The purpose of this study is to learn more about older adults (age 65 and older) with cancer and their overall health by completing a survey called a "geriatric assessment" (GA). A GA is designed to gather information about a patient's nutritional status, mental health, spiritual health, social support, and memory. In addition, it informs health care providers about how well you carry out your daily activities and collects information on the other health problems you may have.
Sleep disturbance, particularly insomnia, is a common problem for cancer survivors. Insomnia can be described as excessive daytime napping, difficulty falling asleep, difficulty staying asleep, or waking up earlier than you would like. Insomnia can increase fatigue, impair physical function, impair immune function, cause circadian rhythms (known as your biological clock) to be disrupted and decrease quality of life. Because there is no ideal standard of care for effectively treating sleep problems in cancer survivors, the purpose of this study is to compare the effectiveness of three different treatments for improving sleep problems and determine which is best. The three treatments are yoga, survivorship health education, and cognitive behavioral therapy.
