1) Pancreatic cancer patients were being compared with persons hospitalized for cancerous diseases. Coffee may likely aggravate the pains of pancreatic cancer patients unlike other cancer patients because the latter's cancer diseases were not digestive.

It also allows the chief to decide whether the connection between the two will affect the reporter´s abilities or not.
