Another fun time is having a PET scan.

Now my experience will be different because over the last couple years I had a bout with colonrectal (I am 48) so that was fun.  After a year and a half of chemo treatments a month ago I was going through the follow up process of 6 months since the final surgery.  

I had a CT scan (which at least was better than the MRI since I wasn't fully enclosed) which unfortunately found a small mass (about the size of a pencil eraser in my lung).  

So I was brought into a special trailer (the PET scanner is so expensive they rent the equipment out to med centers for one day a week) where they had me sit in a chair (I swear I thought I would be strapped in) and they injected me with a radioactive dye.  The staff then left the room (I was too radioactive at that point), returning in 45 minutes when they did the scan.  Then for the rest of the day I was supposed to stay away from pregnant women and children under 5.  Scary stuff.

BTW, they eventually did decide the mass needed to be removed from the lung.  I went in 1.5 weeks ago, had surgery and was back at work 4 days later.  It is sore but I am coping.
