Setback?

Paid a visit to the Onc today as a follow-up to last weeks CT scan. Laurie had an appointment this morning and the plan was to meet me there. When she took off in the truck, she noticed that it didn't feel right. Her return to the barn revealed a complete flat. Trusty Nick agreed to change the tire and make sure the spare had enough air but this put me 20 minutes behind schedule. I was doing a lot of active meditation on the drive downtown as I know how late patients can wreak havoc on an office.
Checked in, started filling out the "wellness" form, gave my blood sample and completed the form only to have my name called right away; less than 5 minutes. Weighed in, BP was 132/82 and temp was normal.
The Onc entered the room and asked how I was feeling and said there was some enlargement in the mesenteric lymph system around my intestines but that the enlargement was not cause for alarm. This was a change from my last scan so we will need to schedule another scan in 2 mos for a comparison.
Needless to say, I was a bit bummed as this 2 year appointment marks a crucial milepost in the success of the treatment.
I have been worried about all the CT scans as I cannot imagine that the excessive radiation exposure is good for anybody but the other side of the coin is uncertainty. My intuition tells me that catching this sooner than later is a better strategy. We can deal with the radiation issues later...it didn't work out so bad for Spiderman.
So...here's hoping that 8 weeks from now we discover this was a normal fluctuation and the enlargement was just a temporary reaction to some other invasion.
Knock knock.
