A review of 12 studies investigating the use of art therapy in cancer patients by Wood, Molassiotis, and Payne (2010) investigated the symptoms of emotional, social, physical, global functioning, and spiritual controls of cancer patients. They found that art therapy can improve the process of psychological readjustment to the change, loss, and uncertainty associated with surviving cancer. It was also suggested that art therapy can provide a sense of "meaning-making" because of the physical act of creating the art. When given five individual sessions of art therapy once per week, art therapy was shown to be useful for personal empowerment by helping the cancer patients understand their own boundaries in relation to the needs of other people. In turn, those who had art therapy treatment felt more connected to others and found social interaction more enjoyable than individuals who did not receive art therapy treatment. Furthermore, art therapy improved motivation levels, abilities to discuss emotional and physical health, general well-being, and increased global quality of life in cancer patients.
