How common is night sweats in chronic myeloid leukaemia?

Chronic myeloid leukaemia affects blood-forming cells in the bone marrow and can produce whole-body symptoms. Night sweats may occur with persistent tiredness, fever, reduced appetite, unplanned weight change, pale skin or a feeling of fullness under the ribs from an enlarged spleen. Many people have no obvious symptoms early on, and night sweats have other possible causes, including infections, medicines and hormonal changes. A symptom by itself cannot diagnose leukaemia.

Make a timely appointment if night sweats are new, recurring or soaking your sleepwear, especially with tiredness, fever, bruising or fullness in the upper abdomen. Keep a brief record of episodes, temperature, other symptoms and medicines. A clinician may examine you and arrange blood tests; further care depends on the findings. Do not stop prescribed treatment without advice.

Seek urgent care for severe breathlessness, fainting, confusion, heavy bleeding, rapidly increasing weakness or a high fever while receiving cancer treatment. Contact your haematology team promptly for new fever, chills, unusual bruising or bleeding, or a sudden change in your usual symptoms.

Ask whether night sweats could reflect the condition, an infection or a medicine effect; which blood results matter; and whom to contact if fever or bleeding develops. Mention any change in appetite, weight, energy or abdominal fullness.
