@jenniferhunter I've had multiple small lung nodules for 3 to 4 years now. Never large enough to biopsy. Some have disappeared, some stay the same. Largest is like 5 mm I think, maybe 6 mm. I see my pulmonary doctor every year, following a CT scan which we review together in his office. I've had doctors claim I got them because of breathing Los Angeles air or otherwise breathing in highway tire road dust. I'm counting on them not being cancerous. That some have disappeared is a good sign. I love getting the checkups. My ex-wife just died of stage 4 metastatic pulmonary cancer, never a smoker, fought the chemo battle for 2 years, never operated. Her clinical trial obviously failed. Very sorry for her. She was 78 years old. I'm 78 also.
