Margin of error??

I know what you’re talking about and I am dealing with the same situation, I get the results from the ct scan and it sounds like things are going on but they deemed it as stable. I’m still not sure what they are doing and getting more information isn’t easy to get, most of my questions are just not answered and if I were able to get new doctors to help me I would but doctors are hard to find where I live, sometimes I just feel like a trapped person when it comes to my health and also my world. I think that you should keep asking questions to get better understanding of your scans, if you’re not satisfied then find another doctor, I’m assuming that you can do that where you’re located, if not then I’m sorry, welcome to my world, best wishes.

@lharfield It might help to know that in lungs, GGO (ground glass opacities) are considered temporary artifacts, and mostly will eventually resolves. They are usually indicators of a current or previous infection, and as the lungs heal they dissipate.
If a solid nodule or cavity increases in size, this is of more concern. It may be indicative of a tumor (nodule) or permanent lung damage (cavity.)

What underlying lung condition(s) do you have?

No underlying conditions Sue

Could increase in size be based on the radiologist who read it?

It went from an 8 to a 10 in five months!😪

@lhatfield96, These scans are interpreted by radiologists that may have slightly different views on what they are seeing. I'm not a doctor or radiologist, but I can only imagine how difficult it is to measure the haze of GGO. The difference of 2mm could be due to differences in interpretation. Having a doctor sit with you and compare the images from both scans would help to answer your question/s.
Do you have a follow up appointment scheduled with the doctor who ordered the test, or with a family med doc/general practitioner? If not, I would call and get an appointment set up to get your questions answered.

That world is larger than you might think . I get 15 minutes with my primary Doctor today. An hour to get there , to have weight , BP , temp and oxy check. My doctor hesitates to speak about my COPD. Tells me I need to talk to my pulmonologist . They do the same thing at his office . No new ideas or treatments . I have asked for a bipap . Wants me to spend the night in a sleep center . ( His sleep center) That I will not do. They do have self adjusting bipap machines. I guess he does’t know that. We do the best we can where we are . Blessed Be, Crystalina

I have subsolid nodules that have been present since my diagnosis in 2010. Sometimes they grow, other times they shrink. They've never developed a solid component.

@denzie What exactly is a sub solid nodule? They called mine a sub solid ground glass opacity in my first screen. It's so confusing and my recent report just said it was a GGN and did not mention a sub solid part like my initial one did. I am making myself nuts and praying that it's not true growth but a margin of error. They did not recommend any follow up and said it was stable. Growth isn't stable to me!

I understand being nervous when you see something that appears to be growing, but let's try to put it in perspective. First of all, nothing indicates the spot has increased in density and now appears to be a nodule.

As for size, we are talking about an increase of two millimeters - just over 1/16th of an inch. At its largest point, what is being observed is 4/10 inch long and less than 3/10 inch in width, about the size of a sunflower kernel.

Since it is not solid, it can look different depending on the angle of the image, whether you are inhaling or exhaling, if you have mucus in your lungs and a lot of other variables.

Between Radiology and the pulmonologist, the scan is read by at least 3 doctors accustomed to looking at lungs.

I know it is harder to do than to say, but I think you need to arrange to talk to the doctor, listen carefully to their explanation, then try to quit worrying.
