I've been really worried because my mom used to feed pigeons on her balcony every day, and they pooped there for a whole year. We stopped doing it but now I'm concerned. Could this be why she has lung nodules now? Last year her CT scan only showed fibrosis, but this year there are lung nodules, and the largest is 9mm. Could feeding birds have caused this? I'm really looking for some advice here.
Pulmonologist opinion is advised to the patient.
