Hi John, thank for the additional information. I think you’ll find this information from Veterans Affairs to be really helpful in answering some of the questions you have:
- Small Lung Nodules: What You Need to Know https://www.prevention.va.gov/docs/NodulesWhatYouNeedtoKnow.pdf

The article states:
“A nodule is generally considered small if it is less than 9 mm.”
“ Should I worry that I have a small nodule?
Usually a small nodule (less than 9 mm) is not a cancer, but it still could be an early cancer. The best ways to tell if a small nodule is possibly cancer are by:
1. Seeing how it looks on the LDCT scan, and
2. Seeing whether it grows over time.”
“ Most small nodules are not early lung cancer. Fewer than 5 percent of small nodules, or 5 out of 100, turn out to be cancer.”

I can imagine that you’re concerned. But it is comforting to know that 9mm is still considered small and that 95% of small nodules are not cancer. It’s also good that this was discovered and that your doctor is monitoring the situation closely. I’d like to bring @merpreb and @sueinmn into this conversation as they have experience with lung nodules and can perhaps help with what questions you might want to ask your doctor.
