    Super interested to see

    what the scan tomorrow shows.  That's a repeat scan because the surgeon is not happy with the one done weeks ago.

    I'm wondering if there will be any change in any of it.  I know, I know, it's so short-term in between the two, so likely not, but I'm still really anxious to see if anything has changed.

    Hahaha... this is the last weeked with a fully-assembled John.

    Any changes will probably be unmeasurable

    Any time we measure anything -- temperature, speed, weight, etc, there is uncertainty in the measurement.  The same goes for CT scans (or MRI's, ultrasounds, etc).  Any change in two weeks will probably be within the measurement precision.  For a CT scan, that is somewhere around 2 mm.  (older ones might be 1/2 cm).  Given the rate that tumors grow, a rapidly growing RCC tumor is 2 cm/yr; typical is 1/2 cm/yr.  So, at 2 cm / yr, that would be a 0.8 mm in two weeks, which is within the measurement uncertainty -- if they see 1 mm of growth, it could be that they underestimated it last time, or are over estimating it now.
