question: I was diagnosed wit a Mac infection (avium complex ). Had a cat scan and broncoscopy 4 months ago. The area was 1.5 centimeters in the right lung. Several days ago the cat scan was repeated and the area is smaller. I am not having any symptoms and the doctor said To come back in 1year for repeat cat scan. As. Far as treatment of drugs only if I have symptoms of the MAC. I feel that it should be done I less than a year . What is your opinion?
