Art therapy would, in practice be able to be offered concurrently to all other treatments for pain, and at at any point in the treatment journey. However for the purpose of this study, in order to understand art therapy's potential effectiveness, it is useful to narrow the focus of the research. It is reported that up to 50% of breast cancer patients suffer from chronic post treatment pain, that is, for an extended period of time after all treatment for cancer and despite being optimally treated already for their pain. In consultation with the Pain Team at the RM it was decided that breast cancer patients were a suitable cohort for this study.
