<s>[INST] My Sister has been diagnosed with stage 4 colon cancer...She has undergone rigorous chemo over the last 4 months and now the latest scan shows the cancer is dormant....However, she has pneumonia and has had severe runs the last couple of days....She was released from the hospital a couple of weeks ago with the pneumonia and now has it again.....In a different hospital now...Should they be checking the pancreas? [/INST] Thanks for your question on Chat Doctor. I can understand your sisters 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 bacteria etc. is more in cancer patients. So to prevent recurrent pneumonia, we should get done bronchoscopy and BAD (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 BAD analysis. Hope I have solved your query. Wishing good health to your sister. Thanks. </s>
