Fatigue caused by the<unk>  or its treatment often resolves if treatment is successful. However, some patients experience long-term or chronic fatigue. When strict definitions are used, about 20% of long-term, disease-free<unk>  survivors report fatigue. Under looser definitions, up to half of<unk>  survivors report fatigue. However, these studies are largely limited to patients with breast<unk> , or peripheral stem cell transplant or bone marrow transplant patients, and the incidence may be different for survivors of other<unk> s. Experiencing fatigue before treatment, being depressed or anxious, getting too little exercise, and having other medical conditions are all associated with higher levels of fatigue in post-treatment<unk>  survivors. Receiving multiple types of treatments, such as chemotherapy and radiation, is associated with more fatigue. Older adults have a higher risk of long-term fatigue.
