A multisite study published in the Journal of Clinical Oncology involving 587 cancer survivors compared two mind-body programs: Mindfulness-Based Cancer Recovery (MBCR), which incorporates meditation and awareness practices, and Tai Chi/Qigong (TCQ), which uses gentle, slow movements to promote relaxation and balance. The participants—mostly women around age 61—selected their preferred program or were randomly assigned if they had no preference. The most prevalent cancer types among them were breast, prostate and gastrointestinal.

Both MBCR and TCQ demonstrated a positive impact on mood scores, surpassing those observed in the control group. Notably, TCQ produced the most relief from anger and depression, as well as an increase in energy levels. MBCR proved particularly effective in reducing tension and anxiety, although it did not significantly affect depression. Neither program exhibited any effect on confusion or fatigue, and the selection of a preferred program did not influence the outcomes.
