Dear Dr. West and other contributing physicians,
I am a now 32 year old male. 2 years ago at 30 years of age in early March 2012 a 4mm pure GGO was discovered in my right lower lobe of the lung using a CT scan. No other symptoms were discovered (no lymphadenopathy, pleural effusion, coughing, etc.). Later that year in October, I did a repeat scan and the 4 mm pure GGO was still there, with quote: "absolutely no change whatsoever" and no symptoms, either. My pulmonologist said that the "likelihood that this represents cancer is exceedingly small". However, he recommended a follow-up (3rd) CT scan in 1.6 years to complete the follow-up.
Thank you VERY much for having posted all the great analysis on GGOs. My questions are as follows:
1) The fact that the GGO is still there... that's a bad thing right? i.e. the fact that the GGO is still there points to nascent cancer?
2) What other diseases could this finding represent? I have absolutely no symptoms associated with any lung disease, so does this fact make it more likely that the GGO represents nascent lung cancer?
3) Aren't two scans enough? My young age and coupled with the fact that there is absolutely no change whatsoever in the GGO and that cancer is exceedingly unlikely, wouldn't the third CT scan seem superfluous?
4) Moreover, wouldn't a 3rd CT scan increase my chance of cancer from exposure to X-rays (ionizing radiation)?
Thank you for any insight you may provide me with!! Note: I'm not asking for medical advice on my case, regardless of how these questions are answered, I will get my 3rd scan anyway :-)
