Awareness of diagnosis and psychiatric morbidity among cancer patients--a study from South India.

Awareness regarding cancer diagnosis and its relationship to psychiatric morbidity was studied in 294 newly admitted cancer patients at an oncology center in South India. Fifty-four percent of patients were aware that they had cancer and were able to discuss their diagnosis; 46% of patients reported nonawareness of diagnosis. Discriminant function analysis revealed that oral cancers and relatives' awareness of the cancer was more prevalent in the group aware of diagnosis. More patients in the "unaware" group refused treatment for psychological distress. There was no difference between the two groups in patterns and prevalence of psychiatric morbidity. The study emphasizes the complexities in assessing awareness in cancer patients and a need to study its various components and relationship to psychological distress.
