Thanks for your question on Health Care Magic.
I can understand your sister's situation and problem.
I don't think they are checking pancreas. They might be checking for atypical or
fungal infection.
Cancer patients are usually immunosuppressive. And
chemotherapy further decrease the immunity.
So possibility of infection is much higher in cancer patients. Not only infection, possibility of
atypical infection like fungal, parasitic, tuberculosis, atypical bacterias etc is more in cancer patients.
So to prevent
recurrent pneumonia, we should get done bronchoscopy and BAL (
bronchoalveolar lavage) culture to identify the organism.
Sensitivity report is also needed to guide the effective antibiotic therapy.
So she is mostly transferred to other hospital for further investigation like bronchoscopy and BAL analysis.
Hope I have solved your query.
Wishing good health to your sister. Thanks.
