The under-recognition of psychiatric conditions in cancer could be due to lack of awareness and/or unwillingness to seek treatment. Indeed, symptoms of depression often overlap with the physical manifestations of cancer or its treatment. Treatment for cancer (e.g., chemotherapy, biological therapy) often results in many of the symptoms needed for a diagnosis of depression such as fatigue, loss of appetite/weight, anhedonia, and psychomotor retardation. As such, it is difficult for patients (or their carers) to reasonably grasp the significance of these symptoms (Trask, 2004). More importantly, clinicians face difficulties in assessing oncology patients for psychiatric illnesses.
