OK. The term nodule is just used solid mass--something under the skin . But a nodule in the adrenal gland an a subpleural nodule would not be lymph nodes. They could both be benign or it's possible though very unlikely that they could be metastatic nodules from his cancer.

So are these mets ?

now the irinotecan not worked so what should be next step ?

Expert:  Dr. Chip replied 2 years ago.
I can't say about the adrenal nodule since that would be a very unusual area colon cancer met. The subpleural lung nodule could possibly be a met. But asking about what to do next is really a different topic than what you first asked. I'll be glad to continue but that would require either your accepting my offer of additional question and answer time or to rate my service page and then ask me the next question on a new page using this link
