I wish they would explain these scans in detail. What to expect and what the results mean before you ever have one.

The large NELSON study on lung cancer screening is the foundation for the Lung-RADS system. It grades lesions based on their probability of being malignant. Anything less than 6 mm is considered benign with a 0.5% chance of being cancer. To put that into perspective, you have a higher lifetime chance of dying crossing the street at 0.7%.

While it is not something to just ignore, it is not something you should spend any real amount of time worrying about. Just like looking both ways when crossing the street.

They are probably going to tell you to get another scan in a year. I do not even know how you got this one at 44, but because you have the lesions, they will want to follow them. They cannot even biopsy them until they are at least 8 mm, and many doctors will not try until 10 mm.

Finding lesions in lungs is common in healthy individuals. Finding them in a smoker is extremely common, and most smokers never develop lung cancer. We get sick all the time. Our lungs are subject to so much abuse beyond our control, and these are most likely artifacts from past illnesses or transient exposure.
Can't post a link but here's the studies full name .
