Narrative Exposure Therapy to Reduce Symptoms of Traumatic Stress in Cancer Survivors

The main purpose of the study is to evaluate the feasibility, acceptability, and potential effectiveness of NET in reducing symptoms of traumatic stress (e.g., hyperarousal, avoidance, and intrusion) in cancer patients who are not in active treatment. Further aims include: * Can NET be effective in reducing symptoms of existential anxiety, anxiety, and depression in cancer patients who are not in active treatment? * Can NET improve the Quality of Life (QoL) of cancer patients who are not in active treatment? And are improvements in QoL associated to reduction of traumatic stress? * Can NET lead to post-traumatic growth? * Does the NET protocol need to be adapted to meet cancer patients' needs?
