Cancer Patients’ Common “Post-Treatment Fatigue Syndrome”
Helping you understand “why you still feel completely drained even after treatment ends” — and gentle ways to improve
Many cancer patients enter a phase known as “Cancer-Related Fatigue” (CRF) after completing chemotherapy, radiotherapy, or surgery.
Even when the tumour is under control and test results appear normal, patients often feel “no matter how much I sleep, I’m still exhausted”, “always low on energy”, or “even simple household tasks feel overwhelming”.
This is not a matter of “psychological factors” or “not being strong enough” — it is the long-term impact of treatment on the body’s energy systems, nervous system, and immunity, making fatigue the most common and persistent side effect after treatment, affecting quality of life and rehabilitation progress.
