<qa>  What is the name of the study that has not been studied in Veterans?With advances in the detection and treatment of cancer, there are now 14 million cancer survivors in the U.S., 500,000 of whom are treated in the Veterans Health Administration. The mental and physical health consequences of cancer and its treatment may affect a Veterans functioning and re-integration back into family, work, and daily life. Recent studies suggest that yoga may be an effective intervention for improving both the physical and mental health of individuals after cancer, although this has not been studied in Veterans. This study has three components: 1 Determine factors that increase participation in Yoga by Veterans using individual interviews and focus group; 2 Create a Yoga protocol for Veterans adapted from an existing empirically supported treatment, akin to a phase 1 clinical trial for safety and tolerability; 3 Evaluate the efficacy of Yoga for improving fatigue, insomnia, anxiety, and depression after treatment for colorectal cancer, akin to a phase 2 trial with randomization.
