Step-by-step explanation:
True. Fatigue is known to be a common response to chemotherapy and radiation therapy. Chemotherapy and radiation therapy are both treatments commonly used for cancer, and they can have various side effects on the body. Fatigue is one of the most frequent and debilitating side effects reported by patients undergoing these treatments. It can occur due to the direct impact of the therapies on healthy cells and tissues, as well as the body's response to fighting cancer.
For example, chemotherapy drugs can affect normal rapidly dividing cells in the body, such as those in the bone marrow, hair follicles, and gastrointestinal tract, leading to fatigue. Radiation therapy can also cause fatigue by damaging healthy tissues in the treated area and triggering an immune response that contributes to exhaustion.
