Hi Spike - Sorry, I should clarify. I did not have a recurrence of my removed cancer. My nodules were not new. I started with multiple nodules. I have multifocal lung cancer which means I have multiple lung nodules which are thought to be independent cancers (but some may not be) and they are in different stages of development.
These nodules start with ground glass opacity and may develop part solid components.
My first CT scan (not at Mayo) found a nodule in each lung. Mayo removed the largest one which was a 3.1cm stage 1b cancer. The nodule in the other lung has remained stable for a year so it may not be cancer. The remaining nodules are smaller and not necessarily picked up with a common CT scan. Mayo sets it equipment to pick up the smaller nodules which is why I know how many there are. They watch for growth and in that case the nodule may be treated. They also watch for the appearance of any new nodules. Sounds terrible but I feel fine.
