Thirty-five percent of breast cancer survivors, between 1 and 5 years following the diagnosis of breast cancer report symptoms of fatigue that fall into the disability range, despite remaining disease-free (Bower 2000, Lindley 1998). There is a paucity of information on what interventions may be most useful in reducing fatigue symptoms. Most interventions have focused on one factor that may contribute to fatigue such as sleep disturbance or pain. Exercise interventions have been tried but have mostly focused on fatigue during chemotherapy or radiation therapy and have not addressed the problem of persistent fatigue.
