 [ Symptoms ] how long does pnuemonia bacteria live outside the body  my 84 yr old mom with heart disease and history of seizures was in an enclosed vehicle sitting in the exact seat where someone who had bacterial pnuemonia was brought to the hospital and admitted 12 hrs before i consider this being dangerously exposed am i correct or does the bacteria die sooner than i realize the windows were never opened due to cool weather thank you [ Disease ] hi it seems to be a well encapsulated cyst but unless a biopsy is done malignancy cannot be entirely ruled out as early stages of malignancy also look same the biopsy can be sent for histopathology to see for any tumour cells thanks
