Looks like you’re well within the COVID window, so perhaps it’s just that. And you’re not even lymphopenic, just lower than before. Of course, it could be many other things, too. But I wish you good luck in the scan; that will likely give you piece of mind!
Like you, I’m interested in others’ stories, but I should add that CRC recurrence is a broad category with really variable facts. In those who’ve had their rectum removed, it’s usually mets, liver or lungs. If on W&W, or an early stage, local recurrence also occurs, and is usually luminal (recurrence sometimes happens in those that have had More radical surgery, but it is obviously of a different sort). I think most colon cancer recurrence is metastatic. All that to say stories will likely vary, and vary widely.
