • Trouble getting through daily tasks like dressing, showering or cooking
  • Sleep related issues, either sleeping too much or not getting enough
  • Feeling sad or irritable

Diagnosing fatigue

Screening questionnaires and body analysis tests will guide your healthcare team to best measure your cancer related fatigue. They’ll want to know things like when your fatigue started, how it has changed, and what impact it’s had on your day-to-day life.

Blood, urine and heart function tests will determine your blood cell count, hormone levels, kidney and liver function. Sometimes, conditions like anaemia or low hormone levels can cause fatigue, and they can be identified and treated.

Fatigue during and after treatment can vary. These guidelines can help you rate your experience when talking to your doctors about treatment:

  • Mild fatigue (0–3): Able to keep doing usual activities
  • Moderate fatigue (4–6): Reduce symptoms and increase your energy levels gently
  • Severe fatigue (7–10): Reduce symptoms and save your energy

Managing fatigue

Your GP can refer you to health professionals like an occupational therapist, physiotherapist or exercise physiologist to help manage your fatigue. Costs vary for these services, but you might be eligible for five free visits a year under a GP-referred General Practitioner Management Plan.

Other tips to help you manage cancer fatigue include:

Daily habits and sleep

  • Pace your days and plan breaks and rest when you need to
  • If you’re not sleeping well, talk to your doctor
  • If you nap during the day, keep it short and aim for 7 to 8 hours of sleep at night
  • Avoid alcohol and smoking because these can disturb your sleep
  • Try meditation or relaxation techniques with your bedtime routine

Wellness and self-care

  • Regular meditation helps calm the mind and soothe the nervous system
  • Consider therapies like yoga, tai chi, qi gong
  • The Chinese herb American Ginseng can help with fatigue (consult your doctor first)
  • Some research suggests acupuncture can help with fatigue

Reach out to others

  • Communicate with your friends and family to help them understand how you’re feeling
  • Some councils offer social services, like someone to help with chores or grocery shopping
  • Talk with your doctor if you’re feeling down for long periods – this could indicate you have depression, which can be treated
  • Cognitive behavioural and mindfulness-based stress reduction therapies can help to improve mood
  • Support groups can help you feel understood, and reduce feelings of isolation – in person, online forums and closed social media groups, or over the phone

Questions you may have…

Does cancer make you tired all the time?

Exhaustion and cancer do often align. This is a common complaint while someone is going through their cancer treatment, and for some time after. Cancer exhaustion and fatigue usually improve over time.

Cancer fatigue vs regular fatigue?

Cancer related fatigue is felt even after the person has slept or had good rest. For regular fatigue, the body usually feels rejuvenated after sleep or rest.

What type of cancer causes fatigue?

Cancer alone does not cause fatigue. Cancer fatigue is often a combination of the cancer, the method of treatment (chemotherapy, radiation therapy, or immunotherapy), medications, and treatment side effects such as low blood cells (anaemia). Also, the stress of treatment and not eating or sleeping well can add to feeling exhausted.

How long does cancer related fatigue last?

Cancer fatigue is experienced for many people going through their cancer treatment, and for some time after treatment has finished. It takes time for cancer related fatigue to reduce and for energy levels to improve, and unfortunately for some it can take years.
