Depression, Anxiety, and Treatment Adherence among Cancer Patients: A Behavioral Health Perspective

Cancer is one of the leading causes of morbidity and mortality worldwide and is associated not only with physical suffering but also with severe psychological distress. Depression and anxiety are among the most common mental health problems experienced by cancer patients during diagnosis, treatment, and recovery. These psychological conditions significantly affect treatment adherence, emotional adjustment, and overall quality of life. The present empirical study examines depression, anxiety, and treatment adherence among cancer patients from a behavioral health perspective. The study was conducted among patients receiving treatment at Mahavir Cancer Sansthan, Patna. A total of 120 respondents were selected through purposive sampling method. Standardized psychological tools, structured questionnaires, interviews, and observation methods were used for data collection. The findings revealed that patients experiencing higher levels of depression and anxiety were more likely to show irregular treatment behavior and lower treatment adherence. Family support, counseling services, and positive coping behavior were found to improve emotional adjustment and adherence to treatment. The study highlights the need for integrating psycho-oncology services, mental health intervention, and behavioral counseling into cancer care systems.
