I forgot to mention that I was having another PET scan this morning. I have had PET scans at the initial diagnosis and at the first two check-up points (see here for a brief description). I haven't needed one since then, though asked my oncologist for one prior to leaving for Edinburgh (we depart on 4th August). I thought I wouldn't have it until mid or late July, but then I received a call just a day or two ago telling me that I was booked in (they didn't ask when would be a good time; they just said, "Here is your scan time. Be there.").
In any case, if you're waiting for me to get to the point and post the result, then you forgot to read the title of this post!
