What therapy is associated with the side effect of fatigue in cancer patients?

Fatigue is a common side effect associated with chemotherapy in cancer patients. Chemotherapy works by targeting rapidly dividing cancer cells, but it can also affect normal, healthy cells that replicate quickly, such as those in the bone marrow, gastrointestinal tract, and hair follicles. As a result, patients may experience a range of side effects, including fatigue, due to various factors such as anemia (a reduction in red blood cells), the metabolic demands of recovering from treatment, and the emotional stress of a cancer diagnosis.

Fatigue can be exacerbated during chemotherapy cycles because of the cumulative effects of treatment. Patients often describe this fatigue as a profound sense of tiredness that isn't relieved by rest and can significantly impact their quality of life. Understanding that fatigue is a common manifestation of the body's response to chemotherapy helps healthcare providers manage this side effect through supportive care, education, and symptom management strategies.

While other therapies such as surgery, radiation, and hormone therapy can also lead to fatigue, chemotherapy is particularly well-documented for this side effect due to its systemic nature and impact on the entire body.
