i was wondering how often anyone here started with just a small lung nodule and it turned out to be cancer? i am a single mom of 4. a ct scan showed a 8mm non calcified lung nodule surrounded by ground glass opacity. i am scared to death it is lung cancer. i am the caregiver of my father who is going thru stage 3 lung cancer right now. he was just diagnosed 2 months ago. any info would be appreciated.
