How common is persistent fatigue in anxiety and low mood with cancer?

Persistent Fatigue is a common presentation of Anxiety and Low Mood With Cancer. Fatigue may occur alongside emotional distress, but fatigue by itself does not show that anxiety or low mood is the cause.

Worry, sadness and prolonged stress can make sleep less restorative, reduce appetite and drain mental energy. Cancer symptoms, treatment effects, pain, anaemia, infection and disrupted routines can add physical tiredness. Someone may feel slowed down, find concentration harder, or lose interest in usual activities. These experiences deserve attention because physical and emotional causes can coexist and may need different forms of support.

Describe both your energy and your mood to the cancer team, including sleep, appetite, concentration, motivation and worries. Small routines such as gentle movement, regular meals, daylight and a consistent sleep time may help when suitable for your health. Ask about counselling, psycho-oncology, support groups or medication review. Do not stop prescribed treatment without discussing it with the prescriber.

Seek urgent help if you have thoughts of harming yourself, feel unable to stay safe, become confused, or cannot eat, drink or manage essential care. Contact your clinical team promptly for sudden fatigue, fever, new breathlessness, severe weakness or a marked change in mood. Emotional distress is a health concern and does not need to be endured alone.

Could a physical problem be adding to my fatigue? What support is available for sleep, worry or low mood? Would a medication review or talking therapy suit me? Who should I contact if my mood worsens outside clinic hours?
