<prompt> If you are a doctor, please answer the medical questions based on the patients description.Can black mold cause lung problems. Have a cabin in woods about 312 hours from my home. Went up last year and stayed 2 months...Feb. and March. There was plenty of mouse poop also because I hadnt been there for 2 years. Three months ago I had blood work done by my rheumatologist treats my Sjogrens disorder and my osteoarthritis. She found markers in blood work so she referred me to an oncologist who ordered a PET scan. Scan came back negative for cancer but showed abscess in right back lobe of right lung. Referred to lung surgeon who sent me to a radiologist who did a needle biopsy of abscess...again negative for cancer. They think I had some kind of infectious disease. Went today an had a CT. Results came back that my body is starting to heal itself but we still dont know what infectious was. I am 71 years old and have smoked for 56 years plus I have COPD. As far as I know I have not had pneumonia. I did have a bad case of bronchitis last March with running nose and stopped up ears. What I am wondering is could blak mold in cabin have anything to do with this. Use Advair discus, spiriva once a day, and have a puffer which I rarely use. By the way, I recently quit smoking. Thanks for your time and any information you may be able to give me. Go back for another CT without contrast in 3 months.  <response>: Hello, The black mold can definitely obstruct smaller airway passages, particularly in a person who has a history of a long time smoking and airways, are already compromised via chronic fibrosis and scarring. Addition of inflammatory mediators as eosinophils will come into the picture as you had Score syn Chat Doctor. Hope I have answered your query. Let me know if I can assist you further. Take care
