Cancer-related fatigue is a common and debilitating symptom experienced by cancer patients. It is characterized by a persistent and overwhelming feeling of tiredness that is not relieved by rest or sleep. This type of fatigue can impact a patient's quality of life, ability to participate in daily activities, and overall well-being. Research in the area of cancer-related fatigue aims to better understand the mechanisms underlying this symptom, identify risk factors for developing fatigue, and develop effective interventions to manage and alleviate fatigue in cancer patients. Studies may investigate the physiological, psychological, and behavioral factors that contribute to fatigue in cancer patients, as well as the impact of treatments such as chemotherapy, radiation therapy, and surgery on fatigue levels. Overall, the goal of research in this area is to improve the quality of life for cancer patients by addressing and treating the debilitating symptoms of fatigue that often accompany a cancer diagnosis and treatment.
