I just found out about an hour ago that dad's blood test came back with a low T-cell count. We (as in the rest of the family) are also noticing that his speech and memory problems are beginning to become noticeable again. I'm keeping my fingers crossed that it's only a side-effect of the radiation treatments he finished about two weeks ago, along with the industrial-strength chemicals he has to ingest on a daily basis. He does have a final follow-up appointment with his surgeon on Wednesday and there's another MRI to come soon. Hopefully it doesn't reveal any unwanted surprises.
Other than that, we're taking it day by day. The Christmas tree finally came down today, so now it's just dreary blah-ness for the next two months or so.
