Breast Cancer is the most common cancer in women. After completion of successful therapy, may behavioral symptoms persist with over 20% of breast cancer survivors reporting chronic insomnia of greater than 6 months duration that fulfils clinical diagnostic criteria with associated functional limitations, decreased quality of life, and possible effects on long-term survival. Behavioral interventions are highly efficacious in the treatment of insomnia and preferred over hypnotic medication when insomnia is chronic. However, insomnia studies conducted in cancer are scarce. The proposed research builds upon program of study that has examined the efficacy of mind-body intervention, Tai Chi Chih (TCC), on health outcomes including sleep impairments. Preliminary studies show that TTC, a slow moving meditation, contributes to improvement in subjective sleep quality, sleep amounts and sleep efficiency. The investigators have further found that sleep, fatigue and proinflammatory cytokine activity are reciprocally related and that TCC decreases the mechanism through TCC carries its effects on sleep outcomes.
