Following up, I also read an article that using AI scans that were not for lung cancer (heart or other organs) but incidentally catch a lung nodule will be automatically flagged for follow up and not get lost through the cracks as in the past. My friend had a scan for her back years ago and they never mentioned a lung nodule, only her back, the nodule fell through the cracks. Luckily it was eventually found, but at least a year later. ~ Alisa
