…patients obtaining formal mental health treatment. As in other studies, we found that approximately 10–14 percent of patients remained distressed at 6 months, despite receiving a variety of formal interventions. The same proportion of unresolved distress probably holds in other medical populations.

With my personal experience with cancer patients not one patient weren't in distress (in comparison with before the cancer) until the end of treatment.
Saying that only 15% percent of patients remained distressed after 6 months of cancer does not correspond to my experience.
Even treatable skin cancer reverberates deeply into the psyche of the patient and their families.
