## **Core Concept**
Depression is a significant psychological issue in patients with cancer, and its prevalence varies depending on the type of cancer. Certain types of cancer are associated with a higher risk of depression due to their impact on physical appearance, function, and prognosis.

## **Why the Correct Answer is Right**
Pancreatic cancer is often linked with a high incidence of depression. This association is thought to be due to several factors, including the cancer's poor prognosis, its location, which can cause early and severe symptoms, and its impact on bodily functions.
