Hi.
I understand the anxiety and the need to find someone who could give a reply, that this is not what you think it is.
The best way to settle the issue (and allay your fears) though, is to undergo a biopsy. If the swelling you report is under the right ear lobe - I think the risks of a biopsy at this site are fairly low.
For lung cancer, it is not typical to spread beyond the shoulders. The presence of swelling (which I assume are lymph nodes) below the ear seems too high for a lung cancer. What needs to be ruled out would be lymphoma or a cancer originating in the head (mouth, throat, etc). Discuss these with your doctor - lymphoma generally requires a larger amount of tissue during the biopsy.
Stay positive.
what did the doctor tell you about how the nodules looked on CT? sometimes the way they look tells them something about what to think about them.
